Fractional Chern insulator states in multilayer graphene moiré superlattices

Zhongqing Guo, Xin Lu, Bo Xie, and Jianpeng Liu

Phys. Rev. B 110, 075109 (2024) - Published 6 August, 2024

As the zero-field analogue of the fractional quantum Hall states, fractional Chern insulator states emerge from topologically nontrivial flat bands realized in lattice systems. Recently, a series of fractionally quantized Hall resistance plateaus have been observed in rhombohedral pentalayer graphene-hBN moiré superlattices under zero magnetic field, needing theoretical understanding. The authors have developed a theoretical workflow, discovering both integer and fractional Chern insulator states in rhombohedral multilayer graphene-hBN moiré superlattices, which are consistent with recent experimental results.

Raimundas Sereika, Greeshma C. Jose, Silu Huang, Rongying Jin, William A. Shelton, Weiwei Xie, Jiyong Zhao, Barbara Lavina, Esen E. Alp, Yuming Xiao, Dongzhou Zhang, Yogesh K. Vohra, and Wenli Bi

Phys. Rev. B 110, 075127 (2024) - Published 13 August, 2024

EuMnSb2 is a unique material platform to realize magnetic control of topological quasiparticles. The authors employ here external pressure as a tuning mechanism to investigate the valence and magnetic properties through a series of synchrotron x-ray diffraction and spectroscopy techniques. They find a continuous valence change accompanied by a large increase in the magnetic ordering temperature in the Eu sublattice. This enhancement is likely due to the reduced Eu ion distance and increased 4f-5d orbital mixing.

Nonlocal machine-learned exchange functional for molecules and solids

Kyle Bystrom and Boris Kozinsky

Phys. Rev. B 110, 075130 (2024) - Published 15 August, 2024

Here, the authors use machine learning and exact physical constraints to design a nonlocal exchange functional for both molecular and solid-state systems. The model is computationally efficient, achieves hybrid-DFT accuracy on molecular benchmarks, and improves the accuracy of band gap predictions over semilocal DFT. To demonstrate the efficiency and accuracy of the model, the authors compute charged point defect transition levels in silicon in good agreement with experiment, a task previously only possible with more expensive hybrid DFT calculations.

Anomalous electronic energy relaxation and soft phonons in the Dirac semimetal Cd3As2

Rishi Bhandia, David Barbalas, Run Xiao, Juan R. Chamorro, Tanya Berry, Tyrel M. McQueen, Nitin Samarth, and N. P. Armitage

Phys. Rev. B 110, 075131 (2024) - Published 15 August, 2024

The authors investigate here the energy and momentum relaxation in the Dirac semimetal Cd3As2 using linear and nonlinear terahertz spectroscopy. They find that the temperature dependence of these rates is consistent with quasielastic phonon-electron scattering down to the lowest temperatures measured. These findings highlight how the Dirac semimetal’s unique lattice dynamics, including its low thermal conductivity and soft phonons, offers new insights into potential applications of Cd3As2 for electronic and optoelectronic devices.

Quasiparticle and excitonic properties of monolayer 1T′ WTe2 within many-body perturbation theory

Jinyuan Wu, Bowen Hou, Wenxin Li, Yu He, and Diana Y. Qiu

Phys. Rev. B 110, 075133 (2024) - Published 16 August, 2024

Among existing band structure predictions of the topological monolayer 1T‘-WTe2, only a semi-empirical hybrid functional has been able to reproduce the gapped electronic structure observed by angle-resolved photoemission spectroscopy (ARPES). Here, the authors demonstrate that the electronic band structure can be obtained by updating the quasiparticle wave functions within many-body perturbation theory (MBPT). Moreover, Bethe-Salpeter equation (BSE) on top of the gapped band structure leads to negative exciton frequencies, suggesting a possible exciton instability consistent with experimental evidence.

Single-shot quantum error correction in intertwined toric codes

Charles Stahl

Phys. Rev. B 110, 075143 (2024) - Published 23 August, 2024

Ordinary fault-tolerant quantum memories, such as the toric code, require many rounds of measurements before a single round of error correction can be performed. On the other hand, single-shot quantum memories require only a single round (“shot”) of measurements per round of correction. Using physical motivations, the author shows here how to build a single-shot quantum memory out of ordinary toric codes, allowing for connections to toric code physics including the confinement and deconfinement of anyons.

Electron-phonon interaction and band structure renormalization using Gaussian orbital basis sets

Gerrit Mann, Michael Rohlfing, and Thorsten Deilmann

Phys. Rev. B 110, 075145 (2024) - Published 23 August, 2024

Electron-phonon interactions lead to a renormalization of the electronic band structure. Its first-principles evaluation is computationally expensive and relies on specific approximations. The authors present here an ab initio approach that combines non-adiabatic Allen-Heine-Cardona theory with supercell calculations in a Gaussian basis. This allows the inclusion of contributions beyond the rigid-ion approximation and thereby increases the accuracy, while maintaining moderate computational costs.

Ramakanta Chapai, Gordon Peterson, M. P. Smylie, Xinglong Chen, J. S. Jiang, David Graf, J. F. Mitchell, and Ulrich Welp

Phys. Rev. B 110, 075152 (2024) - Published 27 August, 2024

Topological superconductors are studied for their potential to host Majorana fermions, crucial for fault-tolerant quantum computing. These materials require both topologically nontrivial bands and a superconducting ground state, making them rare. Pd3Bi2Se2, with a nonzero Z2 topological invariant, is one such promising candidate topological superconductor. Here, the authors investigate the superconducting properties, magnetotransport, and quantum oscillations of Pd3Bi2Se2. The quantum oscillation measurements, supported by band structure calculations, confirm Pd3Bi2Se2’s nontrivial topology, reinforcing its potential as a topological superconductor.

Quantization of intraband and interband Berry phases in the shift current

A. Alexandradinata

Phys. Rev. B 110, 075159 (2024) - Published 27 August, 2024

The theory of the shift current has thus far been geometrical without being topological. This means that the real-space displacement of a photoexcited quasiparticle depends on the geometric Berry phase, but the Berry phase is not quantized to a rational multiple of 2π in any known material. The author rectifies this status quo by introducing a new class of topological insulators whose wave-function topology is only compatible with materials lacking a center of inversion.

Detecting the spread of valence-band Wannier functions by optical sum rules

Luis F. Cárdenas-Castillo, Shuai Zhang, Fernando L. Freire, Jr., Denis Kochan, and Wei Chen

Phys. Rev. B 110, 075203 (2024) - Published 20 August, 2024

For three-dimensional semiconductors and insulators, the authors elaborate here that the imaginary part of dielectric function integrated over frequency gives the spread of valence-band Wannier functions, which characterizes how insulating is the material. For two-dimensional materials, their opacity divided by frequency and then integrated over frequency does the same job.

Quantum Hall interferometry at finite bias with multiple edge channels

Zezhu Wei, D. E. Feldman, and Bertrand I. Halperin

Phys. Rev. B 110, 075306 (2024) - Published 28 August, 2024

Electronic interferometry has emerged as a powerful tool to extract information about 2D electron liquids, including fractional statistics of anyons in the quantum Hall effect. The existing theory mostly addresses the conceptually simplest case of a single edge mode, but recent experiments have focused on multichannel edges. Motivated by recent experiments, the authors consider here a quantum Hall interferometer model containing two edge modes and study theoretically the current-voltage curves for various values of the relative edge velocities, interaction strength, and the temperature. When the inner mode is completely reflected and the outer mode is partially transmitted, the authors find striking features related to resonance of excitations of the closed inner channel. Fluctuations in the charge of the closed inner mode, caused by sparse tunneling events, lead to an exponential suppression of the interference visibility at high voltages, in agreement with experiments.

Helical trilayer graphene in magnetic field: Chern mosaic and higher Chern number ideal flat bands

Anushree Datta, Daniele Guerci, Mark O. Goerbig, and Christophe Mora

Phys. Rev. B 110, 075417 (2024) - Published 14 August, 2024

As compared to other prominent twisted-layered systems that feature flat bands, twisted helical trilayer graphene at magic angles displays flat bands with Chern number higher than one, and features a Chern mosaic. The authors show here intriguing topological phase transitions with increasing Chern numbers in the flat bands under a perpendicular magnetic field. The associated wavefunctions are derived, and a set of hidden wavefunctions are shown to play a crucial role in the topological transitions and increase of Chern numbers.

Near-field radiative heat transfer between a nanoparticle and a graphene grating

Minggang Luo, Youssef Jeyar, Brahim Guizal, and Mauro Antezza

Phys. Rev. B 110, 075423 (2024) - Published 19 August, 2024

The authors explore here the near-field radiative heat transfer between a planar fused silica slab coated with a strip graphene grating and a laterally and/or normally shifted fused silica nanoparticle. For this study, the authors utilize a scattering matrix approach derived from the Fourier modal method augmented with local basis functions. The study identifies a general rule of thumb that delineates two distinct asymptotic regimes: the inhibition regime, in which a lateral shift of the nanoparticle reduces the heat transfer; neutral regime, where the lateral shift’s effect on heat transfer becomes negligible. A critical point for understanding the effect of lateral shift on radiative heat transfer is found at the ratio of normal shift to grating period d/D≈0.85.

Optical mode enabled manipulation of topological phase in waveguide-based scattering networks

Changyu Zhou, Zhenwei Xie, Ting Lei, Yao Zhang, Qinmiao Chen, and Xiaocong Yuan

Phys. Rev. B 110, 075424 (2024) - Published 19 August, 2024

Topologies in scattering networks are governed by certain parameters that allow manipulation of their topological phases. The authors propose here a scheme to control topological phases using the waveguide mode as a controlling means. They experimentally validate this with a ring optical-waveguide device, demonstrating that changing the mode switches the robust interface state’s direction, proving that the network’s topological phase can be controlled by specific waveguide modes.

For three-dimensional semiconductors and insulators, the authors elaborate here that the imaginary part of dielectric function integrated over frequency gives the spread of valence-band Wannier functions, which characterizes how insulating is the material. For two-dimensional materials, their opacity divided by frequency and then integrated over frequency does the same job.

Phys. Rev. B 110, 075306 (2024) - Published 28 August, 2024

Electronic interferometry has emerged as a powerful tool to extract information about 2D electron liquids, including fractional statistics of anyons in the quantum Hall effect. The existing theory mostly addresses the conceptually simplest case of a single edge mode, but recent experiments have focused on multichannel edges. Motivated by recent experiments, the authors consider here a quantum Hall interferometer model containing two edge modes and study theoretically the current-voltage curves for various values of the relative edge velocities, interaction strength, and the temperature. When the inner mode is completely reflected and the outer mode is partially transmitted, the authors find striking features related to resonance of excitations of the closed inner channel. Fluctuations in the charge of the closed inner mode, caused by sparse tunneling events, lead to an exponential suppression of the interference visibility at high voltages, in agreement with experiments.

As compared to other prominent twisted-layered systems that feature flat bands, twisted helical trilayer graphene at magic angles displays flat bands with Chern number higher than one, and features a Chern mosaic. The authors show here intriguing topological phase transitions with increasing Chern numbers in the flat bands under a perpendicular magnetic field. The associated wavefunctions are derived, and a set of hidden wavefunctions are shown to play a crucial role in the topological transitions and increase of Chern numbers.

The authors explore here the near-field radiative heat transfer between a planar fused silica slab coated with a strip graphene grating and a laterally and/or normally shifted fused silica nanoparticle. For this study, the authors utilize a scattering matrix approach derived from the Fourier modal method augmented with local basis functions. The study identifies a general rule of thumb that delineates two distinct asymptotic regimes: the inhibition regime, in which a lateral shift of the nanoparticle reduces the heat transfer; neutral regime, where the lateral shift’s effect on heat transfer becomes negligible. A critical point for understanding the effect of lateral shift on radiative heat transfer is found at the ratio of normal shift to grating period d/D≈0.85.

Optical mode enabled manipulation of topological phase in waveguide-based scattering networks

Topologies in scattering networks are governed by certain parameters that allow manipulation of their topological phases. The authors propose here a scheme to control topological phases using the waveguide mode as a controlling means. They experimentally validate this with a ring optical-waveguide device, demonstrating that changing the mode switches the robust interface state’s direction, proving that the network’s topological phase can be controlled by specific waveguide modes.
