Universal level statistics of the out-of-time-ordered operator

Efim B. Rozenbaum, Sriram Ganeshan, and Victor Galitski

Phys. Rev. B 100, 035112 (2019) - Published 15 July, 2019

Here, the authors introduce the “Lyapunovian” – a new tool to study quantum chaos. It unifies the conventional random matrix theory approach with that based on the out-of-time-ordered correlator and generalizes them. Level statistics of the Lyapunovian under appropriate projections transitions as a function of time from an uncorrelated Poisson-like distribution to the Wigner-Dyson form. This new tool connects the semiclassical Lyapunov growth at early times, when the quantum effects are weak, to universal level repulsion that hinges on strong quantum interference effects.

Magnetohydrodynamics in graphene: Shear and Hall viscosities

B. N. Narozhny and M. Schütt

Phys. Rev. B 100, 035125 (2019) - Published 24 July, 2019

Electronic hydrodynamics has matured into a vibrant field with new experiments regularly uncovering exciting aspects of collective behavior of strongly interacting many-body systems. Henceforth, quantitative explanation of the observed phenomena would be required from the theory. Here, the authors calculate experimentally relevant values of the shear and Hall viscosities in graphene as functions of temperature, carrier density, and magnetic field, showing quantitative agreement with the available experimental data without resorting to any fitting procedures.

Floating Wigner crystal with no boundary charge fluctuations

Mathieu Lewin, Elliott H. Lieb, and Robert Seiringer

Phys. Rev. B 100, 035127 (2019) - Published 25 July, 2019

Different definitions of the ground-state energy of the uniform electron gas (jellium) exist. In one, electrons are placed in a neutralizing uniform background. In another, there is no background but the electron density is constrained to be constant, as is appropriate for density functional theory. In the third, electrons interact with periodic images of themselves (periodic boundary conditions). Due to the long-range nature of the Coulomb potential, charge fluctuations near the boundary have made it difficult to prove that their energies coincide, but that is achieved here by a novel floating-crystal trial state.

Adiabatic variation of the charge density wave phase diagram in the 123 cuprate (CaxLa1−x)(Ba1.75−xLa0.25+x)Cu3Oy

M. Bluschke, M. Yaari, E. Schierle, G. Bazalitsky, J. Werner, E. Weschke, and A. Keren

Phys. Rev. B 100, 035129 (2019) - Published 25 July, 2019

In this study, isovalent chemical substitution is used to tune adiabatically structural and electronic degrees of freedom in a cuprate high-temperature superconductor. The strength of charge density modulations in the electronic states responsible for superconductivity responds dramatically to this substitution as demonstrated by resonant x-ray scattering experiments. These measurements indicate that the energy scale of the enigmatic pseudogap is not determined by charge density wave (CDW) order and suggest a competition between CDWs and precursor superconductivity at temperatures above 200 K.

Ultrafast relaxation dynamics of highly excited hot electrons in silicon

Hiroshi Tanimura, Jun'ichi Kanasaki, Katsumi Tanimura, Jelena Sjakste, and Nathalie Vast

Phys. Rev. B 100, 035201 (2019) - Published 9 July, 2019

This combined experimental and theoretical investigation reveals that the relaxation of electrons at high excess energy in the conduction band of silicon takes place as two distinctive processes with different time scales, an ultrafast momentum quasiequilibration over the Brillouin zone within 10 fs and a slower energy relaxation of the hot-electron ensembles. The energy relaxation rate is proportional to the electronic density of states over a large range of excess energies. The work generalizes the concept of hot-electron ensembles in semiconductors.

The sixteenfold way and the quantum Hall effect at half-integer filling factors

Ken K. W. Ma and D. E. Feldman

Phys. Rev. B 100, 035302 (2019) - Published 3 July, 2019

Cooper pairing of composite fermions is responsible for the observed half-integer quantum Hall plateaus. Different pairing types are believed to be present in different materials under different conditions. Their nature is hotly debated. Here, the authors uncover mother-daughter relations among all possible topological orders in composite-fermion superfluids. The mother-daughter relations allow for a uniform description of the sixteen types of order and are used to predict smoking-gun experimental signatures of each of the types.

Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation

E. Estrecho, T. Gao, N. Bobrovska, D. Comber-Todd, M. D. Fraser, M. Steger, K. West, L. N. Pfeiffer, J. Levinsen, M. M. Parish, T. C. H. Liew, M. Matuszewski, D. W. Snoke, A. G. Truscott, and E. A. Ostrovskaya

Phys. Rev. B 100, 035306 (2019) - Published 15 July, 2019

Bosonic condensates of exciton polaritons typically coexist and interact with an incoherent reservoir, which undermines measurements of key parameters of the condensate. Here, the authors overcome this limitation by creating a high-density polariton condensate in an optically induced box trap. In this interaction-dominated Thomas-Fermi regime, the condensate is fully separated from the reservoir, which enables a direct measurement of the polariton-polariton interaction strength. The results of the measurement are in agreement with theoretical predictions.

99% beta factor and directional coupling of quantum dots to fast light in photonic crystal waveguides determined by spectral imaging

L. Scarpelli, B. Lang, F. Masia, D. M. Beggs, E. A. Muljarov, A. B. Young, R. Oulton, M. Kamp, S. Höfling, C. Schneider, and W. Langbein

Phys. Rev. B 100, 035311 (2019) - Published 30 July, 2019

Semiconductor quantum dots in photonic crystal waveguides are building blocks for quantum technology. Placing the dots at locations where the waveguide modes have circular polarization enables light emission in only one direction with a high probability of coupling to the mode, the beta factor. The authors use spectral imaging to determine the beta factor and the directionality, doing away with assumptions on emission rates into nonguided modes. In the fast-light regime, they find coupling, close to unity, and determine the quantum-dot position inside the waveguide.

Mapping the perturbation potential of metallic and dipolar tips in tunneling spectroscopy on MoS2

Nils Krane, Christian Lotze, Nils Bogdanoff, Gaël Reecht, Lei Zhang, Alejandro L. Briseno, and Katharina J. Franke

Phys. Rev. B 100, 035410 (2019) - Published 9 July, 2019

Scanning tunneling spectroscopy is a powerful tool to investigate the electronic structure of molecules on surfaces. The technique requires the application of a potential difference between sample and tip. Whereas the potential is constant along a metallic substrate, it is inhomogeneous along the surface of an insulating layer such as MoS2. The authors now show that the inhomogeneous shape of the electric potential and dipole contributions perturb the electronic states of the molecules leading to an apparent shift of the electronic states along extended molecules.

Designing flat bands by strain

Zhen Bi, Noah F. Q. Yuan, and Liang Fu

Phys. Rev. B 100, 035448 (2019) - Published 31 July, 2019

Magic angle twisted bilayer graphene (MATBG) is an exciting new system for flat electronic bands and correlated physics. However, heterostrains are ubiquitous in the TBG samples, and their role on the electronic properties has not been clear. Here, the authors show that heterostrains generically broaden the flat bands in MATBG. This explains many puzzling results from transport and scanning tunneling spectroscopy experiments. Furthermore, one can utilize the heterostrain to engineer highly flexible moiré flat bands in bilayer transition metal dichalcogenides, suggesting another platform to be exploited.

Engineering the Floquet spectrum of superconducting multiterminal quantum dots

Régis Mélin, Romain Danneau, Kang Yang, Jean-Guy Caputo, and Benoît Douçot

Phys. Rev. B 100, 035450 (2019) - Published 31 July, 2019

The authors have applied Floquet theory to the dynamics of Andreev bound states in voltage-biased multiterminal superconducting quantum dots. They have established that the spectrum of the sharp Floquet resonances can be probed by noise in the microwave domain. This full analogy with photocurrent spectroscopy of Wannier-Stark ladders in semiconducting superlattices paves the way towards a new kind of a Floquet qubit in superconducting devices.

Scanning tunneling spectroscopy is a powerful tool to investigate the electronic structure of molecules on surfaces. The technique requires the application of a potential difference between sample and tip. Whereas the potential is constant along a metallic substrate, it is inhomogeneous along the surface of an insulating layer such as MoS2. The authors now show that the inhomogeneous shape of the electric potential and dipole contributions perturb the electronic states of the molecules leading to an apparent shift of the electronic states along extended molecules.

Magic angle twisted bilayer graphene (MATBG) is an exciting new system for flat electronic bands and correlated physics. However, heterostrains are ubiquitous in the TBG samples, and their role on the electronic properties has not been clear. Here, the authors show that heterostrains generically broaden the flat bands in MATBG. This explains many puzzling results from transport and scanning tunneling spectroscopy experiments. Furthermore, one can utilize the heterostrain to engineer highly flexible moiré flat bands in bilayer transition metal dichalcogenides, suggesting another platform to be exploited.

The authors have applied Floquet theory to the dynamics of Andreev bound states in voltage-biased multiterminal superconducting quantum dots. They have established that the spectrum of the sharp Floquet resonances can be probed by noise in the microwave domain. This full analogy with photocurrent spectroscopy of Wannier-Stark ladders in semiconducting superlattices paves the way towards a new kind of a Floquet qubit in superconducting devices.
