Many-body localization landscape

Shankar Balasubramanian, Yunxiang Liao, and Victor Galitski

Phys. Rev. B 101, 014201 (2020) - Published 6 January, 2020

Recently, a structure called the localization landscape was shown to accurately predict the location of eigenfunctions in the single-particle Anderson model. Here, the authors generalize the localization landscape to a large class of interacting many-body systems. They use the many-body localization landscape (MBLL) to prove decay estimates of eigenstates, and show robustness of the MBLL to weak interactions and hopping by deriving a convergent locator expansion. This establishes the MBLL as a method for efficiently estimating low-energy eigenstates and understanding possible phases in MBL models.

Variational Schrieffer-Wolff transformations for quantum many-body dynamics

Jonathan Wurtz, Pieter W. Claeys, and Anatoli Polkovnikov

Phys. Rev. B 101, 014302 (2020) - Published 10 January, 2020

The description of nonequilibrium dynamics in interacting quantum systems is a long-standing challenge within condensed matter physics. In this theoretical work, the authors introduce a method to block-diagonalize low-energy sectors of strongly interacting Hamiltonians by variationally computing generators of rotations, equivalent to a nonperturbative dressing of quasiparticle excitations. This procedure allows for the calculation of effective dynamics including quenches and response functions, as is demonstrated in a Fermi-Hubbard model and an integrability-broken XY model, both of which demonstrate excellent convergence.

Acoustic signatures of the phase transitions in the antiferromagnet U2Rh2Sn

D. I. Gorbunov, A. V. Andreev, I. Ishii, K. Prokeš, T. Suzuki, S. Zherlitsyn, and J. Wosnitza

Phys. Rev. B 101, 014408 (2020) - Published 8 January, 2020

The 5f electrons of uranium-based intermetallic compounds are known to be between localized and itinerant. It is very hard to determine the degree of their localization. Here, by using sophisticated ultrasound experiments and a crystal electric field analysis for U2Rh2Sn, the authors conclude that the 5f electrons tend to be localized in the paramagnetic regime.

Tuning entanglement by squeezing magnons in anisotropic magnets

Ji Zou, Se Kwon Kim, and Yaroslav Tserkovnyak

Phys. Rev. B 101, 014416 (2020) - Published 13 January, 2020

There has been much recent interest in coherently preparing and manipulating entanglement in various systems, stimulated by its importance in quantum information science. Here, the authors discuss entanglement between individual spins within anisotropic magnets in thermodynamic equilibrium, suggesting magnetic materials as a natural resource for processing quantum information. Furthermore, they show that entanglement can jump discontinuously by varying an applied magnetic field, which can potentially serve as a switch for quantum information processing tasks.

Field and temperature dependence of the skyrmion lattice phase in chiral magnet membranes

David M. Burn, Shasha Wang, Weiwei Wang, Gerrit van der Laan, Shilei Zhang, Haifeng Du, and Thorsten Hesjedal

Phys. Rev. B 101, 014446 (2020) - Published 29 January, 2020

Using high-resolution small-angle resonant elastic x-ray scattering, the authors study here the field and temperature dependence of the skyrmion lattice in FeGe membranes. In stark contrast to Cu2OSeO3, the lattice constant and skyrmion size undergo a continuous evolution within the skyrmion phase pocket, whereby the lattice constant changes by up to 15%. Micromagnetic modeling shows that the competing energy terms contributing to the formation of the skyrmion lattice fully explain the observed breathing behavior.

Magnetism of Ir5+-based double perovskites: Unraveling its nature and the influence of structure

M. A. Laguna-Marco, E. Arias-Egido, C. Piquer, V. Cuartero, L. Hernández-López, P. Kayser, J. A. Alonso, J. A. T. Barker, G. Fabbris, C. A. Escanhoela, Jr., and T. Irifune

Phys. Rev. B 101, 014449 (2020) - Published 30 January, 2020

Iridates having pentavalent Ir5+ ions have emerged in the last years as an exciting playground to tune the atomic magnetic ground state from nonmagnetic J=0 to magnetic J≠0 by either distortions of the IrO6 octahedra or increased orbital overlap. Here, the authors analyze the origin of the magnetic response observed in Sr2YIrO6 and reveal that in this case neither volume contraction nor structural distortions are sufficient to cause any change in the magnetic state of the Ir5+ ions.

Selective hybridization between the main band and the superstructure band in the Bi2Sr2CaCu2O8+δ superconductor

Qiang Gao, Hongtao Yan, Jing Liu, Ping Ai, Yongqing Cai, Cong Li, Xiangyu Luo, Cheng Hu, Chunyao Song, Jianwei Huang, Hongtao Rong, Yuan Huang, Qingyan Wang, Guodong Liu, Genda Gu, Fengfeng Zhang, Feng Yang, Shenjin Zhang, Qinjun Peng, Zuyan Xu, Lin Zhao, Tao Xiang, and X. J. Zhou

Phys. Rev. B 101, 014513 (2020) - Published 29 January, 2020

Unexpected hybridization between the main band and the superstructure band in the Bi2Sr2CaCu2O8+δ (Bi2212) superconductor is revealed by high-resolution laser-based angle-resolved photoemission measurements. It can be understood by considering the selective hybridization of bands from the bilayer splitting in Bi2212. These observations indicate that the origin of the superstructure bands is intrinsic to the CuO2 planes. Understanding the physical properties and superconductivity in Bi2212 needs consideration of the complete Fermi surface topology, involving the main bands, the superstructure bands, and their interactions.

Using high-resolution small-angle resonant elastic x-ray scattering, the authors study here the field and temperature dependence of the skyrmion lattice in FeGe membranes. In stark contrast to Cu2OSeO3, the lattice constant and skyrmion size undergo a continuous evolution within the skyrmion phase pocket, whereby the lattice constant changes by up to 15%. Micromagnetic modeling shows that the competing energy terms contributing to the formation of the skyrmion lattice fully explain the observed breathing behavior.

Iridates having pentavalent Ir5+ ions have emerged in the last years as an exciting playground to tune the atomic magnetic ground state from nonmagnetic J=0 to magnetic J≠0 by either distortions of the IrO6 octahedra or increased orbital overlap. Here, the authors analyze the origin of the magnetic response observed in Sr2YIrO6 and reveal that in this case neither volume contraction nor structural distortions are sufficient to cause any change in the magnetic state of the Ir5+ ions.

Unexpected hybridization between the main band and the superstructure band in the Bi2Sr2CaCu2O8+δ (Bi2212) superconductor is revealed by high-resolution laser-based angle-resolved photoemission measurements. It can be understood by considering the selective hybridization of bands from the bilayer splitting in Bi2212. These observations indicate that the origin of the superstructure bands is intrinsic to the CuO2 planes. Understanding the physical properties and superconductivity in Bi2212 needs consideration of the complete Fermi surface topology, involving the main bands, the superstructure bands, and their interactions.
