Quantum phases of disordered three-dimensional Majorana-Weyl fermions
Justin H. Wilson, J. H. Pixley, Pallab Goswami +1
The gapless Bogoliubov-de Gennes (BdG) quasiparticles of a clean three dimensional spinless superconductor provide an intriguing example of a thermal Hall semimetal (ThS…
Intrinsic decoherence in isolated quantum systems
Yang-Le Wu, Dong-Ling Deng, Xiaopeng Li +1
We study the intrinsic, disorder-induced decoherence of an isolated quantum system under its own dynamics. Specifically, we investigate the characteristic time scale (i.e., the dec…
Machine Learning Topological States
Dong-Ling Deng, Xiaopeng Li, S. Das Sarma
Artificial neural networks and machine learning have now reached a new era after several decades of improvement where applications are to explode in many fields of science, industr…
Lyapunov Exponent and Out-of-Time-Ordered Correlator's Growth Rate in a Chaotic System
Efim B. Rozenbaum, Sriram Ganeshan, Victor Galitski
It was proposed recently that the out-of-time-ordered four-point correlator (OTOC) may serve as a useful characteristic of quantum-chaotic behavior, because in the semi-classical l…
Logarithmic Entanglement Lightcone in Many-Body Localized Systems
Dong-Ling Deng, Xiaopeng Li, J. H. Pixley +2
We theoretically study the response of a many-body localized system to a local quench from a quantum information perspective. We find that the local quench triggers entanglement gr…
Uncovering the hidden quantum critical point in disordered massless Dirac and Weyl semi-metals
J. H. Pixley, David A. Huse, S. Das Sarma
We study the properties of the avoided or hidden quantum critical point (AQCP) in three dimensional Dirac and Weyl semi-metals in the presence of short range potential disorder. By…
Superuniversality of topological quantum phase transition and global phase diagram of dirty topological systems in three dimensions
Pallab Goswami, Sudip Chakravarty
The quantum phase transition between two clean, non interacting topologically distinct gapped states in three dimensions is governed by a massless Dirac fermion fixed point, irresp…
Note on "Diffusive quantum criticality in three-dimensional disordered Dirac semimetals"
Bitan Roy, S. Das Sarma
We correct erroneous conclusions from Ref.[1] regarding the values of various critical exponents, calculated to the two-loop order, and argue that -expansion near two spatial di…
Dynamical Localization of Coupled Relativistic Kicked Rotors
Efim B. Rozenbaum, Victor Galitski
A periodically driven rotor is a prototypical model that exhibits a transition to chaos in the classical regime and dynamical localization (related to Anderson localization) in the…
Rare region induced avoided quantum criticality in disordered three-dimensional Dirac and Weyl semimetals
J. H. Pixley, David A. Huse, S. Das Sarma
We numerically study the effect of short ranged potential disorder on massless noninteracting three-dimensional Dirac and Weyl fermions, with a focus on the question of the propose…
