[HTML][HTML] Observation of a large-gap topological-insulator class with a single Dirac cone on the surface

Y Xia, D Qian, D Hsieh, L Wray, A Pal, H Lin, A Bansil… - Nature physics, 2009 - nature.com
Recent experiments and theories have suggested that strong spin–orbit coupling effects in
certain band insulators can give rise to a new phase of quantum matter, the so-called …

Many-body localization phase transition

A Pal, DA Huse - Physical review b, 2010 - APS
We use exact diagonalization to explore the many-body localization transition in a random-
field spin-1/2 chain. We examine the correlations within each many-body eigenstate, looking …

Observation of unconventional quantum spin textures in topological insulators

D Hsieh, Y Xia, L Wray, D Qian, A Pal, JH Dil… - Science, 2009 - science.org
A topologically ordered material is characterized by a rare quantum organization of
electrons that evades the conventional spontaneously broken symmetry–based …

Localization-protected quantum order

DA Huse, R Nandkishore, V Oganesyan, A Pal… - Physical Review B, 2013 - APS
Closed quantum systems with quenched randomness exhibit many-body localized regimes
wherein they do not equilibrate, even though prepared with macroscopic amounts of energy …

Measurement-induced entanglement transitions in many-body localized systems

O Lunt, A Pal - Physical Review Research, 2020 - APS
The resilience of quantum entanglement to a classicality-inducing environment is tied to
fundamental aspects of quantum many-body systems. The dynamics of entanglement has …

Energy transport in disordered classical spin chains

V Oganesyan, A Pal, DA Huse - Physical Review B, 2009 - APS
We present a numerical study of the diffusion of energy at high temperature in strongly
disordered chains of interacting classical spins evolving deterministically. We find that …

Signatures of the many-body localized regime in two dimensions

TB Wahl, A Pal, SH Simon - Nature Physics, 2019 - nature.com
Lessons from Anderson localization highlight the importance of the dimensionality of real
space for localization due to disorder. More recently, studies of many-body localization have …

Measurement-induced criticality and entanglement clusters: A study of one-dimensional and two-dimensional Clifford circuits

O Lunt, M Szyniszewski, A Pal - Physical Review B, 2021 - APS
Entanglement transitions in quantum dynamics present a novel class of phase transitions in
nonequilibrium systems. When a many-body quantum system undergoes unitary evolution …

Exact three-colored quantum scars from geometric frustration

K Lee, R Melendrez, A Pal, HJ Changlani - Physical Review B, 2020 - APS
Nonequilibrium properties of quantum materials present many intriguing properties, among
them athermal behavior, which violates the eigenstate thermalization hypothesis. Such …

Efficient representation of fully many-body localized systems using tensor networks

TB Wahl, A Pal, SH Simon - Physical Review X, 2017 - APS
We propose a tensor network encoding the set of all eigenstates of a fully many-body
localized system in one dimension. Our construction, conceptually based on the ansatz …
