Distinguishing localization from chaos: challenges in finite-size systems
D. A. Abanin, J. H. Bardarson, G. De Tomasi +7
We re-examine attempts to study the many-body localization transition using measures that are physically natural on the ergodic/quantum chaotic regime of the phase diagram. Using s…
A Brief History of Time Crystals
Vedika Khemani, Roderich Moessner, S. L. Sondhi
The idea of breaking time-translation symmetry has fascinated humanity at least since ancient proposals of the perpetuum mobile. Unlike the breaking of other symmetries, such as sp…
Localization from Hilbert space shattering: from theory to physical realizations
Vedika Khemani, Michael Hermele, Rahul M. Nandkishore
We show how a finite number of conservation laws can globally `shatter' Hilbert space into exponentially many dynamically disconnected subsectors, leading to an unexpected dynamics…
Asymmetric butterfly velocities in 2-local Hamiltonians
Yong-Liang Zhang, Vedika Khemani
The speed of information propagation is finite in quantum systems with local interactions. In many such systems, local operators spread ballistically in time and can be characteriz…
Prethermalization without temperature
David J. Luitz, Roderich Moessner, S. L. Sondhi +1
While a clean driven system generically absorbs energy until it reaches `infinite temperature', it may do so very slowly exhibiting what is known as a prethermal regime. Here, we s…
Local constraints can globally shatter Hilbert space: a new route to quantum information protection
Vedika Khemani, Rahul Nandkishore
We show how local constraints can globally "shatter" Hilbert space into subsectors, leading to an unexpected dynamics with features reminiscent of both many body localization and q…
