On Rare Nonresonant Regions and Subdiffusive Transport in an Interacting Disordered Quantum Chain
A. Scardicchio, S. L. Sondhi
We study rare nonresonant regions in a canonical one-dimensional disordered quantum spin chain by directly implementing the iterated Schrieffer-Wolff construction underlying the re…
A comment on "Discrete time crystals: rigidity, criticality, and realizations"
Vedika Khemani, Roderich Moessner, S. L. Sondhi
The Letter by N. Y. Yao et. al. [1,2] presents three models for realizing a many-body localized discrete time-crystal (MBL DTC): a short-ranged model [1], its revised version [2],…
Many-body physics in the NISQ era: quantum programming a discrete time crystal
Matteo Ippoliti, Kostyantyn Kechedzhi, Roderich Moessner +2
Recent progress in the realm of noisy, intermediate scale quantum (NISQ) devices represents an exciting opportunity for many-body physics, by introducing new laboratory platforms w…
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…
Mott, Floquet, and the response of periodically driven Anderson insulators
Dillon T. Liu, J. T. Chalker, Vedika Khemani +1
We consider periodically driven Anderson insulators. The short time behavior for weak, monochromatic, uniform electric fields is given by linear response theory and was famously de…
Equilibration and Order in Quantum Floquet Matter
R. Moessner, S. L. Sondhi
Equilibrium theormodynamics is characterized by two fundamental ideas: thermalisation--that systems approach a late time thermal state; and phase structure--that thermal states exh…
Absolute Stability and Spatiotemporal Long-Range Order in Floquet systems
C. W. von Keyserlingk, Vedika Khemani, S. L. Sondhi
Recent work has shown that a variety of novel phases of matter arise in periodically driven Floquet systems. Among these are many-body localized phases which spontaneously break gl…
Obtaining highly-excited eigenstates of many-body localized Hamiltonians by the density matrix renormalization group
Vedika Khemani, Frank Pollmann, S. L. Sondhi
The eigenstates of many-body localized (MBL) Hamiltonians exhibit low entanglement. We adapt the highly successful density-matrix renormalization group method, which is usually use…
On the phase structure of driven quantum systems
Vedika Khemani, Achilleas Lazarides, Roderich Moessner +1
Clean and interacting periodically driven quantum systems are believed to exhibit a single, trivial "infinite-temperature" Floquet-ergodic phase. In contrast, here we show that the…
Non-local Adiabatic Response of a Localized System to Local Manipulations
Vedika Khemani, Rahul Nandkishore, S. L. Sondhi
We examine the response of a system localized by disorder to a time dependent local perturbation which varies smoothly with a characteristic timescale . We find that such a pert…
AKLT Models with Quantum Spin Glass Ground States
C. R. Laumann, S. A. Parameswaran, S. L. Sondhi +1
We study AKLT models on locally tree-like lattices of fixed connectivity and find that they exhibit a variety of ground states depending upon the spin, coordination and global (gra…
Dipolar spin correlations in classical pyrochlore magnets
S. V. Isakov, K. Gregor, R. Moessner +1
We study spin correlations for the highly frustrated classical pyrochlore lattice antiferromagnets with O(N) symmetry in the limit T->0. We conjecture that a local constraint obeye…
A Farewell to Liouvillians
Vadim Oganesyan, J. T. Chalker, S. L. Sondhi
We examine the Liouvillian approach to the quantum Hall plateau transition, as introduced recently by Sinova, Meden, and Girvin [Phys. Rev. B {\bf 62}, 2008 (2000)] and developed b…
Breakdown of Conformal Invariance at Strongly Random Critical Points
M. B. Hastings, S. L. Sondhi
We consider the breakdown of conformal and scale invariance in random systems with strongly random critical points. Extending previous results on one-dimensional systems, we provid…
