Absence of disordered Thouless pumps at finite frequency
Dominik Vuina, David M. Long, Philip J. D. Crowley +1
A Thouless pump is a slowly driven one-dimensional band insulator which pumps charge at a quantised rate. Previous work showed that pumping persists in weakly disordered chains, an…
Phenomenology of the Prethermal Many-Body Localized Regime
David M. Long, Philip J. D. Crowley, Vedika Khemani +1
The dynamical phase diagram of interacting disordered systems has seen substantial revision over the past few years. Theory must now account for a large prethermal many-body locali…
Mean field theory of failed thermalizing avalanches
Philip J. D. Crowley, Anushya Chandran
We show that localization in quasiperiodically modulated, two-dimensional systems is stable to the presence of a finite density of ergodic grains. This contrasts with the case of r…
Many-Body Localization with Quasiperiodic Driving
David M. Long, Philip J. D. Crowley, Anushya Chandran
Sufficient disorder is believed to localize static and periodically-driven interacting chains. With quasiperiodic driving by incommensurate tones, the fate of this many-body lo…
A constructive theory of the numerically accessible many-body localized to thermal crossover
Philip J. D. Crowley, Anushya Chandran
The many-body localised (MBL) to thermal crossover observed in exact diagonalisation studies remains poorly understood as the accessible system sizes are too small to be in an asym…
Critical behavior of the quasi-periodic quantum Ising chain
P. J. D. Crowley, C. R. Laumann, A. Chandran
The interplay of correlated spatial modulation and symmetry breaking leads to quantum critical phenomena intermediate between those of the clean and randomly disordered cases. By p…
The quasi-periodic quantum Ising transition in 1D
P. J. D. Crowley, A. Chandran, C. R. Laumann
Unlike random potentials, quasi-periodic modulation can induce localisation-delocalisation transitions in one dimension. In this article, we analyse the implications of this for sy…
How does a locally constrained quantum system localize?
Chun Chen, Fiona Burnell, Anushya Chandran
At low energy, the dynamics of excitations of many physical systems are locally constrained. Examples include frustrated anti-ferromagnets, fractional quantum Hall fluids and Rydbe…
Thermal inclusions: how one spin can destroy a many-body localized phase
Pedro Ponte, C. R. Laumann, David A. Huse +1
Many-body localized (MBL) systems lie outside the framework of statistical mechanics, as they fail to equilibrate under their own quantum dynamics. Even basic features of MBL syste…
Localization and symmetry breaking in the quantum quasiperiodic Ising glass
Anushya Chandran, C. R. Laumann
Quasiperiodic modulation can prevent isolated quantum systems from equilibrating by localizing their degrees of freedom. In this article, we show that such systems can exhibit dyna…
Many-body localization beyond eigenstates in all dimensions
A. Chandran, A. Pal, C. R. Laumann +1
Isolated quantum systems with quenched randomness exhibit many-body localization (MBL), wherein they do not reach local thermal equilibrium even when highly excited above their gro…
Finite size scaling bounds on many-body localized phase transitions
A. Chandran, C. R. Laumann, V. Oganesyan
Quantum phase transitions are usually observed in ground states of correlated systems. Remarkably, eigenstate phase transitions can also occur at finite energy density in disordere…
A semi-classical limit for the many-body localization transition
Anushya Chandran, C. R. Laumann
We introduce a semi-classical limit for many-body localization in the absence of global symmetries. Microscopically, this limit is realized by disordered Floquet circuits composed…
Local integrals of motion and the logarithmic lightcone in many-body localized systems
Isaac H. Kim, Anushya Chandran, Dmitry A. Abanin
We propose to define full many-body localization in terms of the recently introduced integrals of motion[Chandran et al., arXiv:1407.8480], which characterize the time-averaged res…
Constructing local integrals of motion in the many-body localized phase
Anushya Chandran, Isaac H. Kim, Guifre Vidal +1
Many-body localization provides a generic mechanism of ergodicity breaking in quantum systems. In contrast to conventional ergodic systems, many-body localized (MBL) systems are ch…
Periodically driven ergodic and many-body localized quantum systems
Pedro Ponte, Anushya Chandran, Z. Papić +1
We study dynamics of isolated quantum many-body systems under periodic driving. We consider a driving protocol in which the Hamiltonian is switched between two different operators…
