Griffiths effects and slow dynamics in nearly many-body localized systems
Sarang Gopalakrishnan, Kartiek Agarwal, Eugene Demler +2
The low-frequency response of systems near a many-body localization transition can be dominated by rare regions that are locally critical or "in the other phase". It is known that,…
Quantum Control of Many-body Localized States
Soonwon Choi, Norman Y. Yao, Sarang Gopalakrishnan +1
We propose and analyze a new approach to the coherent control and manipulation of quantum degrees of freedom in disordered, interacting systems in the many-body localized phase. Ou…
Prethermal Floquet Steady States and Instabilities in the Periodically Driven, Weakly Interacting Bose-Hubbard Model
Marin Bukov, Sarang Gopalakrishnan, Michael Knap +1
We explore prethermal Floquet steady states and instabilities of the weakly interacting two-dimensional Bose-Hubbard model subject to periodic driving. We develop a description of…
Weak crystallization theory of metallic alloys
Ivar Martin, Sarang Gopalakrishnan, Eugene A. Demler
We extend the Weak Crystallization theory to the case of metallic alloys. The additional ingredient -- itinerant electrons -- generates nontrivial dependence of free energy on the…
Low-frequency conductivity in many-body localized systems
Sarang Gopalakrishnan, Markus Mueller, Vedika Khemani +3
We argue that the a.c. conductivity in the many-body localized phase is a power law of frequency at low frequency: specifically, with the exponent ap…
Limit cycle phase in driven-dissipative spin systems
Ching-Kit Chan, Tony E. Lee, Sarang Gopalakrishnan
We explore the phase diagram of interacting spin- systems in the presence of anisotropic interactions, spontaneous decay and driving. We find a rich phase diagram featuring a…
