Push-down automata as sequential generators of highly entangled states
Sarang Gopalakrishnan
We exploit the duality between quantum channels and sequentially generated states to construct families of highly entangled states that undergo phase transitions. These highly enta…
Transitions in the learnability of global charges from local measurements
Fergus Barratt, Utkarsh Agrawal, Andrew C. Potter +2
We consider monitored quantum systems with a global conserved charge, and ask how efficiently an observer ("eavesdropper") can learn the global charge of such systems from local pr…
Rare-Region Onset of Superconductivity in Granular Systems
Malcolm Durkin, Sarang Gopalakrishnan, Rita Garrido-Menacho +3
The critical behavior of disordered systems-from metals (1) to magnets (2) and superconductors (3)-is often dominated by the behavior of rare regions of a correlated phase, which c…
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…
Anomalous diffusion and Griffiths effects near the many-body localization transition
Kartiek Agarwal, Sarang Gopalakrishnan, Michael Knap +2
We explore the high-temperature dynamics of the disordered, one-dimensional XXZ model near the many-body localization (MBL) transition, focusing on the delocalized (i.e., "metallic…
Mobile magnetic impurities in a Fermi superfluid: a route to designer molecules
Sarang Gopalakrishnan, Colin V. Parker, Eugene Demler
A magnetic impurity in a fermionic superfluid hosts bound quasiparticle states known as Yu-Shiba-Rusinov (YSR) states. We argue here that, if the impurity is mobile (i.e., has a fi…
