Distinguishability Transitions from Global Quantum Snapshots
Catherine McCarthy, Sarang Gopalakrishnan, Romain Vasseur
Quantum states generated by generic time evolution are locally featureless: local measurements return random outcomes that are identical for all states. However, global snapshots i…
Ferromagnetism from the geometry of localized wavefunctions in moiré systems
Miguel Gonçalves, Sarang Gopalakrishnan
We present a mechanism for ferromagnetism in narrow bands consisting of Anderson-localized states. We exploit single-particle localization to derive a controlled theory of exchange…
Control transition in a temporally random classical spin chain
Elisha Shmalo, J. H. Pixley, Manas Kulkarni +2
We theoretically explore a phase transition between controlled and chaotic dynamics in a classical spin chain model subject to chaotic Hamiltonian dynamics and a contractive "contr…
Detecting vortex motion through spatially correlated nonequilibrium noise
Yifan F. Zhang, Rhine Samajdar, Sarang Gopalakrishnan
Resistive transport near a superconducting phase can arise from the motion of normal-state quasiparticles or that of vortices. The conductivity alone does not distinguish between t…
Long-lived local quantum coherences from hydrodynamic large deviations
Ewan McCulloch, J. Alexander Jacoby, Sarang Gopalakrishnan
We develop a framework to describe how quantum coherences between distinct charge sectors evolve under generic charge-conserving dynamics. Our framework captures the nonperturbativ…
Anomalous Diffusion and Superdiffusion in Integrable Spin Chains via a Soliton Gas Mapping
Andrew Urilyon, Romain Vasseur, Sarang Gopalakrishnan +1
We introduce a multi-species soliton gas in which each species has a distinct effective scattering length, and the repulsive scattering shift is set by the smaller of the two colli…
