Perturbative instability towards delocalization at phase transitions between MBL phases
Sanjay Moudgalya, David A. Huse, Vedika Khemani
We examine the stability of marginally Anderson localized phase transitions between localized phases to the addition of many-body interactions, focusing in particular on the spin-g…
Eta-Pairing in Hubbard Models: From Spectrum Generating Algebras to Quantum Many-Body Scars
Sanjay Moudgalya, Nicolas Regnault, B. Andrei Bernevig
We revisit the -pairing states in Hubbard models and explore their connections to quantum many-body scars to discover a universal scars mechanism. -pairing occurs due to an a…
Large Classes of Quantum Scarred Hamiltonians from Matrix Product States
Sanjay Moudgalya, Edward O'Brien, B. Andrei Bernevig +2
Motivated by the existence of exact many-body quantum scars in the AKLT chain, we explore the connection between Matrix Product State (MPS) wavefunctions and many-body quantum scar…
Quantum Many-body Scars in a Landau Level on a Thin Torus
Sanjay Moudgalya, B. Andrei Bernevig, Nicolas Regnault
We study a kinetically constrained pair hopping model that arises within a Landau level in the quantum Hall effect. At filling , the model exactly maps onto the so-called "…
An Extension of ETH to Non-Equilibrium Steady States
Sanjay Moudgalya, Trithep Devakul, D. P. Arovas +1
We extend the notion of the Eigenstate Thermalization Hypothesis (ETH) to Open Quantum Systems governed by the Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) Master Equation. We pres…
Operator Spreading in Quantum Maps
Sanjay Moudgalya, Trithep Devakul, C. W. von Keyserlingk +1
Operators in ergodic spin-chains are found to grow according to hydrodynamical equations of motion. The study of such operator spreading has aided our understanding of many-body qu…
