Semiclassical Limit of Measurement-Induced Transition in Many-Body Chaos in Integrable and Nonintegrable Oscillator Chains
Sibaram Ruidas, Sumilan Banerjee
We discuss the dynamics of integrable and nonintegrable chains of coupled oscillators under continuous weak position measurements in the semiclassical limit. We show that, in this…
Diagnostics of nonergodic extended states and many body localization proximity effect through real-space and Fock-space excitations
Nilanjan Roy, Jagannath Sutradhar, Sumilan Banerjee
We provide real-space and Fock-space (FS) characterizations of ergodic, nonergodic extended (NEE) and many-body localized (MBL) phases in an interacting quasiperiodic system, namel…
Quantum Oscillations in the Magnetisation and Density of States of Insulators
Animesh Panda, Sumilan Banerjee, Mohit Randeria
The observation of -periodic behavior in Kondo insulators SmB and YbB challenges the conventional wisdom that quantum oscillations (QO) necessarily arise from Fermi…
Scaling of Fock-space propagator and multifractality across the many-body localization transition
Jagannath Sutradhar, Soumi Ghosh, Sthitadhi Roy +3
We implement a recursive Green function method to extract the Fock space (FS) propagator and associated self-energy across the many-body localization (MBL) transition, for one-dime…
