Eigenvector Correlations Across the Localisation Transition in non-Hermitian Power-Law Banded Random Matrices
Soumi Ghosh, Manas Kulkarni, Sthitadhi Roy
The dynamics of non-Hermitian quantum systems have taken on an increasing relevance in light of quantum devices which are not perfectly isolated from their environment. The interes…
Spectral Properties of Disordered Interacting Non-Hermitian Systems
Soumi Ghosh, Sparsh Gupta, Manas Kulkarni
Non-hermitian systems have gained a lot of interest in recent years. However, notions of chaos and localization in such systems have not reached the same level of maturity as in th…
Long-ranged spectral correlations in eigenstate phases
Mahaveer Prasad, Abhishodh Prakash, J. H. Pixley +1
We study non-local measures of spectral correlations and their utility in characterizing and distinguishing between the distinct eigenstate phases of quantum chaotic and many-body…
Universal spectral form factor for many-body localization
Abhishodh Prakash, J. H. Pixley, Manas Kulkarni
We theoretically study correlations present deep in the spectrum of many-body-localized systems. An exact analytical expression for the spectral form factor of Poisson spectra can…
Non-equilibrium phase diagram of a 1D quasiperiodic system with a single-particle mobility edge
Archak Purkayastha, Abhishek Dhar, Manas Kulkarni
We investigate and map out the non-equilibrium phase diagram of a generalization of the well known Aubry-André-Harper (AAH) model. This generalized AAH (GAAH) model is known to hav…
