Anomalous energy correlations and spectral form factor in the nonergodic phase of the -ensemble
Basudha Roy, Adway Kumar Das, Anandamohan Ghosh +1
The -ensemble is a prototypical model of a single particle system on a one-dimensional disordered lattice with inhomogeneous nearest neighbor hopping. Corresponding nonergodic p…
Spectral statistics, non-equilibrium dynamics and thermalization in random matrices with global -symmetry
Adway Kumar Das
symmetry is ubiquitous in quantum mechanics where it drives various phase transitions and emergent physics. The role of symmetry in the thermalization…
Proposal for many-body quantum chaos detection with single-site measurements
Isaías Vallejo-Fabila, Adway Kumar Das, Sayan Choudhury +1
We demonstrate that the long-time dynamics of an observable associated with a single lattice site is sufficient to determine whether a many-body quantum system exhibits level stati…
Spectral form factor and energy correlations in banded random matrices
Adway Kumar Das, Anandamohan Ghosh, Lea F. Santos
Banded random matrices were introduced as a more realistic alternative to full random matrices for describing the spectral statistics of heavy nuclei. Initially considered by Wigne…
Emergent multifractality in power-law decaying eigenstates
Adway Kumar Das, Anandamohan Ghosh, Ivan M. Khaymovich
Eigenstate multifractality is of significant interest with potential applications in various fields of quantum physics. Most of the previous studies concentrated on fine-tuned quan…
