Interaction-rotation driven localization-delocalization of eigenstate in Fock space: An exact diagonalization study on trapped Bose gas
Mohd Talib, M. A. H. Ahsan
We investigate the localization-delocalization transition and entanglement structure in a finite system of interacting bosons in non-rotating and rotating cases. The many-body eige…

Spectral form factor and power spectrum for trapped interacting rotating bosons: Crossover from integrability to quantum chaos
Mohd Talib, M. A. H. Ahsan
The emergence of quantum chaos in a system of trapped interacting bosons with externally impressed rotation is studied through spectral form factor (SFF) and power spectrum using e…

Exact diagonalization study of energy level statistics in harmonically confined interacting bosons
Mohd Talib, M. A. H. Ahsan
We present an exact diagonalization study of the spectral properties of bosons harmonically confined in a quasi-2D plane and interacting via repulsive Gaussian potential. We consid…
