Supersymmetric isospectral formalism for the calculation of near-zero energy states: application to the very weakly bound He trimer excited state
Sudip Kumar Haldar, Barnali Chakrabarti, Tapan Kumar Das
We propose a novel mathematical approach for the calculation of near-zero energy states by solving potentials which are isospectral with the original one. For any potential, famili…
Spectral fluctuation and noise in the energy level statistics of interacting trapped bosons
Kamalika Roy, Barnali Chakrabarti, Anindya Biswas +2
It has been recently shown numerically that the transition from integrability to chaos in quantum systems and the corresponding spectral fluctuations are characterized by $\frac{1}…
Dynamical features of Shannon information entropy of bosonic cloud in a tight trap
Sudip Kumar Haldar, Barnali Chakrabarti
We calculate Shannon information entropy of trapped interacting bosons in both the position and momentum spaces, and respectively. The total entropy maintains the fucti…
Energy level statistics of interacting trapped bosons
Barnali Chakrabarti, Anindya Biswas, V. K. B. Kota +2
It is an well established fact that statistical properties of energy level spectra are the most efficient tool to characterize nonintegrable quantum systems. The study of statistic…
