Condensate fraction and critical temperature of interacting Bose gas in anharmonic trap
Sudip Kumar Haldar, Barnali Chakrabarti, Satadal Bhattacharyya +1
By using a correlated many body method and using the realistic van der Waals potential we study several statistical measures like the specific heat, transition temperature and the…
Correlated many-body calculation to study characteristics of Shannon information entropy for ultracold trapped interacting bosons
Sudip Kumar Haldar, Barnali Chakrabarti, Tapan Kumar Das +1
A correlated many-body calculation is presented to characterize the Shannon information entropy of trapped interacting bosons. We reformulate the one-body Shannon information entro…
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…
Destruction of attractive bosonic cloud due to high spatial coherence in tight trap
Anindya Biswas, Barnali Chakrabarti, Tapan Kumar Das +1
We study coherence of a trapped bosonic cloud with attractive finite-range interaction in a tight harmonic trap. One-body density and pair-distribution function in the ground state…
Behavior of heat capacity of an attractive Bose-Einstein Condensate approaching collapse
Sanchari Goswami, Tapan Kumar Das, Anindya Biswas
We report calculation of heat capacity of an attractive Bose-Einstein condensate, with the number N of bosons increasing and eventually approaching the critical number Ncr for coll…
Resonance States and Quantum Tunneling of Bose Einstein condensates in a 3D shallow trap
Sudip Kumar Haldar, Barnali Chakrabarti, Tapan Kumar Das
A correlated quantum many-body method is applied to describe resonance states of atomic Bose-Einstein condensates (BEC) in a realistic shallow trap (as opposed to infinite traps co…
