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…
