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…
Stability of attractive bosonic cloud with van der Waals interaction
Anindya Biswas, Tapan Kumar Das, Luca Salasnich +1
We investigate the structure and stability of Bose-Einstein condensate of Li atoms with realistic van der Waals interaction by using the potential harmonic expansion method.…
Thermodynamic properties of ultracold Bose gas: transition exponents and universality
Sanchari Goswami, Tapan Kumar Das, Anindya Biswas
We report exact numerical calculation of chemical potential, condensate fraction and specific heat of non-interacting bosons confined in an isotropic harmonic oscillator trap i…
Pair-correlation properties and momentum distribution of finite number of interacting trapped bosons in three dimension
Anindya Biswas, Barnali Chakrabarti, Tapan Kumar Das
We study the ground state pair-correlation properties of a weakly interacting trapped Bose gas in three dimension by using a correlated many-body method. Use of the van der Waals i…
