Finite temperature phase diagram of the extended Bose-Hubbard model in the presence of disorder
Madhumita Kabiraj, Raka Dasgupta
We study the finite and non-zero temperature phase diagram of the Extended Bose-Hubbard Model for both pure and disordered systems. Such a system can be experimentally realized by…
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.…
Effect of realistic interatomic interactions and two-body correlation on the heat capacity of a trapped BEC
Anindya Biswas
An approximate many-body theory has been used to calculate the heat capacity and the condensate fraction of a BEC with effective repulsive interaction. The effect of interactions h…
Many-body approach to low-lying collective excitations in a BEC approaching collapse
Anindya Biswas, Tapan Kumar Das
An approximate many-body theory incorporating two-body correlations has been employed to calculate low-lying collective multipole frequencies in a Bose-Einstein condensate containi…
