Wall tension of a Bose-Einstein condensate: Effects of quantum fluctuations and finite-range interactions
Pham Duy Thanh, Nguyen Van Thu
We investigate the effects of quantum fluctuations (QFs) and finite-range interatomic interactions on the ground state and wall tension of a Bose-Einstein condensate (BEC) at zero…

Nonuniversal beyond-LHY corrections to thermodynamic properties of a weakly interacting Bose gas
Pham Duy Thanh, Nguyen Van Thu
We investigate the effects of finite-range interatomic interactions on the equation of state (EoS) of a weakly interacting Bose gas. Within the Cornwall-Jackiw-Tomboulis effective…

Transition temperature and thermodynamic properties of homogeneous weakly interacting Bose gas in self-consistent Popov approximation
Nguyen Van Thu, Pham Duy Thanh, Lo Thi Thuy
This study utilizes the Cornwall-Jackiw-Tomboulis effective action approach combined with variational perturbation theory to investigate the relative shift in the transition temper…
