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…
Transition temperature of the homogeneous imperfect Bose gas
Nguyen Van Thu, Pham Duy Thanh
Beyond standard approaches in existing literature, we explore the relative shift in the transition temperature of a homogeneous dilute Bose gas using the Cornwall-Jackiw-Tomboulis…
