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…
Effect of nonzero temperature to condensed fraction of a homogeneous dilute weakly interacting Bose gas
Nguyen Van Thu, Pham Duy Thanh
We investigate the effect of non-zero temperature to the condensate fraction of a homogeneous dilute weakly interacting Bose gas in very low-temperature region. Within inproved Har…
Critical temperature and thermodynamic properties of a homogeneous dilute weakly interacting Bose gas within the improved Hartree-Fock approximation at finite temperature
Nguyen Van Thu, Pham Duy Thanh
By means of Cornwall-Jackiw-Tomboulis effective action approach we investigate a homogeneous dilute weakly interacting Bose gas at finite temperature in vicinity of critical region…
