Nonuniversal beyond-LHY corrections to thermodynamic properties of a weakly interacting Bose gas

Nguyen Van Thu, Pham Duy Thanh

Finite-range interactions produce nonuniversal corrections to the equation of state and thermodynamic properties of a weakly interacting Bose gas at zero temperature.

Claims

C1strongest claim

Within the Cornwall-Jackiw-Tomboulis effective action approach, we show that finite-range effects influence not only the EoS but also the thermodynamic properties of the system at zero temperature, leading to nonuniversal behavior.

C2weakest assumption

That the Cornwall-Jackiw-Tomboulis effective action, applied in the weakly interacting regime, correctly isolates finite-range corrections without higher-order terms or uncontrolled approximations that would restore universality.

C3one line summary

Finite-range effects produce nonuniversal beyond-LHY corrections to the zero-temperature thermodynamics of a weakly interacting Bose gas.
