Beyond-Luttinger-liquid thermodynamics of a one-dimensional Bose gas with repulsive contact interactions
We present a thorough study of the thermodynamics of a one-dimensional repulsive Bose gas, focusing in particular on corrections beyond the Luttinger-liquid description. We compute the chemical potential, pressure, and contact as a function of temperature and gas parameter with an exact thermal Beth...
