Using the Bethe ansatz solution, we analytically study expansionary, magnetic, and interacting Grüneisen parameters (GPs) for one-dimensional (1D) Lieb-Liniger and Yang-Gaudin models. These different GPs elegantly quantify the dependence of characteristic energy scales of these quantum gases on the volume, the magnetic field, and the interaction strength, revealing the caloric effects resulting from the variations of these potentials. The obtained GPs further confirm an identity which is...[Show more]
