Thermodynamics and Tomonaga-Luttinger liquid behavior of the quantum 1D hard rod model
The quantum 1D hard rod model shows Tomonaga-Luttinger liquid behavior across wide parameter ranges at zero and finite temperature, with thermodynamic quantities deviating from the Lieb-Liniger model at high densities, validated by analytical and numerical methods.
