Systematic study of the Grüneisen ratio near quantum critical points
At any pressure-sensitive quantum critical point (QCP), the volume thermal expansion coefficient is more singular than the specific heat. Consequently, the resulting critical Grüneisen ratio Γcr~βcr/Ccr, where βcr and Ccr denote the thermal expansion and specific heat after subtraction of non-critic...
