Universally diverging Grueneisen parameter and the magnetocaloric effect close to quantum critical points

Lijun Zhu, Markus Garst, Achim Rosch +1

At a generic quantum critical point, the thermal expansion is more singular than the specific heat . Consequently, the "Grüneisen ratio'', $\GE=α/c_p$, diverges. When scal…
