Rotational Grüneisen ratio: a probe for quantum criticality in anisotropic systems

Shohei Yuasa, Yohei Kono, Yuta Ozaki +4

The Grüneisen ratio $\hat{I}“$ and its magnetic analog, the magnetic Grüneisen ratio $\hat{I}{“}_H$, are powerful probes to study the nature of quantum phase transitions. Here, we propose a Gr…
