Understanding of the Temperature--Pressure Phase Diagram of $\beta$-Pyrochlore Oxides: A Role of Anhamonicity on Superconductivity

We develop a physical understanding for how anhamonicity of lattice vibration affects transition temperature, $T_{\text{c}}$, of superconductivity mediated by phonons, via specific heat measurements on $\beta$-pyrochlore oxide superconductors under high pressure and in magnetic fields. We find that...
