Evidence of a structural quantum critical point in (CaSr)RhSn from a lattice dynamics study
Y. W. Cheung, Y. J. Hu, M. Imai +11
Approaching a quantum critical point (QCP) has been an effective route to stabilize superconductivity. While the role of magnetic QCPs has been extensively discussed, similar explo…

Soft phonon modes in the vicinity of the structural quantum critical point
Y. J. Hu, Y. W. Cheung, W. C. Yu +5
The quasi-skutterudite superconductors Sn (=Sr, Ca; =Ir, Rh, Co) are highly tunable featuring a structural quantum critical point. We construct a temperature-l…

Second-order Structural Transition in Superconductor LaCoSn
Y. W. Cheung, J. Z. Zhang, J. Y. Zhu +10
The quasi-skutterudite superconductor LaCoSn undergoes a phase transition at K. By measuring the temperature dependence of heat capacity, electrical resist…
