Evidence of a structural quantum critical point in (Ca $_{x}$ Sr $_{1 - x}$ ) $_{3}$ Rh $_{4}$ Sn $_{13}$ 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…

Pressure-induced enhancement of non-polar to polar transition temperature in metallic LiOsO $_{3}$

Esteban I. Paredes Aulestia, Yiu Wing Cheung, Yue-Wen Fang +5

LiOsO $_{3}$ undergoes a continuous transition from a centrosymmetric $R 3 ˉ c$ structure to a polar $R 3 c$ structure at $T_{s} = 140$ ~K. By combining transport measurements and first-pr…

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 $A_{3} T_{4}$ Sn $_{13}$ ( $A$ =Sr, Ca; $T$ =Ir, Rh, Co) are highly tunable featuring a structural quantum critical point. We construct a temperature-l…

Second-order Structural Transition in Superconductor La $_{3}$ Co $_{4}$ Sn $_{13}$

Y. W. Cheung, J. Z. Zhang, J. Y. Zhu +10

The quasi-skutterudite superconductor La $_{3}$ Co $_{4}$ Sn $_{13}$ undergoes a phase transition at $T^{*} = 152$ K. By measuring the temperature dependence of heat capacity, electrical resist…
