Possible Pressure-Induced Charge-Density Wave Quantum Critical Point in LuPd2In

Abstract

We investigated the effect of application of hydrostatic pressure on the charge-density wave (CDW) state in Lu(Pt${}_{1-x}$Pd${}_x$)${}_2$In by electrical-resistivity measurements. In Lu(Pt${}_{0.7}$Pd${}_{0.3}$)${}_2$In we find an increase of the CDW transition temperature upon application of pressure, which is not expected based on simple volume arguments, but in line with results of a theoretical work by Kim et al. [Phys. Rev. Lett. 125, 157001 (2020).]. Combining experimental and theoretical results suggests the existence of a CDW quantum critical point in stoichiometric LuPd${}_2$In around $p\approx 20$ GPa.
