Possible Pressure-Induced Charge-Density Wave Quantum Critical Point In Lupd2in

We investigated the effect of application of hydrostatic pressure on the charge-density wave (CDW) state in Lu(Pt1-xPdx)(2)In by electrical-resistivity measurements. In Lu(Pt0.7Pd0.3)(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 LuPd2In around p approximate to 20 GPa.
