We investigated the effect of application of hydrostatic pressure on the charge-density wave (CDW) state in Lu(Pt_1−xPd_x)₂In by electrical-resistivity measurements. In Lu(Pt_0.7Pd_0.3)₂In 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 ≈ 20 GPa.

LuPd2In中可能的压力感应电荷密度波量子临界点

我们通过电阻率测量研究了施加静水压力对Lu（Pt _{1- x} Pd _x）₂ In中电荷密度波（CDW）状态的影响。在Lu（Pt _0.7 Pd _0.3）_2中，我们发现在施加压力时CDW转变温度会升高，这是基于简单的体积论据无法预期的，但与Kim等人的理论工作结果相符。[物理 牧师 125，157001（2020）]。结合实验和理论的结果表明在化学计量LuPd一个CDW量子临界点的存在₂在围绕p ≈为20GPa。
