A quantum critical point (QCP) describes a phase change independent of thermal fluctuations and instead can be driven by chemical or hydrostatic pressure. Here, the authors investigate by X-ray diffraction the evolution of the charge density wave in 2H-TaSe2 as a function of pressure and demonstrate how it is intertwined with a QCP and the superconducting phase of the system.
