Application of pressure offers a way to continuously tune the ground state of a system across different phases realizing so-called quantum phase transitions. However, studying the order parameter is challenging because some established experimental techniques are not compatible with diamond anvil pressure cells. Here, the authors show that ultrafast pump-probe …
