Pressure (or strain) is the one of key external parameter used in solid state physics that can tune the material property or induce the phase transition by changing the local lattice structure. It has been widely used in transport measurement or optical spectroscopy, however, rarely applied to the electron spectroscopy especially to angle resolved photoemission spectroscopy (ARPES). Recently, number of pioneering ARPES works with uniaxial strain are reported, covering the metal-insulator transition, the topological phase transition, or the response of nematic phase upon strain. This pioneering session is designed to overviews those pioneering works and to share the related experience.
