Strong electron correlations have been a central issue in condensed matter physics and been the cause of various electronic phenomena, such as the Mott transition, unconventional superconductivity, charge/spin ordering, magnetic phase transition, and heavy fermion behavior. In such systems, complex phenomena are arising from coupled lattice, orbital, charge and spin degrees of freedom. To understand the mechanism of phase transitions and to control the properties, it is necessary to tackle the problems with complementary experimental techniques studying both atomic and electronic structures. Pressure is a clean method to control physical properties of material without inducing inhomogeneity or disorder. The main objective of the project is to develop high-pressure DAC for transport measurement at the Institute of Physics, and apply the technique to explore novel phenomena on strongly correlated systems under extreme conditions. Especially, the pressure and temperature induced phase transitions in the strongly correlated electron systems, such as transition metal chalcogenides and rare-earth compounds, are the main research targets of the project. The mechanism of phase transitions will be studied from atomic and electronic point of views in combination with complemental experimental technique, e.g., x-ray spectroscopy and x-ray diffractions.
