Correlated Electrons Under Extreme Pressure
Recently, we have investigated strongly correlated materials under pressure, scanning for phase transitions using Raman spectroscopy (inelastic light scattering) and X-Ray diffraction. With diamond anvil cells (DAC), single crystal samples can be placed under pressures of 500,000 atmospheres and more, depending on the sample area. Investigating pressure-driven phase transitions in strongly correlated electron materials allows for insights not attainable with the more widespread variable, chemical doping.
