Welcome to Our Lab

Complex Electrons under Pressure(CEP) Group

Laboratory for Complex Electrons under Pressure (CEP)

Interactions between electrons in complex materials create a wealth of correlated phenomena such as superconductivity, magnetism, or quantum criticality. The ground states of these materials can be induced or effectively tuned by the application of pressure. The Laboratory for CEP uses and develops many high-pressure techniques such as transport, Raman scattering, X-ray diffraction, and neutron to explore their structure, magnetic, optical, and bonding properties. Work in our laboratory seeks to unravel the microscopic mechanisms underlying the complex correlated electrons. We analyze and interpret the resulting data in close collaboration between experimentalists and theorists.

The current research focuses on

Superconductivity in elements, alloys, organic systems, cuprate and iron-based systems.

Multifunction materials exhibiting magnetoelectric coupling or thermoelectricity.
