Condensed Matter and Materials Physics

Condensed Matter Physics includes solid-state physics and the study of liquids and soft materials. As the largest field within physics, it includes a wide range of topics such as semiconductors, metals, magnets, superconductors, polymers, and biological systems. Our theorists and experimentalists explore quantum-mechanical phenomena including: semiconductor spintronics and optoelectronics, superconductivity, magnetism, and strong light-matter coupling; and they explore soft-condensed-matter topics such as the melting phase transition and colloidal crystals. Students attend a weekly Materials Physics/Solid State Physics seminar.

Our department has recently expanded its size in the area of condensed matter. We now have more than eleven labs filled with state-of-the-art equipment, and we offer students a wide range of thesis projects. Our theoretical group frequently publishes joint papers with our experimentalists. We give numerous invited talks at national and international conferences. Specialized courses are offered bi-annually, including Semiconductor Physics, Solid State Physics, Quantum Electronics, Laser Principles, and Nonlinear Optics. Students give talks at national and international meetings. There is a particularly wide job market for students trained in this area, with excellent opportunities in industry, government labs, and academia. Our strong research collaboration with industrial partners aids students in finding jobs.
