Stephan Haas

Stephan Haas received his PhD at the National High Magnetic Field Laboratory in 1998 and has been a professor at USC since 1998, where he chaired the Physics & Astronomy Department since 2015. Stephan Haas is a theoretical condensed matter physicist, working on the properties of quantum many-body systems. He is an expert in material realistic simulations, using a wide array of state-of-the-art numerical tools, including density functional theory, Quantum Monte Carlo, and numerical renormalization group techniques. Recently, he has focused on light-matter interactions, quantum phase diagrams, quantum phase transitions, quantum dynamics, thermodynamics and transport. Specifically, he has studied the interplay of screening and superconductivity in low-dimensional materials, valley plasmonics, and topological protection mechanisms.
