Peter P. Orth

  • Associate Professor
I am a theoretical condensed matter physicist working on predicting and understanding the fascinating properties of quantum materials. I place an emphasis on their nonlinear response and non-equilibrium dynamics. My research interests are broad and span from exotic magnetism to unconventional superconductivity to magnetic topological phases. To address these questions, I employ analytical field theory methods and develop quantum computing algorithms for many-body models.

My work is funded by grants from the National Science Foundation (NSF), the U.S. Department of Energy (DOE) and the Research Corporation for Science Advancement via a Cottrell Scholarship.
