Prof. Dr. Peter P. Orth
I am a theoretical condensed matter physicist working on understanding and predicting electronic properties of quantum materials. I place an emphasis on exploring their nonlinear response and nonequilibrium dynamics. My research interests span from correlated phenomena such as frustrated magnetism and unconventional superconductivity to magnetic topological phases and light-driven materials. To address these questions, I employ analytical field theory methods and develop quantum computing algorithms with a focus on implementations on current noisy intermediate-scale quantum hardware.
From 2021-2023, I have served as the deputy director of the U.S. Department of Energy EFRC "Center for the Advancement of Topological Semimetals", where I have focused on finding new ways to realize desired electronic band topologies by controlling magnetic order. Since 2021, I have been a co-leader in the quantum algorithm thrust of the DOE National Quantum Initiative Center on "Superconducting Quantum Materials and Systems", where I develop and implement quantum computing algorithms for many-body systems.
