Theoretical Quantum Science Group
Overview
Our theoretical quantum science group is based at Oklahoma State University in Stillwater, OK. We are working on fundamental questions in quantum many-body physics, with a strong focus on non-equilibrium dynamics and quantum information. We develop and apply advanced numerical methods to study dynamics of entanglement, transport phenomena, and phase transitions in driven quantum systems. A key theme of our research is the connection between fundamental theory and experimental platforms, such as ultracold atoms and quantum simulators.

Alumni
- Arman Duha, PhD (2025) — Thesis: “Non-Equilibrium Entanglement Dynamics and Transport in Engineered Quantum Systems.”
- Samuel E. Begg, PhD — Postdoctoral researcher. Research focus: non-equilibrium dynamics, squeezing phase transitions, quantum Monte Carlo methods. Samuel joined the group in 2024 after completing his PhD at King’s College London. He worked on phase transitions in driven quantum systems and developing novel numerical methods for quantum dynamics. He recently moved to University of Texas at Dallas as a postdoctoral researcher.
