Stefan Kehrein

Professor Stefan Kehrein is a faculty member at the Institute for Theoretical Physics, University of Göttingen, where he leads research on quantum many-body systems. His work bridges fundamental physics and practical applications, with focus areas in non-equilibrium quantum dynamics, entanglement properties, and connections to black holes and topological materials.

His research explores quantum entanglement in non-equilibrium systems, particularly the analytical and numerical study of Page curves, quantum phase transitions, and photoexcited materials. Recent publications highlight his contributions to understanding entanglement entropy dynamics and thermalization in closed quantum systems like the Sachdev-Ye-Kitaev model.

• Entanglement dynamics and Page curves (2024 Phys. Rev. B paper)
• Thermalization in thermodynamic limits (2024 arXiv preprint)
• Generalizations to non-integrable systems (2025 arXiv preprints)

He maintains an active research blog discussing topics such as the microscopic mechanism of light propagation in matter (Ewald-Oseen extinction theorem) and the philosophical foundations of quantum mechanics. His group employs both analytical and numerical techniques to tackle challenging problems in quantum many-body physics.
