Daniel Braak

Dr. Daniel Braak is a DFG group leader at the Theoretical Physics III chair within the Institute of Physics at the University of Augsburg. His research focuses on exact solutions in quantum optics, topological condensed matter systems, and quantum thermodynamics.

Research Interests

• Strong light-matter interaction
• Integrable quantum systems
• Quantum integrability and spectral theory
• Topological properties of materials
• Quantum thermodynamics
• Quantum mechanics in Hilbert spaces of analytic functions

Grants

• Principal Investigator of the DFG-funded project Exact solutions of strongly interacting models of quantum optics (Project No. 439943572).

Publications

His recent work explores the quantum Rabi model, anisotropic two-photon systems, and nonlinear quantum dynamics, with a focus on analytical solutions, spectral collapse, and topological phase transitions. Key topics include hidden symmetries, quantum metrology, and non-reciprocal transport in solid-state systems.
