My main working area is mathematical physics, in particular many-body quantum mechanics. More detailed research interests are:

• Quantum many-body systems
  • Non-linear Schrödinger equation
  • Derivation of effective dynamics
  • Dynamics of Bose-Einstein condensates
  • Hartree-Fock dynamics
  • Spin wave theory
  • Dynamics in the Heisenberg ferromagnet
• Relativistic quantum mechanics
  • Wave functions on space-time configurations (multi-time wave functions)
