====== Seminar on Gravity ======
We will use the book Feynman Lectures on Gravitation and as a supplement T.Zee, Quantum field theory in a nutshell.
   - Graviton Exchange, Propagator (Feynman 3.1-3.4): Michael (special date Wed. 11 December, 10-11)
  -   Free graviton Lagrangian (Feynman 3.5-4.2, Zee ...): Lukas (16. January)
  -   Scalar-graviton/photon-graviton interaction (Feynman 4.3-4.5, Zee...): Martin (30 January)
  - Gravity and point particles, planet orbits, perihelion precession (Feynman 4.6-5.1): Markus (13 February)
  - Self-interaction of gravitons (Feynman 5.5-6.2),  full Lagrangian (Feynman 6.3-6.5):  Heidi and Christian (27 February and 13 March)


Possible future topics could be the papers by Weinberg: [[ http://dx.doi.org/10.1103/PhysRev.138.B988|Photons and Gravitons in Perturbation Theory: Derivation of Maxwell's and Einstein's Equations]] and [[http://dx.doi.org/10.1103/PhysRev.140.B516 |Infrared Photons and Gravitons]]
