Quantization of the Free Electromagnetic Field: Photons ...

a gauge symmetry. They can be shifted using some guage transformation (f) without changing the electric and magnetic fields: A00 1 c ∂f ∂t (4) The Euler-Lagrange variation of the Lagrangian w.r.t the coordinates q= (Φ,A x,A y,A z) gives back Maxwell’s equations. Recall Euler-Lagrange equation and try it as a practice problem in ...

MIRROR SYMMETRY - Clay Mathematics Institute

Gromov-Witten invariants in genus zero, as is predicted by mirror symmetry. Part 5 is devoted to advanced topics in mirror symmetry, including the role of D-branes in the context of mirror symmetry, and some of their applications in physics and mathematics: topological strings and large N Chern-Simons theory;
