Building a Hamiltonian for spinning bodies in curved space-time — •Vojtěch Witzany — ZARM, Universität Bremen, Am Fallturm 2, 28359 Bremen, Germany

The motion of bodies smaller than the curvature scale of the background space-time can be effectively described by a multipolar formalism. Several Hamiltonians for this mode of motion were proposed, but they lack generality and theoretical foundation. In this talk, I show how to construct a set of fundamental Poisson brackets and a Hamiltonian for the multipolar body from its governing field theory.
