Thermofield Dynamics and Gravity

Parameswaran Nair


I will discuss thermofield dynamics in terms of a path-integral using coherent states, and also in terms of a field theoretic formulation on a manifold ${\mathcal M} \times {\tilde{\mathcal M}}$ where the two components have opposite orientation. As an application, a formulation of gravitational dynamics for noncommutative geometry using thermofield dynamics, with a doubling the Hilbert space modeling the noncommutative space will be considered. For 2+1 dimensions, since ${\mathcal M}$ and ${\tilde{\mathcal M}}$ have the opposite orientation, the commutative limit leads to the Einstein-Hilbert action as the difference of two Chern-Simons actions.
