Thermofield dynamics and Gravity | V.P. Nair
; | Date: |
2 Aug 2015 | Abstract: | Thermofield dynamics is presented in terms of a path-integral using coherent
states, equivalently, using a coadjoint orbit action. A field theoretic
formulation in terms of fields on a manifold ${mathcal M} imes
{ ilde{mathcal M}}$ where the two components have opposite orientation is
also presented. We propose formulating gravitational dynamics for
noncommutative geometry using thermofield dynamics, doubling the Hilbert space
modeling the noncommutative space. We consider 2+1 dimensions in some detail
and since ${mathcal M}$ and ${ ilde{mathcal M}}$ have opposite orientation,
the commutative limit leads to the Einstein-Hilbert action as the difference of
two Chern-Simons actions. | Source: | arXiv, 1508.0171 | Services: | Forum | Review | PDF | Favorites |
