Tensor Correlators in the Schwinger - Keldysh Formalism
We express stress tensor correlators using the Schwinger-Keldysh formalism. The absence of off-diagonal counterterms in this formalism ensures that the +− and −+ correlators are free of primitive divergences. We use dimensional regularization to explicitly check this at one loop order for a massless scalar on a flat space background. We use the same procedure to show that the ++ correlator cont...
متن کاملStress Tensor Correlators in the Schwinger - Keldysh Formalism
We express stress tensor correlators using the Schwinger-Keldysh formalism. The absence of off-diagonal counterterms in this formalism ensures that the +− and −+ correlators are free of primitive divergences. We use dimensional regularization in position space to explicitly check this at one loop order for a massless scalar on a flat space background. We use the same procedure to show that the ...
متن کاملFermionic Schwinger–Keldysh Propagators from AdS/CFT
The Herzog and Son prescription [10] for computing real–time Green functions for finite temperature gauge theories from their gravity dual is generalized to fermions. These notes explain how such an extension involves properties of spinors in a curved, complexified space–time.
متن کاملSchwinger-Keldysh Propagators from AdS/CFT Correspondence
We demonstrate how to compute real-time Green’s functions for a class of finite temperature field theories from their AdS gravity duals. In particular, we reproduce the 2× 2 SchwingerKeldysh matrix propagator from a gravity calculation. Our methods should work also for computing higher point Lorentzian signature correlators. We elucidate the boundary condition subtleties which hampered previous...
متن کاملFock-Schwinger proper time formalism for p-branes1
The theory of the usual, constrained p-branes is embedded into a larger theory in which there is no constraints. In the latter theory the Fock-Schwinger proper time formalism is extended from point-particles to p-branes which can be considered as a points in an infinite dimensional space M. The quantization appears to be straightforward and elegant. The conventional p-brane states are particula...
