Keldysh field theory for driven open quantum systems.
Recent experimental developments in diverse areas-ranging from cold atomic gases to light-driven semiconductors to microcavity arrays-move systems into the focus which are located on the interface of quantum optics, many-body physics and statistical mechanics. They share in common that coherent and driven-dissipative quantum dynamics occur on an equal footing, creating genuine non-equilibrium s...
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 کاملTensor 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 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 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 ...
