Kadanoff-Baym equations for interacting systems with dissipative Lindbladian dynamics
Abstract
The extraordinary quantum properties of nonequilibrium systems governed by dissipative dynamics have become a focal point in contemporary scientific inquiry. The Nonequilibrium Green's Functions (NEGF) theory provides a versatile method for addressing driven {\em non-dissipative} systems, utilizing the powerful diagrammatic technique to incorporate correlation effects. We here present a second-quantization approach to the {\em dissipative} NEGF theory, reformulating Keldysh ideas to accommodate Lindbladian dynamics and extending the Kadanoff-Baym equations accordingly. Generalizing diagrammatic perturbation theory for many-body Lindblad operators, the formalism enables correlated and dissipative real-time simulations for the exploration of transient and steady-state changes in the electronic, transport, and optical properties of materials.
