This course introduces modern field-theoretical approaches to non-equilibrium systems. Through practical examples from quantum gases/optics, we construct the Keldysh formalism and explore the connections to classical stochastic field theory, hydrodynamics, and the dynamics of phase transitions.



non-equilibrium; field theory; driven-dissipative dynamics; open quantum many-body systems; stochastic field theory; Schwinger-Keldysh formalism

Learning Prerequisites

Required courses

Prior knowledge of (second-quantized) quantum mechanics is required and very basic knowledge of field theory will be helpful (but not necessary)
