Title:<\/strong> The coset construction for non-equilibrium systems<\/p>\n\n\n\n

Abstract<\/strong>:  I will present a systematic coset construction of non-equilibrium effective field theories (EFTs) governing the long-distance and late-time dynamics of relativistic, finite-temperature condensed matter systems. This non-equilibrium coset construction makes significant advances beyond more standard coset constructions in that it takes advantage of recently-developed techniques, which allow the formulation of non-equilibrium effective actions that account for quantum and thermal fluctuations as well as dissipation. Because these systems exist at finite temperature, the EFTs live on the closed-time-path of the Schwinger-Keldysh contour. As an illustritive example, we will focus manily on the construction of the EFT for finite-temperatrue solds, though we will comment on how this coset method can be used to construct EFTs for a wide range of condensed matter systems.<\/p>\n<\/div><\/div>\n\n\n
