Holographic open quantum systems: toy models and analytic properties of thermal correlators
Journal of High Energy Physics, 2023 We present a unified picture of open quantum systems, the theory of a system probing a noisy thermal environment, distilling lessons learnt from previous holographic analyses.

Thermalization and chaos in a 1+1d QFT
Journal of High Energy Physics, 2023 We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. We find that our eigenstate spectrum satisfies Wigner-Dyson statistics and that the coefficients describing eigenstates in our basis satisfy ...

Time evolution of correlation functions in non-equilibrium field theories [PDF]
Physics Letters B, 1998 We investigate the non-equilibrium properties of an N-component scalar field theory. The time evolution of the correlation functions for an arbitrary ensemble of initial conditions is described by an exact functional differential equation. In leading order in the 1/N expansion the system can be understood in terms of infinitely many conserved ...

Stochastic Density Functional Theory on Lane Formation in Electric-Field-Driven Ionic Mixtures: Flow-Kernel-Based Formulation [PDF]
, 2022 Simulation and experimental studies have demonstrated non-equilibrium ordering in driven colloidal suspensions: with increasing driving force, a uniform colloidal mixture transforms into a locally demixed state characterized by the lane formation or the ...

Thermal three-point functions from holographic Schwinger-Keldysh contours
Journal of High Energy Physics, 2023 We compute fully retarded scalar three-point functions of holographic CFTs at finite temperature using real-time holography. They describe the nonlinear response of a holographic medium under scalar forcing, and display single and higher-order poles ...

Cumulants in perturbation expansions for non-equilibrium field theory [PDF]
Nuclear Physics A, 1996 Abstract The formulation of perturbation expansions for a quantum field theory of strongly interacting systems in a general non-equilibrium state is discussed. Non-vanishing initial correlations are included in the formulation of the perturbation expansion in terms of cumulants.

An intuitive construction of modular flow
Journal of High Energy Physics, 2023 The theory of modular flow has proved extremely useful for applying thermodynamic reasoning to out-of-equilibrium states in quantum field theory. However, the standard proofs of the fundamental theorems of modular flow use machinery from Fourier analysis
