Goldstone bosons and fluctuating hydrodynamics with dipole and momentum conservation
Journal of High Energy Physics, 2023 We develop a Schwinger-Keldysh effective field theory describing the hydrodynamics of a fluid with conserved charge and dipole moments, together with conserved momentum.

Ghostbusters: unitarity and causality of non-equilibrium effective field theories [PDF]
Journal of High Energy Physics, 2020 Abstract: For a non-equilibrium physical system defined along a closed time path (CTP), a key constraint is the so-called largest time equation, which is a consequence of unitarity and implies causality. In this paper, we present a simple proof that if the propagators of a non-equilibrium effective action have the proper pole structure, the largest ...

Analogues of Non-Gibbsianness in Joint Measures of Disordered Mean Field Models [PDF]
, 2002 It is known that the joint measures on the product of spin-space and disorder space are very often non-Gibbsian measures, for lattice systems with quenched disorder, at low temperature.

Non-cancellation of the parity anomaly in the strong-field regime of QED2+1
Physics Letters B, 2020 Quantum fluctuations lead to an anomalous violation of parity symmetry in quantum electrodynamics for an even number of spatial dimensions. While the leading parity-odd electric current vanishes in vacuum, we uncover a non-cancellation of the anomaly for

Aspects of entanglement in non-local field theories with fractional Laplacian
Journal of High Energy Physics, 2022 In recent years, various aspects of theoretical models with long range interactions have attracted attention, ranging from out-of-time-ordered correlators to entanglement.

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.

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 ...
