Feynman rules for forced wave turbulence

Journal of High Energy Physics, 2023
It has long been known that weakly nonlinear field theories can have a late-time stationary state that is not the thermal state, but a wave turbulent state with a far-from-equilibrium cascade of energy.

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.

QFT approach to dressed particle processes in preheating and non-perturbative mechanism in kinematically-forbidden regime

Journal of High Energy Physics, 2023
We provide a quantum-field theoretic formulation of dressed particle dynamics that systematically includes particle production and scattering/decay processes in the preheating era.

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.

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

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.

Dissipation in equations of motion of scalar fields [PDF]

, 2002
The methods of non-equilibrium quantum field theory are used to investigate the possibility of representing dissipation in the equation of motion for the expectation value of a scalar field by a friction term, such as is commonly included in ...

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 ...
