Non-equilibrium effective field theory and second sound

Journal of High Energy Physics, 2021
We investigate the phenomenon of second sound in various states of matter from the perspective of non-equilibrium effective field theory (EFT). In particular, for each state of matter considered, we find that at least two (though sometimes multiple ...

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.

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.

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 ...

Extending the thermodynamic form factor bootstrap program: multiple particle-hole excitations, crossing symmetry, and reparameterization invariance

Journal of High Energy Physics, 2023
In this study, we further the thermodynamic bootstrap program which involves a set of recently developed ideas used to determine thermodynamic form factors of local operators in integrable quantum field theories. These form factors are essential building

Entanglement negativity and entropy in non-equilibrium conformal field theory

Nuclear Physics B, 2015
We study the dynamics of the entanglement in one-dimensional critical quantum systems after a local quench in which two independently thermalized semi-infinite halves are joined to form a homogeneous infinite system and left to evolve unitarily.
