On the hydrodynamics of unstable excitations

Journal of High Energy Physics, 2020
The generalized hydrodynamic (GHD) approach has been extremely successful in describing the out-of-equilibrium properties of a great variety of integrable many-body quantum systems.

Conformal bootstrap deformations

Journal of High Energy Physics, 2022
We explore the space of extremal functionals in the conformal bootstrap. By recasting the bootstrap problem as a set of non-linear equations parameterized by the CFT data, we find an efficient algorithm for converging to the extremal solution ...

The complex sinh-Gordon model: form factors of descendant operators and current-current perturbations

Journal of High Energy Physics, 2019
We study quasilocal operators in the quantum complex sinh-Gordon theory in the form factor approach. The free field procedure for descendant operators is developed by introducing the algebra of screening currents and related algebraic objects.

Logarithmic negativity in quantum Lifshitz theories

Journal of High Energy Physics, 2020
We investigate quantum entanglement in a non-relativistic critical system by calculating the logarithmic negativity of a class of mixed states in the quantum Lifshitz model in one and two spatial dimensions.

BPS skyrmions of generalized Skyrme model in higher dimensions

Journal of High Energy Physics, 2022
In this work we consider the higher dimensional Skyrme model, with spatial dimension d > 3, focusing on its BPS submodels and their corresponding features.

Renormalization of scalar field theories in rational spacetime dimensions [PDF]

, 2020
We renormalize various scalar field theories with a ϕn self interaction such as n= 5 , 7 and 9 in their respective critical dimensions which are non-integer.

Anomalies in field theories with extra dimensions [PDF]

, 2004
We give an overview of the issue of anomalies in field theories with extra dimensions. We start by reviewing in a pedagogical way the computation of the standard perturbative gauge and gravitational anomalies on non-compact spaces, using Fujikawa's ...

Type II defects revisited

Journal of High Energy Physics, 2018
Energy and momentum conservation in the context of a type II, purely transmitting, defect, within a single scalar relativistic two-dimensional field theory, places a severe constraint not only on the nature of the defect but also on the potentials for ...

p-form electrodynamics as edge modes of a topological field theory

Journal of High Energy Physics, 2023
p-form electrodynamics in d ≥ 2 dimensions is shown to emerge as the edge modes of a topological field theory with a precise set of boundary conditions, through the Hamiltonian reduction of its action.

Lower Bound on the Energy Density in Classical and Quantum Field Theories [PDF]

, 2017
A novel method for deriving energy conditions in stable field theories is described. In a local classical theory with one spatial dimension, a local energy condition always exists.
