Irrelevant deformations of chiral bosons
Journal of High Energy Physics, 2021 We study T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ deformations of chiral bosons using the formalism due to Sen. For arbitrary numbers of left- and right-chiral bosons, we find that the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -deformed Lagrangian ...

Lower Bound on the Energy Density in Classical and Quantum Field Theories. [PDF]
Physical Review Letters, 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.

Symmetry enhancement and duality walls in 5d gauge theories [PDF]
Journal of High Energy Physics, 2020 Gauge theories in four dimensions can exhibit interesting low energy phenomena, such as infrared enhancements of global symmetry. We explore a class of 4d N $$ \mathcal{N} $$ = 1 gauge theories arising from a construction that is motivated by duality ...

T T ¯ $$ T\overline{T} $$ deformations of non-relativistic models
Journal of High Energy Physics, 2021 The light-cone gauge approach to T T ¯ $$ T\overline{T} $$ deformed models is used to derive the T T ¯ $$ T\overline{T} $$ deformed matrix nonlinear Schrödinger equation, the Landau-Lifshitz equation, and the Gardner equation.

Quantum quench and thermalization to GGE in arbitrary dimensions and the odd-even effect
Journal of High Energy Physics, 2020 In many quantum quench experiments involving cold atom systems the post-quench phase can be described by a quantum field theory of free scalars or fermions, typically in a box or in an external potential.

Complementary projection defects and decomposition
Journal of High Energy Physics, 2021 As put forward in [1] topological quantum field theories can be projected using so-called projection defects. The projected theory and its correlation functions can be completely realized within the unprojected one.

Quantum simulation of quantum field theory in the light-front formulation [PDF]
Physical Review A, 2020 We develop quantum simulation algorithms based on the light-front formulation of relativistic quantum field theories. We analyze a simple theory in $1+1D$ and show how to compute the analogues of parton distribution functions of composite particles in ...

Entanglement entropy in warped conformal field theories [PDF]
Journal of High Energy Physics, 2015 We present a detailed discussion of entanglement entropy in (1+1)-dimensional Warped Conformal Field Theories (WCFTs). We implement the Rindler method to evaluate entanglement and Renyi entropies for a single interval and along the way we interpret our ...

T T ¯ $$ T\overline{T} $$ flow as characteristic flows
Journal of High Energy Physics, 2023 We show that method of characteristics provides a powerful new point of view on T T ¯ $$ T\overline{T} $$ -and related deformations. Previously, the method of characteristics has been applied to T T ¯ $$ T\overline{T} $$ -deformation mainly to solve ...

T T ¯ $$ T\overline{T} $$ deformations and the width of fundamental particles
Journal of High Energy Physics, 2022 We provide a simple geometric meaning for deformations of so-called T T ¯ $$ T\overline{T} $$ type in relativistic and non-relativistic systems. Deformations by the cross products of energy and momentum currents in integrable quantum field theories are ...
