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.

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.

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 ...

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.

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 ...

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 ...

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.

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 ...

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 ...

How planar superconductors cure their infrared divergences
Journal of High Energy Physics, 2022 Planar superconductors, emerging in thin films with thickness comparable to the superconducting coherence length, differ crucially from their bulk counterparts.
