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.

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.

Quantum field theory from a quantum cellular automaton in one spatial dimension and a no-go theorem in higher dimensions [PDF]

Physical Review A, 2020
It has been shown that certain quantum walks give rise to relativistic wave equations, such as the Dirac and Weyl equations, in their long-wavelength limits. This intriguing result raises the question of whether something similar can happen in the multi-particle case.

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.

Symmetry resolved entanglement of excited states in quantum field theory. Part II. Numerics, interacting theories and higher dimensions

Journal of High Energy Physics, 2022
Abstract In a recent paper we studied the entanglement content of zero-density excited states in complex free quantum field theories, focusing on the symmetry resolved entanglement entropy (SREE). By zero-density states we mean states consisting of a fixed, finite number of excitations above the ground state in an infinite-volume ...

Constraints on chiral operators in N=2 SCFTs [PDF]

, 2014
: We study certain higher-spin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality (“type A”

Off-shell CHY amplitudes and Feynman graphs

Journal of High Energy Physics, 2020
A polynomial form is established for the off-shell CHY scattering equations proposed by Lam and Yao. Re-expressing this in terms of independent Mandelstam invariants provides a new expression for the polynomial scattering equations, immediately valid off

Entanglement of harmonic systems in squeezed states

Journal of High Energy Physics, 2023
The entanglement entropy of a free scalar field in its ground state is dominated by an area law term. It is noteworthy, however, that the study of entanglement in scalar field theory has not advanced far beyond the ground state.
