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.

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.

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

From locality to irregularity: introducing local quenches in massive scalar field theory
Journal of High Energy Physics, 2023 In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider the dynamics of excited local states in massive scalar field theory in an arbitrary spacetime dimension and generalize the well-known two ...
