Capacity of entanglement in local operators
Journal of High Energy Physics, 2021 We study the time evolution of the excess value of capacity of entanglement between a locally excited state and ground state in free, massless fermionic theory and free Yang-Mills theory in four spacetime dimensions.

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.

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.

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.

2-Group global symmetries and anomalies in six-dimensional quantum field theories [PDF]
Journal of High Energy Physics, 2020 We examine six-dimensional quantum field theories through the lens of higher-form global symmetries. Every Yang-Mills gauge theory in six dimensions, with field strength f(2), naturally gives rise to a continuous 1-form global symmetry associated with ...

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

Oscillons in higher-derivative effective field theories [PDF]
Physical Review D, 2018 We investigate the existence and behavior of oscillons in theories in which higher derivative terms are present in the Lagrangian, such as galileons.

Yang-Mills, Gravity, and String Symmetries [PDF]
, 1996 In this work we use constructs from the dual space of the semi-direct product of the Virasoro algebra and the affine Lie algebra of a circle to write a theory of gravitation which is a natural analogue of Yang-Mills theory. The theory provides a relation

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 ...
