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.

BPS property and its breaking in 1+1 dimensions [PDF]
Physical Review D, 2018 We show that the BPS property is a generic feature of field theories in (1+1) dimensions, which does not put any restriction on the action. Here, by BPS solutions we understand static solutions which i) obey a lower-order Bogomolny-type equation in ...

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Universal bounds on operator dimensions from the average null energy condition [PDF]
Journal of High Energy Physics, 2017 We show that the average null energy condition implies novel lower bounds on the scaling dimensions of highly-chiral primary operators in four-dimensional conformal field theories.

Entanglement dynamics after a quench in Ising field theory: a branch point twist field approach
Journal of High Energy Physics, 2019 We extend the branch point twist field approach for the calculation of entanglement entropies to time-dependent problems in 1+1-dimensional massive quantum field theories.

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.

Journal of High Energy Physics, 2019 In this paper we study the increment of the entanglement entropy and of the (replica) logarithmic negativity in a zero-density excited state of a free massive bosonic theory, compared to the ground state.

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

T-duality and U-duality in toroidally-compactified strings [PDF]
, 1997 We address the issue of T-duality and U-duality symmetries in the toroidally-compactified type IIA string. It is customary to take as a starting point the dimensionally-reduced maximal supergravity theories, with certain field strengths dualised such ...
