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.

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

One-loop CHY-integrand of bi-adjoint scalar theory
Journal of High Energy Physics, 2020 In this paper, the one-loop CHY-integrands of bi-adjoint scalar theory has been reinvestigated. Differing from previous constructions, we have explicitly removed contributions from tadpole and massless bubbles when taking the forward limit of ...

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 ...

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.

Modular energy inequalities from relative entropy
Journal of High Energy Physics, 2018 We obtain new constraints for the modular energy of general states by using the monotonicity property of relative entropy. In some cases, modular energy can be related to the energy density of states and these constraints lead to interesting relations ...

Compactifying 5d superconformal field theories to 3d
Journal of High Energy Physics, 2021 Building on recent progress in the study of compactifications of 6d (1, 0) superconformal field theories (SCFTs) on Riemann surfaces to 4d N $$ \mathcal{N} $$ = 1 theories, we initiate a systematic study of compactifications of 5d N $$ \mathcal{N} $$ = 1

An inverse mass expansion for the mutual information in free scalar QFT at finite temperature
Journal of High Energy Physics, 2020 We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish at infinite temperature, but it rather reaches a specific finite value ...

Light scalars on cosmological backgrounds
Journal of High Energy Physics, 2018 We study the behaviour of a light quartically self-interacting scalar field ϕ on curved backgrounds that may be described with the cosmological equation state parameter w.
