Entanglement of heavy quark impurities and generalized gravitational entropy

Journal of High Energy Physics, 2018
We calculate the contribution from non-conformal heavy quark sources to the entanglement entropy (EE) of a spherical region in N=4 $$ \mathcal{N}=4 $$ SUSY Yang-Mills theory.

Subleading Regge limit from a soft anomalous dimension

Journal of High Energy Physics, 2018
Wilson lines capture important features of scattering amplitudes, for example soft effects relevant for infrared divergences, and the Regge limit. Beyond the leading power approximation, corrections to the eikonal picture have to be taken into account ...

Wall-crossing and operator ordering for ’t Hooft operators in N $$ \mathcal{N} $$ = 2 gauge theories

Journal of High Energy Physics, 2019
We study half-BPS ’t Hooft line operators in 4d N $$ \mathcal{N} $$ = 2 U(N ) gauge theories on S 1 × ℝ3 with an Ω-deformation. The recently proposed brane construction of ’t Hooft operators shows that non-perturbative contributions to their correlator ...

Generalized symmetry in dynamical gravity

Journal of High Energy Physics
We explore generalized symmetry in the context of nonlinear dynamical gravity. Our basic strategy is to transcribe known results from Yang-Mills theory directly to gravity via the tetrad formalism, which recasts general relativity as a gauge theory of ...

The influence of Wilson lines on heavy quark anti-quark potential and mass

Journal of High Energy Physics
The holographic heavy quark potential is investigated via holographic Wilson loops in the AdS soliton with gauge potential. We analyze two types of holographic Wilson loops. In the first type, holographic heavy quark potential shows the area law behavior.

Two-loop four-point amplitudes on the Coulomb branch of N $$ \mathcal{N} $$ = 4 super Yang-Mills

Journal of High Energy Physics
We explore scattering amplitudes on the Coulomb branch of maximally supersymmetric Yang-Mills theory. We introduce a particular pattern of scalar vacuum expectation values that allow us to define amplitudes with a different mass pattern compared to what ...

A new method for calculating the soft anomalous dimension matrix for massive particle scattering

Journal of High Energy Physics
The general structure of infrared divergences in the scattering of massive particles is captured by the soft anomalous dimension matrix. The latter can be computed from a correlation function of multiple Wilson lines. The state-of-the-art two-loop result

A two-loop four-point form factor at function level

Journal of High Energy Physics
Recently, the maximally-helicity-violating four-point form factor for the chiral stress-energy tensor in planar N $$ \mathcal{N} $$ = 4 super Yang-Mills was computed to three loops at the level of the symbol associated with multiple polylogarithms.

Matrix bootstrap approximation without positivity constraint

Journal of High Energy Physics
We propose a bootstrap approximation method for the Hermitian one-matrix model that does not rely on positivity constraints. The theoretical foundation of this method is that the one-matrix model admits an eigenvalue distribution ρ(λ), and that the ...
