Debye screening in strongly coupled N=4 supersymmetric Yang-Mills plasma

, 2007
Using the AdS/CFT correspondence, we examine the behavior of correlators of Polyakov loops and other operators in N=4 supersymmetric Yang-Mills theory at non-zero temperature.

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.

QCD String as an Effective String

, 2012
There are two cases where QCD string is described by an effective theory of long strings: the static potential and meson scattering amplitudes in the Regge regime.

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 ...

Confined Phase In The Real Time Formalism And The Fate Of The World Behind The Horizon

, 2005
In the real time formulation of finite temperature field theories, one introduces an additional set of fields (type-2 fields) associated to each field in the original theory (type-1 field). In hep-th/0106112, in the context of the AdS-CFT correspondence,

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 ...

Electric Flux Sectors and Confinement

, 2002
We study the fate of static fundamental charges in the thermodynamic limit from Monte-Carlo simulations of SU(2) with suitable boundary conditions.Comment: Presented by L.v.S. at the NATO Advanced Research Workshop "Confinement, Topology, and other Non-

Cubic order for spatial 't Hooft loop in hot QCD

, 2003
Spatial 't Hooft loops of strength k measure the qualitative change in the behaviour of electric colour flux in confined and deconfined phase of SU(N) gauge theory.

From Free Fields to AdS -- Thermal Case

, 2005
We analyze the reorganization of free field theory correlators to closed string amplitudes investigated in hep-th/0308184 hep-th/0402063 hep-th/0409233 hep-th/0504229 in the case of Euclidean thermal field theory and study how the dual bulk geometry is ...
