Quark-antiquark potential in defect conformal field theory

Journal of High Energy Physics, 2017
We consider antiparallel Wilson lines in N $$ \mathcal{N} $$ = 4 super Yang-Mills in the presence of a codimension-1 defect. We compute the Wilson lines’ expectation value both at weak coupling, in the gauge theory, and at strong coupling, by finding the

String corrections to circular Wilson loop and anomalies

Journal of High Energy Physics, 2018
We study string quantum corrections to the ratio of latitude and circular Wilson loops in N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory at strong coupling. Conformal gauge for the corresponding minimal surface in AdS5 × S 5 is singular and we show that

Study of gapped phases of 4d gauge theories using temporal gauging of the ℤ N 1-form symmetry

Journal of High Energy Physics, 2023
To study gapped phases of 4d gauge theories, we introduce the temporal gauging of ℤ N 1-form symmetry in 4d quantum field theories (QFTs), thereby defining effective 3d QFTs with ℤ ~ $$ \overset{\sim }{\mathbb{Z}} $$ N × ℤ N 1-form symmetry. In this way,

Large-$N_c$ gauge theory and chiral random matrix theory

, 2013
We discuss how the $1/N_c$ expansion and the chiral random matrix theory ($\chi$RMT) can be used in the study of large-$N_c$ gauge theories. We first clarify the parameter region in which each of these two approaches is valid: while the fermion mass $m ...

Free Energy and Phase Transition of the Matrix Model on a Plane-Wave [PDF]

, 2004
It has recently been observed that the weakly coupled plane wave matrix model has a density of states which grows exponentially at high energy. This implies that the model has a phase transition. The transition appears to be of first order.

Computing Wilson lines with dielectric branes

, 2006
Wilson lines in N=4SYM can be computed in terms of branes carrying electric flux, i.e. F-strings dissolved in their worldvolumes. It is then natural to think that those configurations are the effective description of strings expanding due to dielectric ...

Topological aspects of QCD [PDF]

, 1995
We review recent results from lattice on topological aspects of QCD: most of the results refer to monopoles and to instantons. We discuss in detail the evidence for condensation of monopoles in the vacuum and confinement of colour by dual ...

Circular Wilson loop in N $$ \mathcal{N} $$ = 2* super Yang-Mills theory at two loops and localization

Journal of High Energy Physics, 2021
We present a two-loop calculation of the supersymmetric circular Wilson loop in the N $$ \mathcal{N} $$ = 2* super Yang-Mills theory on the four-sphere. We develop an efficient framework for computing contributing Feynman graphs that relies on using the ...

Lattice instanton action from 3D SU(2) Georgi-Glashow model

, 2001
3D Georgi-Glashow model is studied on the lattice in the London limit in an infrared but an intermediate region before the screening appears. Abelian and instanton dominances are observed after abelian projections in a unitary gauge and roughly in the ...
