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 ...

Spatial 't Hooft loop to cubic order in hot QCD [PDF]

, 2002
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.

Roberge-Weiss transition and ’t Hooft loops [PDF]

, 2013
Roberge and Weiss showed that for SU(N) gauge theories, phase transitions occur in the presence of an imaginary quark chemical potential. We show that at asymptotically high temperature, where the phase transition is of first order, that even with ...

Wilson loops and defect RG flows in ABJM

Journal of High Energy Physics, 2023
We continue our study of renormalization group (RG) flows on Wilson loop defects in ABJM theory, which we have initiated in arXiv:2211.16501 . We generalize that analysis by including non-supersymmetric fixed points and RG trajectories.

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 ...

Comments on higher rank Wilson loops in N$$ \mathcal{N} $$ = 2∗ [PDF]

, 2017
A bstractFor N$$ \mathcal{N} $$ = 2∗ theory with U(N ) gauge group we evaluate expectation values of Wilson loops in representations described by a rectangular Young tableau with n rows and k columns.

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

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 ...

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,
