Why the Quark-Gluon Plasma isn't a Plasma [PDF]

, 2001
An alternate picture of the deconfined phase of gauge theories is described. Instead of a plasma, the theory is viewed as a condensate of Polyakov lines.

String tensions in deformed Yang-Mills theory

Journal of High Energy Physics, 2018
We study k-strings in deformed Yang-Mills (dYM) with SU(N) gauge group in the semiclassically calculable regime on ℝ3×S1 $$ {\mathbb{R}}^3\times {\mathbb{S}}^1 $$.

The planar limit of N $$ \mathcal{N} $$ = 2 superconformal field theories

Journal of High Energy Physics, 2020
We obtain the perturbative expansion of the free energy on S 4 for four dimensional Lagrangian N $$ \mathcal{N} $$ = 2 superconformal field theories, to all orders in the ’t Hooft coupling, in the planar limit.

Precision Lattice Calculation of SU(2) 't Hooft loops [PDF]

, 2005
The [dual] string tension of a spatial 't Hooft loop in the deconfined phase of Yang-Mills theory can be formulated as the tension of an interface separating different Z_N deconfined vacua.

Line operators in the Standard Model

Journal of High Energy Physics, 2017
There is an ambiguity in the gauge group of the Standard Model. The group is G = SU(3) × SU(2) × U(1)/Γ, where Γ is a subgroup of Z 6 which cannot be determined by current experiments.

Semi-Abelian gauge theories, non-invertible symmetries, and string tensions beyond N-ality

Journal of High Energy Physics, 2021
We study a 3d lattice gauge theory with gauge group U(1) N−1 ⋊ S N , which is obtained by gauging the S N global symmetry of a pure U(1) N−1 gauge theory, and we call it the semi-Abelian gauge theory.

A path integral formulation for particle detectors: the Unruh-DeWitt model as a line defect

Journal of High Energy Physics, 2021
Particle detectors are an ubiquitous tool for probing quantum fields in the context of relativistic quantum information (RQI). We formulate the Unruh-DeWitt (UDW) particle detector model in terms of the path integral formalism. The formulation is able to

Monopole characteristics in various Abelian gauges [PDF]

, 1999
Renormalization group (RG) smoothing is employed on the lattice to investigate and to compare the monopole structure of the SU(2) vacuum as seen in different gauges (maximally Abelian (MAG), Polyakov loop (PG) and Laplacian gauge (LG)).

Ironing out the crease

Journal of High Energy Physics, 2022
The crease is a surface operator folded by a finite angle along an infinite line. Several realisations of it in the 6d N $$ \mathcal{N} $$ = (2, 0) theory are studied here. It plays a role similar to the generalised quark-antiquark potential, or the cusp

The planar limit of N $$ \mathcal{N} $$ = 2 superconformal quiver theories

Journal of High Energy Physics, 2020
We compute the planar limit of both the free energy and the expectation value of the 1/2 BPS wilson loop for four dimensional N $$ \mathcal{N} $$ = 2 superconformal quiver theories, with a product of SU(N)s as gauge group and hi-fundamental matter ...
