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 $$ {\mathbb{R}}^3\times {\mathbb{S}}^1 $$.

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

Aspects of holographic string theory [PDF]
, 2009 In this thesis we study several aspects of gauge/gravity dualities. We start by analyzing the structure of the UV divergences of the Wilson loop for a general gauge/gravity duality.

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

Computation of the quantum effects due to a four-dimensional pseudo-particle [PDF]
, 1976 A detailed quantitative calculation is carried out of the tunneling process described by the Belavin-Polyakov-Schwarz-Tyupkin field configuration. A certain chiral symmetry is violated as a consequence of the Adler-Bell-Jackiw anomaly.

, 2009 Nous avons investigué, via les simulations de Monte Carlo, les propriétés non-perturbatives du modèle de Higgs abélien en 2+1 dimensions sans et avec le terme de Chern-Simons dans la phase de symétrie brisée, en termes de ses excitations topologiques ...

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.

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 ...

Interpolating Wilson loops and enriched RG flows
Journal of High Energy Physics, 2023 We study new 1/24 BPS circular Wilson loops in ABJ(M) theory, which are defined in terms of several parameters that continuously interpolate between previously known 1/6 BPS loops (both bosonic and fermionic) and 1/2 BPS fermionic loops.

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.
