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.

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

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.

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

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

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.
