Gauge-invariant spectral description of the $U (1)$ Higgs model from local composite operators

David Dudal, Duive Maria van Egmond, Marcelo Santos Guimaraes +4

The spectral properties of a set of local gauge-invariant composite operators are investigated in the $U (1)$ Higgs model quantized in the 't Hooft $R_{ξ}$ gauge. These operators enab…

Eigenbranes in Jackiw-Teitelboim gravity

Andreas Blommaert, Thomas G. Mertens, Henri Verschelde

It was proven recently that JT gravity can be defined as an ensemble of L x L Hermitian matrices. We point out that the eigenvalues of the matrix correspond in JT gravity to FZZT-t…

Landau-Khalatnikov-Fradkin Transformations, Nielsen Identities, Their Equivalence and Implications for QCD

Tim De Meerleer, David Dudal, Silvio Paolo Sorella +2

The Landau-Khalatnikov-Fradkin transformations (LKFTs) represent an important tool for probing the gauge dependence of the correlation functions within the class of linear covarian…

$T T ˉ$ deformed CFT as a non-critical string

Nele Callebaut, Jorrit Kruthoff, Herman Verlinde

We present a new exact treatment of $T T ˉ$ deformed 2D CFT in terms of the worldsheet theory of a non-critical string. The transverse dimensions of the non-critical string are…

Extracting topological information from momentum space propagators

Fabrizio Canfora, David Dudal, Alex Giacomini +3

A new topological invariant quantity, sensitive to the analytic structure of both fermionic and bosonic propagators, is proposed. The gauge invariance of our construct is guarantee…

Infinitesimal Gribov copies in gauge-fixed topological Yang-Mills theories

D. Dudal, C. P. Felix, O. C. Junqueira +5

We study the Gribov problem in four-dimensional topological Yang-Mills theories following the Baulieu-Singer approach in the (anti-)self-dual Landau gauges. This is a gauge-fixed a…

Anisotropic string tensions and inversely magnetic catalyzed deconfinement from a dynamical AdS/QCD model

Hardik Bohra, David Dudal, Ali Hajilou +1

We extend previous work on dynamical AdS/QCD models by introducing an extra ingredient under the form of a background magnetic field, this to gain insight into the influence such f…

Some remarks on the spectral functions of the Abelian Higgs Model

D. Dudal, D. M. van Egmond, M. S. Guimaraes +5

We consider the unitary Abelian Higgs model and investigate its spectral functions at one-loop order. This analysis allows to disentangle what is physical and what is not at the le…

Defects in Jackiw-Teitelboim Quantum Gravity

Thomas G. Mertens, Gustavo J. Turiaci

We classify and study defects in 2d Jackiw-Teitelboim gravity. We show these are holographically described by a deformation of the Schwarzian theory where the reparametrization mod…

Towards Black Hole Evaporation in Jackiw-Teitelboim Gravity

Thomas G. Mertens

Using a definition of the bulk frame within 2d Jackiw-Teitelboim gravity, we go into the bulk from the Schwarzian boundary. Including the path integral over the Schwarzian degrees…
