Wilson loops effective theory and gauge-gravity duality
… efectiva para el dual holográfico de líneas de Wilson en teorías de campos no conformes y fuertemente acopladas y algunas aplicaciones del mecanismo obtenido. Encontramos una acción efectiva para una cuerda dual a la línea de Wilson usando el mecanismo de renormalización de Wilson donde …

Soft diffractive high energy scattering and form factors in nonperturbative QCD
… by expectation values of light-like Wegner-Wilson loops and lines, which then are then evaluated in the model of the stochastic vacuum. We describe mesons in a simple quark-antiquark picture, for baryons we assume a quark-diquark structure, as hadronic wave functions we apply a …

Hochenergiestreuung im Nichtperturbativen Vakuum der Quantenchromodynamik
… Nachtmanns f'ur die Streuung zweier Wegner-Wilson-Loops. Wir argumentieren, da's die G'ultigkeit der Formel hin zu gro'sen aber endlichen Werten von {s} erweitert werden kann dadurch, da's die urspr'unglichen nahezu lichtartigen Loops n-i-c-h-t ersetzt werden durch ihre exakt lichtartigen …

Band topology beyond symmetry eigenvalues with applications to electronic and phononic systems
… methods, homotopy theory, cohomology theory and Wilson loops. These schemes are all applied to the same system, facilitating a systematic comparison between them. We then use the interplay between these classification schemes to describe and classify novel magnetic fragile and nodal phases in 2D …

Two topics in non-perturbative lattice field theories : the U(1) quantum link model and perfect actions for scalar theories
… flux. It is shown how improved estimators for Wilson loop expectation values can be defined. This is important because the Wilson loops are traditionally used to identify confining and Coulomb phases in gauge theories. Our study indicates that the spin-1/2 U(1) quantum link model is strongly …

Inverse methods in quantum many-body physics
… phases of matter, quantum spin liquids with Wilson loops and topological superconductors with Majorana zero modes (MZMs). These phases have exotic properties, such as long-ranged entanglement and anyonic quasiparticles, that make them interesting to study and potentially useful in emerging …
