Synthetic images aid the recognition of human-made art forgeries
Johann Ostmeyer, Ludovica Schaerf, Pavel Buividovich +3
Previous research has shown that Artificial Intelligence is capable of distinguishing between authentic paintings by a given artist and human-made forgeries with remarkable accurac…
Art Authentication with Vision Transformers
Ludovica Schaerf, Carina Popovici, Eric Postma
In recent years, Transformers, initially developed for language, have been successfully applied to visual tasks. Vision Transformers have been shown to push the state-of-the-art in…
Spectra of heavy quarkonia in a Bethe-Salpeter-equation approach
Thomas Hilger, Carina Popovici, Maria Gomez-Rocha +1
In a covariant Bethe-Salpeter-equation approach and with a rainbow-ladder truncated model of QCD, we investigate the use of an effective interaction with the goal of reproducing QC…
On a new approach to meson phenomenology with the Bethe-Salpeter equation
Carina Popovici, Thomas Hilger, Maria Gomez-Rocha +1
We investigate capabilities of the effective interaction in a rainbow-ladder truncated meson model of QCD within a covariant Landau-gauge Bethe-Salpeter-equation approach. Based up…
Heavy tetraquark confining potential in Coulomb gauge QCD
Carina Popovici, Christian S. Fischer
We present an analytic nonperturbative solution of the Yakubovsky equation for tetraquark states in the case of equal separations and energies, and demonstrate a direct connection…
Fermi velocity renormalization and dynamical gap generation in graphene
C. Popovici, C. S. Fischer, L. von Smekal
We study the renormalization of the Fermi velocity by the long-range Coulomb interactions between the charge carriers in the Dirac-cone approximation for the effective low-energy d…
