Spectra of light and heavy mesons with in a relativistic Bethe-Salpeter approach
Stephan Hagel, Christian S. Fischer, Markus Q. Huber +1
We extend the range of application of the relativistic Dyson-Schwinger/Bethe-Salpeter approach from previously discussed mesons with total angular momentum to the ones wi…
Apparent convergence in functional glueball calculations
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
We scrutinize the determination of glueball masses in pure Yang-Mills theory from functional equations, i.e. Dyson-Schwinger and Bethe-Salpeter equations. We survey the state-of-th…
Glueballs from Dyson-Schwinger and Bethe-Salpeter equations
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
The quenched spectrum of glueballs with positive charge parity is calculated from two-body bound state equations. As input, a self-contained solution for the primitively divergent…
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…
Effects of electron-electron interactions in suspended graphene
C. Popovici, C. S. Fischer, L. von Smekal
We investigate the problem of dynamical gap generation in suspended graphene by long-range Coulomb interactions at strong coupling with Dyson-Schwinger equations. Including renorma…
