Asymptotic safety: a simple example
Jens Braun, Holger Gies, Daniel D. Scherer
We use the Gross-Neveu model in 2<d<4 as a simple fermionic example for Weinberg's asymptotic safety scenario: despite being perturbatively nonrenormalizable, the model defines an…
High-Intensity Probes of Axion-Like Particles
Babette Döbrich, Holger Gies
With continuously increasing intensities, modern laser systems can become a valuable tool for the search for axions and axion-like particles. As conventional setups of axion search…
Functional renormalization for the BCS-BEC crossover
Michael M. Scherer, Stefan Floerchinger, Holger Gies
We review the functional renormalization group (RG) approach to the BCS-BEC crossover for an ultracold gas of fermionic atoms. Formulated in terms of a scale-dependent effective ac…
Gluon condensation and scaling exponents for the propagators in Yang-Mills theory
Astrid Eichhorn, Holger Gies, Jan M. Pawlowski
We investigate the infrared (strong-coupling) regime of SU(N)-Yang-Mills theory on a self-dual background. We present an evaluation of the full effective potential for the field st…
