Asymptotically free scalar curvature-ghost coupling in Quantum Einstein Gravity
Astrid Eichhorn, Holger Gies, Michael M. Scherer
We consider the asymptotic-safety scenario for quantum gravity which constructs a non-perturbatively renormalisable quantum gravity theory with the help of the functional renormali…
Phase Diagram and Fixed-Point Structure of two dimensional N=1 Wess-Zumino Models
Franziska Synatschke, Holger Gies, Andreas Wipf
We study the phases and fixed-point structure of two-dimensional supersymmetric Wess-Zumino models with one supercharge. Our work is based on the functional renormalization group f…
Interplay between geometry and temperature for inclined Casimir plates
Alexej Weber, Holger Gies
We provide further evidence for the nontrivial interplay between geometry and temperature in the Casimir effect. We investigate the temperature dependence of the Casimir force betw…
Scalar heat kernel with boundary in the worldline formalism
Fiorenzo Bastianelli, Olindo Corradini, Pablo A. G. Pisani +1
The worldline formalism has in recent years emerged as a powerful tool for the computation of effective actions and heat kernels. However, implementing nontrivial boundary conditio…
Flow Equation for Supersymmetric Quantum Mechanics
Franziska Synatschke, Georg Bergner, Holger Gies +1
We study supersymmetric quantum mechanics with the functional RG formulated in terms of an exact and manifestly off-shell supersymmetric flow equation for the effective action. We…
Dynamically assisted Schwinger mechanism
Ralf Schützhold, Holger Gies, Gerald Dunne
We study electron-positron pair creation {from} the Dirac vacuum induced by a strong and slowly varying electric field (Schwinger effect) which is superimposed by a weak and rapidl…
