External Fields as a Probe for Fundamental Physics
Holger Gies
Quantum vacuum experiments are becoming a flexible tool for investigating fundamental physics. They are particularly powerful for searching for new light but weakly interacting deg…
Hidden in the Light: Magnetically Induced Afterglow from Trapped Chameleon Fields
Holger Gies, David F. Mota, Douglas J. Shaw
We propose an afterglow phenomenon as a unique trace of chameleon fields in optical experiments. The vacuum interaction of a laser pulse with a magnetic field can lead to a product…
Worldline Approach to Chiral Fermions
Kurt Langfeld, Gerald Dunne, Holger Gies +1
We propose to apply ``worldline numerics'' to a numerical calculation of quark determinants. The Gross-Neveu model with a U(1) chiral symmetry is considered as a first test. The wo…
Renormalisation Flow and Universality for Ultracold Fermionic Atoms
S. Diehl, H. Gies, J. M. Pawlowski +1
A functional renormalisation group study for the BEC-BCS crossover for ultracold gases of fermionic atoms is presented. We discuss the fixed point which is at the origin of univers…
