Running coupling at finite temperature and chiral symmetry restoration in QCD
Jens Braun, Holger Gies
We analyze the running gauge coupling at finite temperature for QCD, using the functional renormalization group. The running of the coupling is calculated for all scales and temper…
Quantum energies with worldline numerics
Holger Gies, Klaus Klingmuller
We present new results for Casimir forces between rigid bodies which impose Dirichlet boundary conditions on a fluctuating scalar field. As a universal computational tool, we emplo…
Chiral phase structure of QCD with many flavors
Holger Gies, Joerg Jaeckel
We investigate QCD with a large number of massless flavors with the aid of renormalization group flow equations. We determine the critical number of flavors separating the phases w…
Geometry of spin-field coupling on the worldline
Holger Gies, Jens Hammerling
We derive a geometric representation of couplings between spin degrees of freedom and gauge fields within the worldline approach to quantum field theory. We combine the string-insp…
Pair production in inhomogeneous fields
Holger Gies, Klaus Klingmuller
We employ the recently developed worldline numerics, which combines string-inspired field theory methods with Monte-Carlo techniques, to develop an algorithm for the computation of…
