Functional Renormalization Group meets Computational Fluid Dynamics: RG flows in a multi-dimensional field space
Niklas Zorbach, Adrian Koenigstein, Jens Braun
Within the Functional Renormalisation Group (FRG) approach, we present a fluid-dynamical approach to solving flow equations for models living in a multi-dimensional field space. To…
Functional renormalization of QCD in dimensions: four-fermion interactions from quark-gluon dynamics
Eric Oevermann, Adrian Koenigstein, Stefan Floerchinger
Quantum Chromodynamics in two spacetime dimensions is investigated with the Functional Renormalization Group. We use a functional formulation with covariant gauge fixing and derive…
Solving the Lindblad equation with methods from computational fluid dynamics
Jan Rais, Adrian Koenigstein, Niklas Zorbach +1
Liouvillian dynamics describes the evolution of a density operator in closed quantum systems. One extension towards open quantum systems is provided by the Lindblad equation. It is…
Revisiting the spatially inhomogeneous condensates in the -dimensional chiral Gross-Neveu model via the bosonic two-point function in the infinite- limit
Adrian Koenigstein, Marc Winstel
This work shows that the known phase boundary between the phase with chiral symmetry and the phase of spatially inhomogeneous chiral symmetry breaking in the phase diagram of the $…
