Functional Renormalization Group flows as diffusive Hamilton-Jacobi-type equations
Adrian Koenigstein, Martin J. Steil, Stefan Floerchinger
In order to find reliable and efficient numerical approximation schemes, we suggest to identify the Functional Renormalization Group flow equations of one-particle irreducible two-…
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 $…
Reanalysis of critical exponents for the O(N) model via a hydrodynamic approach to the Functional Renormalization Group
Fabrizio Murgana, Adrian Koenigstein, Dirk H. Rischke
We compute the critical exponents of the O(N) model within the Functional Renormalization Group (FRG) approach. We use recent advances which are based on the observation that the F…
Fermions in worldline holography
Dennis D. Dietrich, Adrian Koenigstein
We analyse the worldline holographic framework for fermions. Worldline holography is based on the observation that in the worldline approach to quantum field theory, sources of a q…
Schwinger's proper time and worldline holographic renormalisation
Dennis D. Dietrich, Adrian Koenigstein
Worldline holography states that within the framework of the worldline approach to quantum field theory, sources of a quantum field theory over Mink naturally form a field theo…
Gauge Theory by canonical Transformations
Adrian Koenigstein, Johannes Kirsch, Horst Stoecker +3
Electromagnetism, the strong and the weak interaction are commonly formulated as gauge theories in a Lagrangian description. In this paper we present an alternative formal derivati…
Classical and quantum theory of the massive spin-two field
Adrian Koenigstein, Francesco Giacosa, Dirk H. Rischke
In this paper, we review classical and quantum field theory of massive non-interacting spin-two fields. We derive the equations of motion and Fierz-Pauli constraints via three diff…
