Perturbative Yang-Mills theory without Faddeev-Popov ghost fields
Helmuth Huffel, Danijel Markovic
A modifed Faddeev-Popov path integral density for the quantization of Yang-Mills theory in the Feynman gauge is discussed, where contributions of the Faddeev-Popov ghost fields are…
Ergostatting and Thermostatting at a Fixed Point
Helmuth Huffel, Sasa Ilijic
We propose a novel type of ergostats and thermostats for molecular dynamics simulations. A general class of active particle swarm models is considered, where any specific total ene…
Swarms with canonical active Brownian motion
Alexander Gluck, Helmuth Huffel, Sasa Ilijic
We present a swarm model of Brownian particles with harmonic interactions, where the individuals undergo canonical active Brownian motion, i.e. each Brownian particle can convert i…
The Active Universe
Alexander Gluck, Helmuth Huffel, Sasa Ilijic +1
Active motion is a concept in complex systems theory and was successfully applied to various problems in nonlinear dynamics. Explicit studies for gravitational potentials were miss…
Nonlinear Phenomena in Canonical Stochastic Quantization
Helmuth Huffel
Stochastic quantization provides a connection between quantum field theory and statistical mechanics, with applications especially in gauge field theories. Euclidean quantum field…
Quantizing Yang-Mills Theory on a 2-Point Space
H. Huffel
We perform the Batalin-Vilkovisky quantization of Yang-Mills theory on a 2-point space, discussing the formulation of Connes-Lott as well as Connes' real spectral triple approach.…
Quantizing Yang-Mills Theory: From Parisi-Wu Stochastic Quantization to a Global Path Integral
Helmuth Huffel, Gerald Kelnhofer
Based on a generalization of the stochastic quantization scheme we recently proposed a generalized, globally defined Faddeev-Popov path integral density for the quantization of Yan…
Global Path Integral Quantization of Yang-Mills Theory
Helmuth Huffel, Gerald Kelnhofer
Based on a generalization of the stochastic quantization scheme recently a modified Faddeev-Popov path integral density for the quantization of Yang-Mills theory was derived, the m…
Generalized Stochastic Quantization of Yang-Mills Theory
Helmuth Huffel, Gerald Kelnhofer
We perform the stochastic quantization of Yang-Mills theory in configuration space and derive the Faddeev-Popov path integral density. Based on a generalization of the stochastic g…
Nonperturbative Stochastic Quantization of the Helix Model
Helmuth Huffel, Gerald Kelnhofer
The helix model describes the minimal coupling of an abelian gauge field with three bosonic matter fields in 0+1 dimensions; it is a model without a global Gribov obstruction. We p…
Generalized Stochastic Gauge Fixing
Helmuth Huffel, Gerald Kelnhofer
We propose a generalization of the stochastic gauge fixing procedure for the stochastic quantization of gauge theories where not only the drift term of the stochastic process is ch…
Transition Amplitudes within the Stochastic Quantization Scheme
H. Hüffel, H. Nakazato
Quantum mechanical transition amplitudes are calculated within the stochastic quantization scheme for the free nonrelativistic particle, the harmonic oscillator and the nonrelativi…
