Exploring Entanglement Entropy for a Particle on a Torus with constant Metric and constant -Gauge Field
Helmuth Huffel, Gerald Kelnhofer
In this paper, we focus on the entanglement entropy associated with a particle confined to a torus with constant metric and -terms related to a constant external -gauge fi…
Field Space Entanglement Entropy, Zero Modes and Lifshitz Models
Helmuth Huffel, Gerald Kelnhofer
The field space entanglement entropy of a quantum field theory is obtained by integrating out a subset of its fields. We study an interacting quantum field theory consisting of mas…
Nonlinear Brownian Motion and Higgs Mechanism
Alexander Gluck, Helmuth Huffel
An extension of the stochastic quantization scheme is proposed by adding nonlinear terms to the field equations. Our modification is motivated by the recently established theory of…
QED Revisited: Proving Equivalence Between Path Integral and Stochastic Quantization
Helmuth Huffel, Gerald Kelnhofer
We perform the stochastic quantization of scalar QED based on a generalization of the stochastic gauge fixing scheme and its geometric interpretation. It is shown that the stochast…
BV-Quantization of a Noncommutative Yang-Mills Theory Toy Model
H. Huffel
We review the Batalin-Vilkovisky quantization procedure for Yang--Mills theory on a 2-point space.
Global Aspects of Quantizing Yang-Mills Theory
Helmuth Huffel, Gerald Kelnhofer
We review recent results on the derivation of a global path integral density for Yang-Mills theory. Based on a generalization of the stochastic quantization scheme and its geometri…
