A History of Feynman's Sum over Histories in Quantum Mechanics
Akira Inomata, Georg Junker
A history of Feynman's sum over histories is presented in brief. A focus is placed on the progress of path-integration techniques for exactly path-integrable problems in quantum me…
Quantum and classical stochastic dynamics: Exactly solvable models by supersymmetric methods
Georg Junker
A supersymmetric method for the construction of so-called conditionally exactly solvable quantum systems is reviewed and extended to classical stochastic dynamical systems characte…
Coherent-state path-integral approach for constrained fermion systems
Georg Junker, John R. Klauder
The coherent-state path-integral representation for the propagator of fermionic systems subjected to first-class constraints is constructed. As in the bosonic case the importance o…
Path-Integral Aspects of Supersymmetric Quantum Mechanics
Georg Junker
In this talk we briefly review the concept of supersymmetric quantum mechanics using a model introduced by Witten. A quasi-classical path-integral evaluation for this model is perf…
Explicit thermostatics of certain classical one-dimensional lattice models by harmonic analysis
Georg Junker
A certain class of one-dimensional classical lattice models is considered. Using the method of abstract harmonic analysis explicit thermostatic properties of such models are derive…
