Zeta-regularized vacuum expectation values from quantum computing simulations
Karl Jansen, Tobias Hartung
The zeta-regularization allows to establish a connection between Feynman's path integral and Fourier integral operator zeta-functions. This fact can be utilized to perform the regu…

Integrating Gauge Fields in the -formulation of Feynman's path integral
Tobias Hartung, Karl Jansen
In recent work by the authors, a connection between Feynman's path integral and Fourier integral operator -functions has been established as a means of regularizing the vacuum e…
