Discrete heat kernel, UV modified Green's function, and higher derivative theories

Nahomi Kan, Masashi Kuniyasu, Kiyoshi Shiraishi +1

We perform the UV deformation of the Green's function in free scalar field theory using a discrete heat kernel method. It is found that the simplest UV deformation based on the dis…

Vacuum expectation values in non-trivial background space from three types of UV improved Green's functions

Nahomi Kan, Masashi Kuniyasu, Kiyoshi Shiraishi +1

We evaluate the quantum expectation values in non-simply connected spaces by using UV improved Green's functions proposed by Padmanabhan, Abel, and Siegel. It is found that the res…
