Exact Pair Production Rate for a Smooth Potential Step
A. Chervyakov, H. Kleinert
We derive the exact rate of pair production of oppositely charged scalar particles by a smooth potential proportional to tanh kz in three dimensions. As a check we recover from thi…

Perturbation Theory for Path Integrals of Stiff Polymers
H. Kleinert, A. Chervyakov
The wormlike chain model of stiff polymers is a nonlinear -model in one spacetime dimension in which the ends are fluctuating freely. This causes important differences with resp…

Perturbatively Defined Effective Classical Potential in Curved Space
H. Kleinert, A. Chervyakov
The partition function of a quantum statistical system in flat space can always be written as an integral over a classical Boltzmann factor $\exp[ -βV^{\rm eff cl({\bf x}_0)]$, whe…
