Aharonov-Bohm effect in curved space and cosmic strings
Yurii Sitenko, Alexei Mishchenko
A quantum theory is developed for the scattering of a nonrelativistic particle in the field of a cosmic string regarded as a combination of a magnetic and gravitational strings. Al…

Self-Adjointness and Polarization of the Fermionic Vacuum in the Background of Nontrivial Topology
Yu. A. Sitenko, D. G. Rakityansky
Singular configuration of an external static magnetic field in the form of a string polarizes vacuum in the secondly quantized theory on a plane which is orthogonal to the string a…

Nonlocality, Self-Adjointness and Theta-Vacuum in Quantum Field Theory in Spaces with Nontrivial Topology
Yu. A. Sitenko
We consider an analogue of the Aharonov-Bohm effect in quantum field theory: the fermionic vacuum attains nontrivial quantum numbers in the background of a magnetic vortex even in…
