Vacuum Energy Induced by an External Magnetic Field in a Curved Space
Yu. A. Sitenko, D. G. Rakityansky
The asymptotic expansion of the product of an operator raised to an arbitrary power and an exponential function of this operator is obtained. With the aid of this expansion, the de…

Induced Angular Momentum in (2+1)-Dimensional Spinor Electrodynamics in Curved Space
Yu. A. Sitenko, D. G. Rakityansky
Effects due to fermion-vacuum polarization by an external static magnetic field are considered in a two-dimensional noncompact curved space with a nontrivial topology. An expressio…

Quantum Numbers of the Theta Vacuum in (2+1)-Dimensional Spinor Electrodynamics: Charge and Magnetic Flux
Yu. A. Sitenko, D. G. Rakityansky
A singular configuration of an external static vector field in the form of a magnetic string polarizes the vacuum of a second-quantized theory on the plane orthogonal to the string…
