Statistical Aspects of Neveu and Schwarz Dual Model
M. I. Gorenstein, V. P. Shelest, Yu. A. Sitenko +1
Statistical method is applied to Neveu and Schwartz model for obtaining the average characteristics of the heavy resonances: spin distribution, decay widths etc. The properties of…
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…
Scattering in the pair of Hilbert spaces
Egor Bugrij, Alexei Mishchenko, Yurii Sitenko
The problem of the scattering of a charged test particle in the gravitational background of axially symmetrical wormhole in the presence of the Aharonov-Bohm type magnetic field is…
