On effects of non-Euclidean geometry in quantum theory
Yu. A. Sitenko, N. D. Vlasii
Theory of scattering of a quantum-mechanical particle on a cosmic string is developed. S-matrix and scattering amplitude are determined as functions of the flux and the tension of…
Effects of singular external fields and boundary condition on the vacuum of massless fermions in QFT
Yu. A. Sitenko
Effects of the configuration of an external static magnetic field in the form of a singular vortex on the vacuum of a quantized massless spinor field are studied. The most general…
Polarization of the Massless Fermionic Vacuum in the Background of a Singular Magnetic Vortex in 2+1-Dimensional Space-Time
Yu. A. Sitenko
Effects of the configuration of an external static magnetic field in the form of a singular vortex on the vacuum of a quantized massless spinor field are determined. The most gener…
Self-Adjointness of the Dirac Hamiltonian and Vacuum Quantum Numbers Induced by a Singular External Field
Yu. A. Sitenko
Effects of fermion-vacuum polarization by a singular configuration of an external static vector field are considered in (2 + 1)-dimensional spacetime. Expressions for the induced v…
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…
