Science Newsletter of the Faculty fo Physics
This is a new bulletin, which, as we hope, will bring fresh, updated information on scientific news, research activities, and related events in the life of our department to our staff members, undegraduate and graduate students, postdocs, collaborators and partners. We greatly hope that this Science Newsletter will help us to find new partners in research and shorten the way from fundamental research to applications and innovations, from our fundamental discoveries to their successful implementations in not too distant future.
XIV National School-Seminar "Wave phenomena in inhomogeneous media"
The conference papers from the School-Seminar «Waves-2014» will be submitted for publishing in the Memoirs of the Faculty of Physics journal.

We give a detailed analysis of two fundamental papers by E. Rutherford (1911) and N. Bohr (1913) where basics of the theory of atomic structure and spectra were developed. We show what influence these works exerted on the development of modern physics. Hide Abstract

The main notions of semiclassical scalar electrodynamics are discussed. Different approaches for quantizing scalar electrodynamics are considered. These are Couloumb gauge quantization, refined algebraic quantization and Gupta-Bleuler (or BRST-BFV) quantization. In the semiclassical theory, set of all semiclassical states are viewed as a bundle. The base of the bundle is considered as an extended phase space of the corresponding classical theory. Fibres are quantum states in external background. Semiclassical observables are expressed via differential 1-forms on the extended phase space.

In the present work we consider the quantum analogue of Riemann’s zeta-function and its alternating version. Formulas for representation of zeta-functions in the form of a functional series and values in the negative integral points are given. For classical limit are obtained known
results. We consider field theory for kinetic term with quantum alternating zeta-function and discuss mass spectrum here.
