Laboratories IKBFU

Laboratory "Analytical and numerical modeling of nonlinear processes"

General information

Established in 2102. Staff - 8 people. Two professors.

Laboratory develops mathematical methods as well as computer and super-computer programs for research calculations.

Currently the laboratory team participates

a) project #1127: "Physical mechanisms of the upper atmosphere and ionosphere reaction to the processes in the lower atmosphere and to the surface of the Earth", funded by the Ministry of Education and Science of the Russian Federation. Financing period 2014-2016.

b) RFFR project RFBR 15-05-01665 ionospheric irregularities triggered by meteorological processes

c) studying and modeling processes in the solar plasma in collaboration with the Joint Institute for Nuclear Research, Moscow University.

d) research on computer modeling of X-rays propagation in the X-ray microscope jointly with the Gdańsk University of Technology (Poland) Research papers have not been financed yet.

e) In collaboration with the Institute of Atmospheric Physics, Russian Academy of Sciences (Moscow) and St. Petersburg State University the laboratory conducts a study on modeling and the research of wave propagation in the Earth's atmosphere as well as the effects of these waves on the parameters of the medium.

f) Together with the Gdańsk University of Technology (Poland) the laboratory carries out work on the development of new mathematical methods and computer programs for the quantum multi-particle systems simulation with a view to solving the problems related to nanotechnologies. The research has not been financed yet. New methods and test software have already been developed.

Equipment

The studies used supercomputer in I.Kant BFUand the most powerful one in Europe, the supercomputer "Lomonosov" in M.Lomonosov MSU,which features products developed by the laboratory
