Scientific Programme:
The main goals are to predict and analyze properties of atomic nuclei beyond the stability valley and investigate structure peculiarities of superheavy and exotic nuclei; to study dynamics of nuclear collisions at low and intermediate energies accompanied by production of stable as well as radioactive nuclides; to investigate fundamental properties of various few-body systems and develop rigorous and effective mathematical methods of calculations of their properties; to explore the dynamics of particle-nucleus and nucleus-nucleus collisions at relativistic energies and nuclear matter properties and its phase transitions at extreme values of temperature and density.

Expected main results in 2015:

Studies of the effects of phonon-phonon coupling on distributions of E0-, E1- and E2- transition strengths in the neutron-rich N=82 isotones in a wide region of excitation enegies.

Analysis of anomalous deformation splitting of the E1(T=0) toroidal mode

Development of the microscopic proton-neutron symplectic model of collective motions.

Creation of a database on theoretical beta-decay rates for fission and fragmentation products.

Elucidation of the role of the screening effect in calculation of the phase space factors in single and double beta decays.
Development of the method to describe phase transitions in the alternating parity bands of even-even nuclei occurring with the increase of the angular momentum.

Investigation of the formation cross section of neutron-deficient nuclides in incomplete fusion and quasifission reactions as a function of the isospin of colliding nuclei.

Study of the mechanism and dynamics of transformation of the mononucleus to the dinuclear system along the fission process of a heavy nucleus.

Dynamic adiabatic representation of inelastic processes in atomic collisions.
Systematic studies of multi-photon processes in interaction of probe photons and charge leptons and quarks with intensive ultra-short electromagnetic fields both induced and external (generated by lasers of high power).

Analysis of asimuthal correlations of hadrons produced in ultrarelativistic heavy-ion collisions in the case of asymmetric Cu+Au combinations in terms of parton-hadron string dynamics model.

Realistic calculations of the spin dependent spectral functions of polarized few-body systems with taking into account the final state interaction and calculations of Collin's and Siver's asymmetries of polarized ³He to extract transverse parton distributions of neutrons.

Investigation of the masses and widths of dibaryons in nucleon-nucleon scattering for J=2 within Bethe-Salpeter approach.

Study of the thermodynamic properties of the free neutral scalar field in the framework of the method of the path integral quantization both for the finite sizes of the lattice and in the continuum limit.
