popup.description1
Research is aimed at developing methods of statistical physics to describe states of multiparticle quantum systems with broken symmetries. Methods of quantum field theory will be used to study conformally invariant models of tensor fields in curved spaces and spontaneous generation of gravity.
popup.description2
In the framework of non-relativistic quantum Fermi-liquid theory there were obtained refined analytic expressions for temperatures of the phase transitions of space-homogeneous neutron matter of supranuclear densities from normal to superfluid states with anisotropic spin-triplet p-wave pairing in the stationary and homogeneous extremely strong magnetic field observed in the liquid outer core of magnetars (strongly magnetized neutron stars). Study of neutron stars, in which hadronic matter is under extreme conditions unreachable in a laboratory, is of considerable interest due to the possibility to test predictions of the Standard model and to seek for the signals of new physics. There was found the Lax representation for dynamical equations of the relativistic null-string in the space-times of constant-curvature. There was proposed novel twistor formulation of (null-)strings in the anti-de Sitter space-time. Obtained results and their generalizations can be applied to elaboration of quantum gravity based on the string theory with the use holographic principle.
