The influence of elementary excitations and conformations to physical properties of the new materials based on strongly correlated low-dimensional systems

The subject of the study are strongly correlated systems appearing in the condensed matter physics and biophysics. We are dealing with new families of HTcSC materials, frustrated magnetic systems, magnetic semiconductors, conducting polymers, biological macromolecules etc. Common for these materials are the complex structure, low dimensionality, layers, rather specific magnetic, conducting, transport and other properties. This research should contribute to a more complete understanding of magnetic properties of actual HTcSC materials as well as obtaining a more clear picture of the influence of spin quantum fluctuations and various types of geometry onto magnetic properties of low-dimensional antiferromagnetic systems. In the case of frustrated magnetic systems, one should clarify the importance of interlayer exchange interaction for the critical properties. The elementary excitations of ferromagnetic semiconductor thin films and multilayers will be analyzed in order to study their thermodynamic properties. The research in the field of soft matter pertains the physical aspects of dynamics of some of essential functional molecules of living cell, such as microtubules, actin filaments, motor proteins, DNA, RNA and RNA polymerase. Their functional conformations will be examined taking into account their inherent nonlinear character. Ionic current flows along microtubules are analyzed as well as electron currents along DNA chains and other quasi 1d materials.
