Dynamics of MBN systems
The next direction of the MBN research at FIAS is aimed at achieving a better understanding of dynamics of MBN systems. There are many interesting dynamical phenomena involving MBN systems, which are of interest to the MBN group at FIAS. These include nanoscale phase transitions in MBN systems, charge instabilities, particle channeling and transport phenomena, dynamics and transformations of the systems, fusion, fission, dissociation and fragmentation processes induced by collisions, temperature variation and exposure to environment or external electric, magnetic, laser fields.
On the current level of technological and computational capabilities, methods and approaches traditionally associated with atomic and molecular physics can now be applied to biomolecular systems. The related research areas of the MBN group include the elucidation of fundamental physical mechanisms of such biomolecular processes as protein folding, radiation damage of biomolecules, association and dissociation of macromolecular complexes, etc. The size of the considered biomolecular systems is usually on the nanometer scale. Therefore, these studies are bundled with the group’s activity on the nanoscience front and receive a strong feedback from this interdisciplinary interconnection.

- Nanoscale phase transitions
