|Basic activity directions
||Investigation effects of randomly distributed impurities on the surface states and surface current in a topological insulator, as well as their effects in a topological superconductor on the critical temperature and Majorana fermions are planned to perform.
|Main scientific achievements
||Quasi-one-dimensional structure of superconducting wires is transformed into topological phase in the presence of spin-orbit interaction and external magnetic field . In this case, Majorana fermions, emerging at the end-point of the structure, result in a fractional Josephson current, which flows over the edge of the system. Dependence of Josephson current on the spin-orbit interaction constant and on the magnetic field is found for a Josephson contact of two topological superconductor separated by delta-like potential barrier.
