WP1: Local superconductivity and Bose-Einstein Condensation in Graphite

Within the project ROBOCON we are planning to explore superconducting properties
of sulfur-doped and structurally disordered patches on HOPG surface and isolated
graphene by means of local probe measurements.We suppose understand formation
of excitonic gap in graphite and test it appearance an high (room) temperatures

Task 1.1 : Experimental study of transport phenomena in graphite in ultra-high magnetic field (10-50T), phase and multifractal analysis of observed peculiarities
Task 1.2: Study of excitonic gap local bose-pairs formation
Task 1.3: Theory of semimetal properties and of unconventional Quantum Hall effect in graphite, based on Dirac- and normal charge carriers
Task 1.4 Study of possibility of Bose condensation and another quantum phenomena in Graphite at room temperatures

WP2: Exciton - Polariton Bose-Einstein Condensation

Basing on the recently discovered Bose-Einstein condensation of exciton-polariton
pairs predict and test condition for realization of room temperature optically induced
superconductivity and spin superfluidity.

Task 2.1 : Show experimentally the formation of quadron-polaritons obeying bosonic statistics.
Task 2.2: Study the spatial-temporal dynamics of superfluids of exciton- and quadron-polaritons in microcavities.
Task 2.3: Observe experimentally the light-induced superconductivity in microcavities
Task 2.4: Observe experimentally superfluid polariton spin currents

WP3: Bose-Einstein Condensation in Oxides

Basing on the already studied superconducting BEC transitions in Sr- and W-based
oxides in vicinity of Metal-Insulator crossover, try to increase the critical temperature
either by variation of chemical composition or by reducing the dimensionality of the
system, preparing samples in form of thin films or superlattices.

Task 3.1 Preparation of SrTiO3 and LaAlO3 based ceramics, films and superlattices
Task 3.2: Preparation of W-based oxide films
Task 3.3 Dielectric, transport and magnetic characterization of the above samples
Task 3.4 Modeling and theoretical explication of the discovered phenomena
