What: Many-body physics: Bose-Einstein condensation and superconductivity.
Abstract: The phenomenon of superconductivity has been discovered in 1911. Despite of over one hundred years of efforts and many Nobel prizes given to the research on superconductivity, still this remarkable effect can only be observed at low temperatures. All attempts to realize the room temperature superconductivity failed so far. Meanwhile, a similar phenomenon has been observed at a room temperature in 2007: the Bose-Einstein condensation of electrically neutral crystal quasiparticles, exciton-polaritons. At certain conditions tens of thousands of these quasiparticles may be accumulated in a single quantum state characterised by one fixed energy, phase and velocity. If the same would happen to charged particles, we would have a superconductivity at room temperature. In this talk I will analyze the possible ways of realisation of high temperature superconductivity mediated by Bose-Einstein condensates of excitons and exciton-polaritons. I will remind the concept of exciton mediated superconductivity proposed by Ginzburg and Bardeen in 1970s. The recent discoveries of high temperature Bose-Einstein condensation offer a new chance for realisation of this revolutionary concept.
