SEMINAR ABSTRACT:

An indirect exciton is a bound pair of an electron and a hole confined in spatially separated layers. Due to their long lifetimes, indirect excitons can cool down below the temperature of quantum degeneracy. This gives an opportunity to study cold exciton gases. We will present spontaneous coherence and condensation, spatial ordering, and spin currents in a cold excitons gas.
Indirect excitons are dipoles and their energy can be controlled by voltage. This gives an opportunity to build devices, which operate with excitons in place of electrons. We will present a proof of principle demonstration of excitonic circuit devices.
The energy control by voltage also gives an opportunity to create a variety of potential landscapes for indirect excitons and use them as a tool for studying basic properties of excitons. We will present spontaneous coherence and condensation of excitons in a trap.
