Indirect excitons (IX) are quasi-particles consisting of an electron and a hole bound by the attractive Coulomb interaction. These excitons can be excited in special GaAs double quantum well structures subject to an electric field. Contrary to conventional excitons in semiconductors, which have a lifetime typically below one nanosecond, IXs are long living with an electrically controlled lifetime, which can reach the microsecond range. Their long lifetimes and their strong interaction with photons make indirect excitons (IXs) ideal particles for applications in optoelectronics using quantum information.
The PDI is actively involved in the investigations of dipolar gases of indirect excitons in GaAs quantum well structures. We have previously demonstrated that IX packets can carry spin polarization and be transported by surface acoustic waves (SAWs) over long (100's of micrometers) distance on a semiconductor quantum well. The research is carried out with external partners, the Hebrew University of Jerusalem and the NEEL, Institute France.
Within the partnership with the Hebrew University of Jerusalem we are delighted to announce the MINERVA SCHOOL ON QUANTUM DIPOLAR GASES IN ATOMIC & CONDENSED MATTER SYSTEMS (DIP-QUANTUM 2017).
This unique interdisciplinary school brings together leading international experts, both theorists and experimentalists, on quantum dipolar gases, as well as young researchers and students from two communities: atomic physics and condensed-matter physics. The workshop will stimulate the exchange of ideas around this topic and thus create a framework for new collaborations in this interdisciplinary field of research. Initiating and motivating exchange of knowledge and ideas between the two communities to combine these complementary know-hows would hopefully lead to new and original research directions.
The school will cover the following topics:
The 3-day event will take place at the Institute of Advanced Studies at the Hebrew University in Jerusalem, Israel on 23-25th of October, 2017. It will host only around 40 participants, to have an intimate atmosphere within the beautiful, green, and peaceful campus of the Hebrew University.
