Background and Purpose

Recent experiments have demonstrated several electron sources that can controllably inject single or few particles into an electric circuit. This is a novel field of research that is at the very forefront of current investigations of quantum coherent electron transport in low temperature, on-chip electron transport. Experimentally the domain requires mastery of high-frequency measurements and theoretically it represents a push into largely unexplored dynamic electron transport theory. Different sources which are currently under investigation are emitters based on quantum pumps, mesoscopic capacitors or trains of Lorentzian pulses applied to a sample. Of interest is the full quantum statistics of the emitters which permits to assess their fidelity. The advent of single particle emitters opens unprecedented control in the generation and manipulation of quantum coherent few electron states. The generation of two-particle states has recently been successfully demonstrated. For such coherent multiparticle states the synchronization of single particle emitters becomes important as well as the coherence of the emitted states. The workshop is to present some of the key experimental and theoretical advances in this young field.

Participants

Participation is by invitation only. Please contact physics-events-physicsdays@forums.warwick.ac.uk if you think this workshop looks as if it would be of interest to you. Normally, we would be happy to accept self-invitations, but will not be able to pay for any expenses in this case.

The symposium will start at 09:30 a.m. on 5th June 2013, at the University of Warwick. Note that the university is located at the outskirts of Coventry and not in Warwick. See http://www2.warwick.ac.uk/about/visiting/ for travel details and http://www2.warwick.ac.uk/about/visiting/maps/ for maps of the central campus. In case you come by car, parking is available for delegates at car park 15.

This list of participants is accurate as of 04.06.2013.
