PHYSICS COLLOQUIUM
« Electron counting in quantum dots in and out of equilibrium »
Prof. Klaus Ensslin
Solid State Physics Laboratory, ETH Zurich, 8093 Zurich, Switzerland

Electron transport through quantum dots is governed by Coulomb blockade. Using a nearby quantum point contact the time-dependent charge flow through quantum dots can be monitored on the basis of single electrons. This way electron transport has been investigated in equilibrium as well as out of equilibrium. Recently it has become possible to experimentally verify the fluctuation theorem.
The talk will also address electron counting experiments in grapheme.

Une verrée en compagnie du conférencier sera offerte après le colloque.
