PHYSIKALISCHES KOLLOQUIUM Referent: Prof. Dr. Klaus Ensslin ETH Zürich Thema: Mesoscopic Thermodynamics Zeit und Ort: Dienstag, 7.6.2016, 16:40 Uhr Physikgebäude, Hörsaal PHY/C213, Haeckelstr. 3 Leiter: Prof. Dr. Roland Ketzmerick Kurzfassung: The second law of thermodynamics is one of the pillars of our understanding in modern physics. For nanostructures individual charge carriers may violate this law, while averages over many charging events agree with predictions for macroscopic systems. As nanostructures contain fewer and fewer carriers, fluctuations become ever more important and their understanding is at the heart of mesoscopic thermodynamics. In this talk I will show results on time-resolved single electron transport through semiconductor and graphene quantum devices. This technique allows to measure directional transport at zero applied bias and enables the test of fluctuation theorems that connect measured quantities in non-equilibrium situation to well-known equilibrium quantities. This work was done in collaboration with A. Hofmann, V. Maisi, C. Roessler, B. Kueng, and T. Ihn. Kurzbiographie: Klaus Ensslin is Professor of Physics at the Eidgenössische Technische Hochschule Zürich, Switzerland since 1995 and Director of the National Center for Competence in Research on “Quantum Science and Technology” since 2011. He studied physics at the University of Munich and the ETH Zürich. He carried out his Ph.D. work at the Max-Planck Institute for Solid State Research, Stuttgart. After a two-year postdoc at the University of California in Santa Barbara and four years at the Physics Department of the University of Munich he received his Habilitation. Mitglied von:
