Aims and ScopeNoise and fluctuations are results of stochastic processes that govern many physical phenomena and originate from both classical and quantum sources. Noise has often detrimental effects on the transport properties of low-dimensional structures such as nano-scale quantum dots or small superconducting junctions, but it has also been recognized as a powerful tool to extract detailed information on the complicated interaction processes in non-equilibrium systems in the quantum regime. In particular, high order noise cumulants, full counting statistics (FCS), and frequency dependent non-equilibrium noise spectra have emerged quite recently as fruitful transport theory concepts, and we now witness a growing trend to extend these concepts and to test them experimentally. For example, large noise cumulants display striking universal oscillations as a function of measurement time - a phenomenon that appears due to mathematical properties of high-order derivatives in the complex plane and that has been confirmed experimentally very recently in quantum dot experiments. Currently open issues in non-equilibrium noise for quantum transport concern the combined presence of quantum coherence, strong interactions and dissipation (an important aspect for solid state qubits), and noise in time-dependent and non-Markovian quantum transport.
The main emphasis shall be on foundations, concepts, and theoretical techniques, but a number of important experimental developments shall be represented as well. It is fair to say that the present status of the field is still much dominated by theoretical work, but recently a growing number of successful experiments has brought this into a more balanced shape. The talks (60 min incl. discussions) will be given by invited speakers who belong to the leading experts in their field of research. Participants can contribute with a poster, there will be one poster session and a `Best Poster Award'. Invited Speakers, Talks (preliminary titles)
RegistrationThe Seminar will have duration of two and a half days (arrival Sunday May 17 evening, departure Wednesday May 20 after lunch). The total number of participants is limited to 60, there are no accommodation and registration fees. For registration, please send an email to weh431@itp.physik.tu-berlin.de until March 15, 2009, including the following information: name, institute address, status (student/PostDoc etc.), title of poster contribution, research interests (very short, 2-3 keywords only). You will receive notification about acceptance by the end of March. Preliminary Programme
