Lovelock theory, black holes and holography |
Speaker: | Jose Edelstein (University of Santiago de Compostela) |
Abstract: | Lovelock theory is the natural extension of general relativity to higher
dimensions. It can be also thought of as a toy model for ghost-free higher curvature
corrections in gravitational theories. It generically admits a family of AdS vacua, most
(but not all) of them supporting black hole solutions that display interesting features.
This provides an appealing arena to explore different holographic aspects in the context of
the AdS/CFT and the fluid/gravity correspondences. |

Topological defects in polariton quantum fluids |
Speaker: | Benoit Deveaud-Plédran (École polytechnique fédérale de Lausanne EPFL) |
Abstract: | Microcavity polaritons are novel quasiparticles resulting from the strong coupling between photons, confined in an optical cavity, and excitons, confined in a quantum well. Polaritons are the half-light / half-matter bosons, and they cary a spin. Polaritons have recently been shown to undergo Bose Einstein condensation and superfluid properties of polariton fluis have been demonstrated.
In this talk, I will present some results on the observation and dynamical properties of topological excitations of a polariton fluid. In particular, I will describe the observation of quantized vortices, half-quantized vortices, vortex streets, spin vortices and dark solitons. The variety of the typology observed in a very short amount of time comes in fact from the very short lifetime of polaritons that leak out of the cavity in the form of photons, allowing a direct observation of their phase properti |

Correlation effects in transport through multi-level carbon nanotube quantum dots |
Speaker: | Dr. Sabine Andergassen (Vienna University , Faculty of Physics) |
Abstract: | We investigate the effect of Coulomb interactions on the electronic transport through quantum dots providing theoretical understanding for recent experiments on carbon nanotubes. The level structure is characterized by shells consisting of two doublets with strong- and weak tunnel couplings to the leads in absence of magnetic field. In addition to the Kondo ridges at zero field, the crossings of levels originating from different shells give rise to Kondo ridges at finite magnetic field. The observed bending with respect to the Kondo ridges at zero field turns out be a consequence of the magnetic-field dependence of the level-reservoir coupling strengths. Using the functional renormalization-group approach, we reproduce the features of the linear conductance measurements as a function of the applied gate voltage and magnetic field. In particular the bending of the Kondo ridges at finite magnetic field is traced back to the renormalization of the couplings. |

High Precision Mass Measurements of Rare Isotopes for Tests of ”Fundamental Symmetries |
Speaker: | Stephan Ettenauer (Harvard University) |
Abstract: | To date, Vud of the Cabibbo-Kobayashi-Maskawa quark mixing matrix is
most precisely determined from superallowed nuclear ß-decays. In addition
to half-life, branching ratio, and transition energy (called Q-value)
of a superallowed decay, theoretical corrections have to be considered
to extract Vud. Among those, the isospin symmetry breaking corrections,
δC, show discrepancies between different theoretical models, which
are critical to be resolved. |
