, 2003 Thermoelectric effects are studied in an Aharonov-Bohm (AB) interferometer with an embedded quantum dot in the Kondo regime. The AB flux-dependent transmission probability has an asymmetrical shape arising from the Fano interference between the direct ...

Supersymmetry breaking as the origin of flavor
, 2004 We present an effective flavor model for the radiative generation of fermion masses and mixings based on a SU(5)xU(2) symmetry. We assume that the original source of flavor breaking resides in the supersymmetry breaking sector.

Localization Properties of the Periodic Random Anderson Model
, 1997 We consider diagonal disordered one-dimensional Anderson models with an underlying periodicity. We assume the simplest periodicity, i.e., we have essentially two lattices, one that is composed of the random potentials and the other of non-random ...

Crafting zero-bias one-way transport of charge and spin
, 2016 We explore the electronic structure and transport properties of a metal on top of a (weakly coupled) two-dimensional topological insulator. Unlike the widely studied junctions between topological non-trivial materials, the systems studied here allow for ...

Minimal Flavour Violation and Beyond
, 2007 Starting from the effective-theory framework for Minimal Flavour Violation, we give a systematic definition of next-to-minimal (quark) flavour violation in terms of a set of spurion fields exhibiting a particular hierarchy with respect to a small ...

E-mobility according to VDL Bus and Coach
AUTOBUSY – Technika, Eksploatacja, Systemy Transportowe, 2018 In the recent years electromobility is an important factor of achieving goals of European transport policy for the first half of the 21st century. Using electric buses in the public transport allows to reduce the use of petroleum-derived fuels and emission of exhaust and greenhouse gases. Bus manufacturers are introducing changes to products strategies

Oil & Gas Science and Technology, 2006 Les compagnies pétrolières ont un réel besoin d'évaluer correctement les cimentations de leurs puits : l'étanchéité entre les différentes zones est-elle assurée? Pour ce faire, les outils soniques et ultra-soniques ont été mis au point.
