[Read More]Single-Cooper-pair device based on quantum phase slips in superconducting nanowire
Tuesday 6 March 2012 at 3pm Room "Rémy Lemaire" K 223 (1st floor) Building K, Institut Néel / CNRS Alexander ZORIN (Physikalisch-Technische Bundesanstalt of Braunschweig, Germany) We propose and realize a transistor-like superconducting circuit including two serially connected segments of a narrow nanowire joint by a wider segment with a capacitively coupled gate in...

[Read More]Quartet correlations between Cooper pairs in a mesoscopic double Josephson junction
Tuesday 7 February 2012 at 3pm Room "Rémy Lemaire" K 223 (1st floor) Building K, Institut Néel / CNRS Régis MELIN (Institut Néel) Two Josephson junctions separated by less than the superconducting coherence length involve higher order processes that can be quite sizeable for more transparent junctions. Those processes originate from crossed Andreev reflections (CAR), where...
[Read More]Antiferromagnetism of spin 1 boson : experimental study with ultracold sodium atoms
Tuesday 31 January 2012 at 3pm Room "Rémy Lemaire" K 223 (1st floor) Building K, Institut Néel / CNRS Fabrice GERBIER (Laboratoire Kastler Brossel, Paris) In this talk, I will present a set of experiments done at Laboratoire Kastler Brossel (ENS Paris) on the magnetic properties of ultracold bosons cooled well below the Bose-Einstein condensation temperature....
[Read More]Towards hybrid electron-photon quantum circuits
Tuesday 24 January 2012 at 3pm Room "Rémy Lemaire" K 223 (1st floor) Building K, Institut Néel / CNRS Takis KONTOS (Laboratoire Pierre Aigrain, Paris) An atom coupled to a harmonic oscillator is one of the most illuminating paradigms for quantum measurements and amplification. Recently, the joint development of artificial two-level systems and high finesse microwave...
[Read More]Strained HgTe: a textbook 3D topological insulator probed by magnetotransport
Tuesday 17 January 2012 at 3pm Room "Rémy Lemaire" K 223 (1st floor) Building K, Institut Néel / CNRS Laurent LEVY (Institut Néel) When growing HgTe on a CdTe substrate, bi-axial strain opens a gap in HgTe turning it from a semi metal into a topological insulator. We have performed low field and high field magneto-transport in this 3D topological...
[Read More]Manipulation of Dirac points in two-dimensional crystals
Tuesday 10 January 2012 at 3pm Room "Rémy Lemaire" K 223 (1st floor) Building K, Institut Néel / CNRS Gilles MONTAMBAUX (Laboratoire de Physique des Solides,Orsay) I consider several examples of 2D crystals where the low energy properties can be described with a 2 x 2 Hamiltonian with a spectrum exhibiting several Dirac cones. These cones are ...
