High-impedance frequency-agile THz dipole antennas using graphene

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

The concept and analysis of a THz frequency-reconfigurable antennas using graphene are presented. The antennas exploit dipole-like plasmonic resonances that can be frequency-tuned on large range via the electric field effect in a graphene stack. In additio ...

Deformable Droplets, a numerical account

François Gallaire, Mathias Nagel

We simulate confined droplets in microchannels by depth-averaged equations solved by a boundary element method. The retarding effect due to film formation is absent in the depth-averaged approach and added by a nonlinear boundary condition. Although deform ...

Optofluidic Microstructures Containing Liquid Crystals

Andreas Vasdekis, Luciano De Sio, Marilisa Romito

We report our recent efforts on the realization and characterization of a conductive polydimethylsiloxane (PDMS) microstructure containing liquid crystals (LC). The sample has been realized by means of a layer by layer strategy. An indium tin oxide (ITO) l ...

On field effect studies and superconductor-insulator transition in high-Tc cuprates

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

We summarize previous field effect studies in high-T (c) cuprates and then discuss our method to smoothly tune the carrier concentration of a cuprate film over a wide range using an applied electric field. We synthesized epitaxial one-unit-cell thick films ...

SPDC based single-photon source with frequency up-conversion multiplexed architecture

Vincent Frédéric Camus

We describe a single-photon source based on an array of spontaneous parametric down-conversion (SPDC) modules multiplexed by an integrated structure composed of electro-optic switches and delay wave-guides. The suggested optical device allows to increase t ...

Cell Polarization: Mechanical Switch for a Chemical Reaction

Anterior-posterior polarity in the Caenorhabditis elegans zygote depends on two groups of PAR proteins, as well as on cortical flow. Recent work now demonstrates that this polarization results from a transition in a bistable reaction-diffusion system of PA ...

Electric field effect in graphite crystallites

Klaus Kern, Marko Burghard, Kannan Balasubramanian, Adarsh Singh Sagar

Graphite is a highly anisotropic crystal with a quasi-two-dimensional electronic structure exhibiting high intrinsic charge carrier mobility. Here, we investigate the effect of an electric field on the resistance of individual graphite crystallites with a ...

Alkaline niobate nanowires as opto-mechanical probes

Aleksandra Radenovic, Fabrizia Dutto

Perovskite alkaline niobate (XNbO3) nanowires are attracting lots of attention having a variety of interesting properties such as significant nonlinear optical response, pronounced birefringence, considerable piezoelectric, pyroelectric, photorefractive, a ...

Differential Branching Fraction and Angular Analysis of the Decay B-0 -> K*(0)mu(+)mu(-)

Jian Wang, Olivier Schneider, Yi Zhang, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Christophe Salzmann, Lei Zhang, Jessica Prisciandaro, Mark Tobin, Minh Tâm Tran, Niko Neufeld, Matthew Needham, Marc-Olivier Bettler, Greig Alan Cowan, Vladislav Balagura, Cédric Potterat, Plamen Hristov Hopchev, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Barinjaka Rakotomiaramanana, Pierre Jaton, Joël Bressieux, Raluca Anca Muresan, Johan Luisier, Anne Keune, Albert Puig Navarro, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin, Hans Dijkstra, Gerhard Raven, Peter Clarke, Frédéric Teubert, Giovanni Carboni, Victor Coco, Wenyu Zhang

The angular distributions and the partial branching fraction of the decay B-0 -> K*(0)mu(+)mu(-) are studied by using an integrated luminosity of 0.37 fb(-1) of data collected with the LHCb detector. The forward-backward asymmetry of the muons, A(FB), the ...
