Egalisation modale des salles avec des absorbeurs électroacoustiques

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

L’égalisation du champ sonore aux basses fréquences (égalisation modale) est un véritable défi dans les salles d’enregistrement ou dédiées aux systèmes audio. Les résonances modales conduisent à une distribution irrégulière en espace et en fréquence de l’é ...

Gas Turbine: Optimization of Energy Production and High Efficiency by Using Power Electronics

Alfred Rufer, Aziza Benaboud

The use of gas turbines in the power generation industry has been increasing. Their demand represents more than 50% of the world market of thermal power plants. Electric power generators using gas turbines as power sources are connected to the turbines thr ...

Magnetic remanence in single atoms

Harald Brune, François Patthey, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Zeljko Sljivancanin, Aparajita Singha, Romana Baltic

A permanent magnet retains a substantial fraction of its saturation magnetization in the absence of an external magnetic field. Realizing magnetic remanence in a single atom allows for storing and processing information in the smallest unit of matter. We s ...

Probing the coupling between a doublon excitation and the charge-density wave in TaS2 by ultrafast optical spectroscopy

Arnaud Magrez, Fabrizio Carbone, Edoardo Baldini, Helmuth Berger, Andreas Helmut Christian Mann, Ahmad Odeh

Recently, the switching between the different charge-ordered phases of 1T-TaS2 has been probed by ultrafast techniques, revealing unexpected phenomena such as "hidden" metastable states and peculiar photoexcited charge patterns. Here, we apply broadband pu ...

Spatial multistability induced by cross interactions of confined polariton modes

Benoît Marie Joseph Deveaud, Daniel Oberli, François Morier-Genoud, Marcia Portella Oberli, Claudéric Ouellet-Plamondon, Grégory Chilpéric Sallen

We demonstrate the occurrence of spatial multistability using laterally confined microcavity exciton-polaritons. By coherently exciting with a blue detuned laser a series of confined polariton modes, we investigate the effects of multistability on the tran ...

Partially gated lateral tunnel field effect transistor for optical applications

Mihai Adrian Ionescu, Nilay Dagtekin

Silicon-based partially gated tunnel FETs are characterized under optical and electrical excitation. Most significant outcomes of the experiments are (1) unique characteristics, namely, light induced negative transconductance and optically tunable output r ...

Broadband excitation in solid-state NMR using interleaved DANTE pulse trains with N pulses per rotor period

Geoffrey Bodenhausen, Diego Carnevale, Simone Ulzega

We analyze the direct excitation of wide one-dimensional spectra of nuclei with spin I = 1/2 or 1 in rotating solids submitted to pulse trains in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE), either with one short rotor-s ...

Simulation of Electrical Discharge Initiated by a Nanometer-Sized Probe in Atmospheric Conditions

Jürgen Brugger, Yuan Ma

In this paper, a two-dimensional nanometer scale tip-plate discharge model has been employed to study nanoscale electrical discharge in atmospheric conditions. The field strength distributions in a nanometer scale tip-to-plate electrode arrangement were ca ...

Broadband excitation in solid-state NMR of paramagnetic samples using Delays Alternating with Nutation for Tailored Excitation ('Para-DANTE')

Geoffrey Bodenhausen, Diego Carnevale

This Letter shows that interleaved sequences of short pulses in the manner of 'Delays Alternating with Nutation for Tailored Excitation' (DANTE) with N = 1,2,3 . . . equidistant pulses per rotor period extending over K rotor periods can be used to excite, ...
