Inverse saffman-taylor experiments with particles lead to capillarity driven fingering instabilities

Ilyesse Bihi, Michael Baudoin, Jason E. Butler, Christine Faille, Farzam Zoueshtiagh

Using air to displace a viscous fluid contained in a Hele-Shaw cell can create a fingering pattern at the interface between the fluids if the capillary number exceeds a critical value. This Saffman-Taylor instability is revisited for the inverse case of a viscous fluid displacing air when partially…

Bulk acoustic wave transformer employing periodically polled array of piezoelectric rods

Victor Plessky, Ventsislav Yantchev, C. Granger, Anne-Christine Hladky

Multilayer bulk acoustic wave transformer employing a periodical array of piezoelectric rods with alternating polarization is experimentally demonstrated for the first time. Voltage transformation coefficient in excess of 6 was measured at a frequency of 150kHz, providing thus a solid experimental…

Electronic structure investigation of Al0.7Ga0.3As/GaAs nanometric heterostructures by Kelvin force microscopy

Sylvain Pouch, Francois Triozon, Nicolas Chevalier, Thierry Melin, Yann Michel Niquet, Lukasz Borowik

Kelvin force microscopy provides a spatially resolved measurement of the surface potential, which is related to the energetic band structure of a material. The goal of this work is to investigate the surface potential on Al0.7Ga0.3As and GaAs heterostructures with a decreasing layer thickness up to…

METASTABILITY OF FINITE STATE MARKOV CHAINS: A RECURSIVE PROCEDURE TO IDENTIFY SLOW VARIABLES FOR MODEL REDUCTION

Claudio Landim, T. Xu

Consider a sequence (η N (t) : t ≥ 0) of continuous-time, irreducible Markov chains evolving on a fixed finite set E. Denote by R N (η, ξ) the jump rates of the Markov chain η N t , and assume that for any pair of bonds (η, ξ),

Mode-hopping suppression in long Brillouin fiber laser with non-resonant pumping

Gwennaël Danion, Ludovic Frein, Denis Bacquet, Grégoire Pillet, Stéphanie Molin, Loïc Morvan, Guillaume Ducournau, Marc Vallet, Pascal Szriftgiser, Mehdi Alouini

We propose a reliable method for stabilizing narrow linewidth Brillouin fiber lasers with non-resonant pumping. Mode-hopping is suppressed by means of a phase-locked loop that locks the pump-Stokes detuning to a local radio-frequency (RF) oscillator. Stable single-mode operation of a 110-m-long…
