Transport Inefficiency in Branched-Out Mesoscopic Networks: An Analog of the Braess Paradox

M. G. Pala, S. Baltazar, Peng Liu, Hermann Sellier, B. Hackens, F. Martins, Vincent Bayot, X. Wallart, L. Desplanque, Serge Huant

We present evidence for a counterintuitive behavior of semiconductor mesoscopic networks that is the analog of the Braess paradox encountered in classical networks. A numerical simulation of quantum transport in a two-branch mesoscopic network reveals that adding a third branch can paradoxically…

Joint Carrier Frequency Offset and Channel Estimation for OFDM Systems via the EM Algorithm in the Presence of Very High Mobility

Eric Pierre Simon, Laurent Ros, Hussein Hijazi, Mounir Ghogho

In this paper, the problem of joint carrier frequency offset (CFO) and channel estimation for OFDM systems over the fast time-varying frequency-selective channel is explored within the framework of the expectation-maximization (EM) algorithm and parametric channel model. Assuming that the path…

Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes

John Cuffe, Emigdio Chavez, Andrey Shchepetov, Pierre-Olivier Chapuis, El Houssaine El Boudouti, Francesc Alzina, Timothy Kehoe, Jordi Gomis-Bresco, Damian Dudek, Yan Pennec, Bahram Djafari-Rouhani, Mika Prunnila, Jouni Ahopelto, Clivia. M. Sotomayor Torres

We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group velocities of the fundamental flexural mode by more than one order of magnitude compared to bulk values. The…

A memristive nanoparticle/organic hybrid synapstor for neuroinspired computing

F. Alibart, S. Pleutin, O. Bichler, C. Gamrat, T. Serrano-Gotarredona, B. Linares-Barranco, D. Vuillaume

A large effort is devoted to the research of new computing paradigms associated to innovative nanotechnologies that should complement and/or propose alternative solutions to the classical Von Neumann/CMOS association. Among various propositions, Spiking Neural Network (SNN) seems a valid candidate…
