A tutorial survey on waves propagating in periodic media: electronic, photonic and phononic crystals. Perception of Bloch theorem in both real and Fourier domains

Joseph Gazalet, Samuel Dupont, Jean-Claude Kastelik, Quentin Rolland, Bahram Djafari-Rouhani

This paper presents a review of the most widely-used methods in order to determine the structure of eigenmodes propagating in periodic materials. Both real and Fourier domain methods are outlined. The basic concepts such as eigensolutions and their k-labeling, reciprocal lattice, Brillouin zones,…

Ultrafast short-range disordering of femtosecond-laser-heated warm dense aluminum

P. M. Leguay, A. Levy, B. Chimier, F. Deneuville, D. Descamps, C. Fourment, C. Goyon, S. Hulin, S. Petit, O. Peyrusse, J. J. Santos, P. Combis, B. Holst, V. Recoules, P. Renaudin, L. Videau, F. Dorchies

We have probed, with time-resolved x-ray absorption near-edge spectroscopy (XANES), a femtosecond-laser-heated aluminum foil with fluences up to 1 J/cm2. The spectra reveal a loss of the short-range order in a few picoseconds. This time scale is compared with the electron-ion equilibration time,…

Airway reopening through catastrophic events in a hierarchical network

Michael Baudoin, Yu Song, Paul Manneville, Charles N. Baroud

When you reach with your straw for the final drops of a milkshake, the liquid forms a train of plugs that flow slowly initially because of the high viscosity. They then suddenly rupture and are replaced with a rapid airflow with the characteristic slurping sound. Trains of liquid plugs also are…

Doped semiconductor nanocrystal junctions studied by Kelvin probe and non-contact atomic force microscopy

Lukasz Borowik, Thuat Nguyen-Tran, D. Deresmes, Heinrich Diesinger, Pere Roca I Cabarrocas, Thierry Melin

Semiconductor junctions are the basis of electronic and photovoltaic devices. Here, we investigate junctions formed from highly doped (ND~10^20-10^21 cm-3) hydrogen-passivated silicon nanocrystals (NCs) in the 2-50nm size range, using non-contact atomic force microscopy coupled to Kelvin probe…

Scanning Gate Spectroscopy of transport across a Quantum Hall Nano-Island

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

We explore transport across an ultra-small Quantum Hall Island (QHI) formed by closed quan- tum Hall edge states and connected to propagating edge channels through tunnel barriers. Scanning gate microscopy and scanning gate spectroscopy are used to first localize and then study a single QHI near a…

Planning the electron traffic in semiconductor networks: A mesoscopic analog of the Braess paradox encountered in road networks

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

By combining quantum simulations of electron transport and scanning-gate microscopy, we have shown that the current transmitted through a semiconductor two-path rectangular network in the ballistic and coherent regimes of transport can be paradoxically degraded by adding a third path to the network…

Assisted Channel Estimation with Dynamic Allocation Pilot Subcarriers for OFDM Communications

Boudali Ouarzazi, Atika Rivenq, Iyad Dayoub, Marion Berbineau

In this paper, a transmission system based on OFDM (Orthogonal Frequency Division Multiplexing) technique and channel estimation is proposed. The idea is to enhance the assisted channel estimation without data rate loss. A solution based on frequency diversity is proposed. With the same number of…

Blind primary user identification in MIMO cognitive networks

A. Ghosh, W. Hamouda, Iyad Dayoub

Early detection of primary users presence is one of the most important tasks for cognitive communication. Also, in cognitive settings cognitive nodes may receive signals from primary users and from other cognitive users simultaneously. For such scenario, we propose primary user signal detection…
