Optomechanical studies of a nanobeam coupled to a superconducting microwave cavity

S. Kumar, D. Cattiaux, X. Zhou, E. Collin, A. Fefferman

The low temperature dissipation in glass nanomechanical resonators is dominated by low energy exci- tations, i.e., atomic scale entities that are modeled as TLSs (tunneling two level systems). These TLSs couple to vibrational modes of nanomechanical resonators (NEMS) made of amorphous materials.…

Nonlinear Self-Induced Oscillations in Microwave Optomechanics

D. Cattiaux, X Zhou, R. Gazizulin, L. Mercier de Lépinay, S. Kumar, A. Luck, M. Sillanpaa, A. Armourd, A. Fefferman, E. Collin

We report on self-sustained oscillations studied on geometrically different mechanical devices embedded in a microwave optomechanical setup. A strong blue-detuned pump signal (at a frequency shifted up from the cavity by the mechanical frequency) triggers the parametric instability. Two different…

Theoretical Study of Intersubband Absorption Coefficient in GaNAsBi/GaAs Quantum Well Structures

Lynda Chenini, Abdelkader Aissat, Jean-Pierre Vilcot

This work focuses on the study and simulation of a based intersubband GaNAsBi/GaAs quantum well structure. The effect of different physical and optical parameters has been explored. The band gap of GaNAsBi is calculated using the band anti-crossing model. The influence of the composition and the…

A robust method for MR image segmentation and multiple scleroses detection

H. Zouaoui, Abdelouahab Moussaoui, Mourad Oussalah, Abdelmalik Taleb-Ahmed

In the present article, we propose a new approach for the segmentation of the MR images of the Multiple Sclerosis (MS). The Magnetic Resonance Imaging (MRI) allows the visualization of the brain and it is widely used in the diagnosis and the follow-up of the patients suffering from MS. Aiming to…

Particle assembly with synchronized acoustic tweezers

Zhixiong Gong, Michael Baudoin

The contactless selective manipulation of individual objects at the microscale is powerfully enabled by acoustical tweezers based on acoustical vortices [M. Baudoin et al., Sci. Adv. 5, eaav1967 (2019)]. Nevertheless, the ability to assemble multiple objects with these tweezers has not been…

Comparative Study on the Impact of Growth Conditions on the Physiology and the Virulence of Pseudomonas aeruginosa Biofilm and Planktonic Cells

Simon Oussama Khelissa, Marwan Abdallah, Charafeddine Jama, Alexandre Barras, Nour-Eddine Chihib

The aim of the present work was to study and compare the effect of growth temperature (20, 30, and 37 degrees C) and surface type (stainless steel and polycarbonate) on the production of virulence factors, such as proteases and siderophores, and the risk of surface contamination associated with…

Agent-based model of multicellular tumor spheroid evolution including cell metabolism

Fabrizio Cleri

Computational models aiming at the spatio-temporal description of cancer evolution are a suitable framework for testing biological hypotheses from experimental data, and generating new ones. Building on our recent work (J. Theor. Biol. 389, 146 (2016)) we develop a 3D agent-based model, capable of…

Stochastic thermodynamics of holonomic systems

Stefano Giordano

Stochastic thermodynamics is a recently introduced approach to deals with small systems in contact with one or more thermal baths. This theory has been applied to systems of unconstrained particles to investigate the role of the thermodynamics principles in micro-and nano-scale systems and to…
