Planar Gunn diodes based on doped GaN active layers with different geometries have been fabricated and characterized. Gunn oscillations have not been observed due to the catastrophic breakdown of the diodes for applied voltages around 20–25 V, much below the bias theoretically needed for the onset…

Space weathering influence on Ryugu’s IR signature: insights from nanoscale vibrational spectroscopy in the STEM

Sylvain Laforet, Hugues Leroux, Corentin Le Guillou, Francisco de la Peña, Maya Marinova, Damien Jacob, Jean-Christophe Viennet, Bahae-Eddine Mouloud, Daniel Hallatt, Adrien Teurtrie, Mario Pelaez Fernandez, Mike Walls, L. Galvao-Tizei, David Troadec

JAXA’s Hayabusa2 mission brought back 5.4 g of material from the surface of the carbonaceous asteroid Ryugu. Some grains show evidence of a modified surface attributed to space-weathering effects [1], which result from solar-wind irradiation and/or micrometeoroid bombardment. In collaboration with…

A Quantum Annealing Solution to the Job Shop Scheduling Problem

Riad Aggoune, Samuel Deleplanque

We consider in this paper the job shop scheduling problem. We first present a mathematical formulation of the problem, namely a disjunctive model. Then, we show how the model can be reformulated as a Quadratic Unconstrained Binary Optimization (QUBO) problem, that can be solved by an analog quantum…

Solving 3SAT and MIS Problems with Analog Quantum Machines

Samuel Deleplanque

This work considers the use of analog quantum machines to solve the boolean satisfiability problem 3SAT by taking Quadratic Unconstrained Binary Optimization models (QUBO) as input. With the aim of using real quantum computers instead of emulators to solve instances of the problem, we choose the D-…

[Invited] Design, Fabrication and Dynamic Testing of Insect-Inspired Nano Air Vehicles

Sébastien Grondel, Damien Faux, Marguerite de La Bigne, Ahmad Itawi, Marie Zwingelstein, Sofiane Ghenna, Caroline Soyer, Eric Cattan, Olivier Thomas

When developing a flying robot on the insect scale, all process must be developed from scratch as usual macroscale solutions for the design and fabrication would not satisfy the extreme mass and power limitations. In this context, the aims of this work are to outline the proposed bioinspired…
