Finite-dimensional vestige of spinodal criticality above the dynamical glass transition
Ludovic Berthier, Patrick Charbonneau, Joyjit Kundu
Finite-dimensional signatures of spinodal criticality are notoriously difficult to come by. The dynamical transition of glass-forming liquids, first described by mode-coupling theo…
Transparent Experiments: Releasing Data from Mechanical Tests on Three Dimensional Hydrogel Sphere Packings
Jonathan Barés, Nicolas Brodu, Hu Zheng +1
We describe here experiments on the mechanics of hydrogel particle packings from the Behringer lab, performed between 2012 and 2015. These experiments quantify the evolution of all…
CVD diamond single crystals with NV centres: a review of material synthesis and technology for quantum sensing applications
J. Achard, V. Jacques, A. Tallaire
Diamond is a host for a wide variety of colour centres that have demonstrated outstanding optical and spin properties. Among them, the nitrogen-vacancy (NV) centre is by far the mo…
New interaction potentials for borate glasses with mixed network formers
Siddharth Sundararaman, Liping Huang, Simona Ispas +1
We adapt and apply a recently developed optimization scheme used to obtain effective potentials for aluminosilicate glasses to include the network former boron into the interaction…
Harnessing near-field thermal photons with efficient photovoltaic conversion
C Lucchesi, D. Cakiroglu, J. -P Perez +4
A huge amount of thermal energy is available close to material surfaces in radiative and non-radiative states, which can be useful for matter characterization or for energy devices…
Brittle yielding of amorphous solids at finite shear rates
Murari Singh, Misaki Ozawa, Ludovic Berthier
Amorphous solids display a ductile to brittle transition as the kinetic stability of the quiescent glass is increased, which leads to a material failure controlled by the sudden em…
On an existence theory for a fluid-beam problem encompassing possible contacts
Jean-Jérôme Casanova, Céline Grandmont, Matthieu Hillairet
In this paper we consider a coupled system of pdes modelling the interaction between a two--dimensional incompressible viscous fluid and a one--dimensional elastic beam located on…
Enabling Machine Learning Across Heterogeneous Sensor Networks with Graph Autoencoders
Johan Medrano, Fuchun Joseph Lin
Machine Learning (ML) has been applied to enable many life-assisting appli-cations, such as abnormality detection and emdergency request for the soli-tary elderly. However, in most…
H.E.S.S. and Fermi-LAT observations of PSR B1259-63/LS 2883 during its 2014 and 2017 periastron passages
H. E. S. S. Collaboration, H. Abdalla, R. Adam +222
PSR B1259-63/LS 2883 is a gamma-ray binary system consisting of a pulsar in an eccentric orbit around a bright Oe stellar-type companion star that features a dense circumstellar di…
Coarsening Dynamics in the Vicsek Model of Active Matter
Nisha Katyal, Supravat Dey, Dibyendu Das +1
We study the flocking model introduced by Vicsek in the "coarsening" regime. At standard self-propulsion speeds, we find two distinct growth laws for the coupled density and veloci…
Jones' Conjecture in subcubic graphs
Marthe Bonamy, François Dross, Tomáš Masařík +3
We confirm Jones' Conjecture for subcubic graphs. Namely, if a subcubic planar graph does not contain vertex-disjoint cycles, then it suffices to delete vertices to obta…
Demonstration of critical coupling in an active III-nitride microdisk photonic circuit on silicon
Farsane Tabataba-Vakili, Laetitia Doyennette, Christelle Brimont +11
On-chip microlaser sources in the blue constitute an important building block for complex integrated photonic circuits on silicon. We have developed photonic circuits operating in…
Non-linear damping of superimposed primordial oscillations on the matter power spectrum in galaxy surveys
Mario Ballardini, Riccardo Murgia, Marco Baldi +2
Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical models o…
Large-scale inference of correlation among mixed-type biological traits with phylogenetic multivariate probit models
Zhenyu Zhang, Akihiko Nishimura, Paul Bastide +5
Inferring concerted changes among biological traits along an evolutionary history remains an important yet challenging problem. Besides adjusting for spurious correlation induced f…
Disorder-induced phase transition in Dirac systems beyond the linear approximation
Sergey S. Krishtopenko, Mauro Antezza, Frédéric Teppe
By using the self-consistent Born approximation, we investigate disorder effect induced by the short-range impurities on the band-gap in two-dimensional Dirac systems with the high…
Global properties of the growth index: mathematical aspects and physical relevance
R. Calderon, D. Felbacq, R. Gannouji +2
We analyze the global behaviour of the growth index of cosmic inhomogeneities in an isotropic homogeneous universe filled by cold non-relativistic matter and dark energy (DE) with…
Role of fluctuations in the yielding transition of two-dimensional glasses
Misaki Ozawa, Ludovic Berthier, Giulio Biroli +1
We numerically study yielding in two-dimensional glasses which are generated with a very wide range of stabilities by swap Monte-Carlo simulations and then slowly deformed at zero…
Many-particle effects in optical transitions from zero-mode Landau levels in HgTe quantum wells
S. S. Krishtopenko, A. M. Kadykov, S. Gebert +9
We report on the far-infrared magnetospectroscopy of HgTe quantum wells with inverted band ordering at different electron concentrations. We particularly focus on optical transitio…
Optimal checkpointing for heterogeneous chains: how to train deep neural networks with limited memory
Julien Herrmann, Olivier Beaumont, Lionel Eyraud-Dubois +3
This paper introduces a new activation checkpointing method which allows to significantly decrease memory usage when training Deep Neural Networks with the back-propagation algorit…
A very-high-energy component deep in the Gamma-ray Burst afterglow
H. Abdalla R. Adam F. Aharonian F. Ait Benkhali E. O. Anguener M. Arakawa, C. Arcaro, C. Armand +219
Gamma-ray bursts (GRBs) are brief flashes of gamma rays, considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typicall…
