Naturalness in Type II seesaw model and implications for physical scalars
Mohamed Chabab, Michel Capdequi-Peyranère, Larbi Rahili
In this paper we consider a minimal extension to the standard model by a scalar triplet field with hypercharge . This model relies on the seesaw mechanism which provides a con…
New determination of abundances and stellar parameters for a set of weak G-band stars
A. Palacios, G. Jasniewicz, T. Masseron +3
Weak G-band (wGb) stars are very peculiar red giants almost devoided of carbon and often mildly enriched in lithium. Despite their very puzzling abundance patterns, very few detail…
Gamma-Ray Bursts at high and very high energies
F. Piron
Gamma-Ray Bursts (GRBs) are extra-galactic and extremely energetic transient emissions of gamma rays, which are thought to be associated with the death of massive stars or the merg…
Quark Condensate from Renormalization Group Optimized Spectral Density
J. -L. Kneur, A. Neveu
Our renormalization group consistent variant of optimized perturbation, RGOPT, is used to calculate the nonperturbative QCD spectral density of the Dirac operator and the related c…
Hexagonal boron nitride is an indirect bandgap semiconductor
G. Cassabois, P. Valvin, B. Gil
Hexagonal boron nitride is a wide bandgap semiconductor with a very high thermal and chemical stability often used in devices operating under extreme conditions. The growth of high…
Homogenization near resonances and artificial magnetism in 3D dielectric metamaterials
Guy Bouchitté, Christophe Bourel, Didier Felbacq
It is now well established that the homogenization of a periodic array of parallel dielectric fibers with suitably scaled high permittivity can lead to a (possibly) negative freque…
Non-LTE iron abundances in cool stars: The role of hydrogen collisions
Rana Ezzeddine, Thibault Merle, Bertrand Plez
In the aim of determining accurate iron abundances in stars, this work is meant to empirically calibrate H-collision cross-sections with iron, where no quantum mechanical calculati…
Beyond in-phase and anti-phase coordination in a model of joint action
Daniele Avitabile, Piotr Słowiński, Benoit Bardy +1
In 1985 Haken, Kelso and Bunz proposed a system of coupled nonlinear oscillators as a model of rhythmic movement patterns in human bimanual coordination. Since then, the Haken-Kels…
Vacuum stability and supersymmetry at high scales with two Higgs doublets
Emanuele Bagnaschi, Felix Brümmer, Wilfried Buchmüller +2
We investigate the stability of the electroweak vacuum for two-Higgs doublet models with a supersymmetric UV completion. The supersymmetry breaking scale is taken to be of the orde…
Improved kernels for Signed Max Cut parameterized above lower bound on (r,l)-graphs
Luerbio Faria, Sulamita Klein, Ignasi Sau +1
A graph is signed if each edge is assigned or . A signed graph is balanced if there is a bipartition of its vertex set such that an edge has sign if and only if its…
Distributed thermal tasks on many-body systems through a single quantum machine
Bruno Leggio, Pierre Doyeux, Riccardo Messina +1
We propose a configuration of a single three-level quantum emitter embedded in a non-equilibrium steady electromagnetic environment, able to stabilize and control the local tempera…
Decay Constants of Heavy-Light Mesons from QCD
Stephan Narison
We summarize recently improved results for the pseudoscalar [1,2] and vector [3] meson decay constants and their ratios from QCD spectral sum rules where N2LO + estimate of the N3L…
The MiMeS Survey of Magnetism in Massive Stars: Introduction and overview
G. A. Wade, C. Neiner, E. Alecian +47
The MiMeS project is a large-scale, high resolution, sensitive spectropolarimetric investigation of the magnetic properties of O and early B type stars. Initiated in 2008 and compl…
Competition between electric field and magnetic field noise in the decoherence of a single spin in diamond
P. Jamonneau, M. Lesik, J. P. Tetienne +12
We analyze the impact of electric field and magnetic field fluctuations in the decoherence of the electronic spin associated with a single nitrogen-vacancy (NV) defect in diamond b…
An efficient scheme for sampling fast dynamics at a low average data acquisition rate
A. Philippe, S. Aime, V. Roger +4
We introduce a temporal scheme for data sampling, based on a variable delay between two successive data acquisitions. The scheme is designed so as to reduce the average data flow r…
Local Magnetic Field Role in Star Formation
Patrick M. Koch, Ya-Wen Tang, Paul T. P. Ho +14
We highlight distinct and systematic observational features of magnetic field morphologies in polarized submm dust continuum. We illustrate this with specific examples and show sta…
Completeness of Randomized Kinodynamic Planners with State-based Steering
Stéphane Caron, Quang-Cuong Pham, Yoshihiko Nakamura
Probabilistic completeness is an important property in motion planning. Although it has been established with clear assumptions for geometric planners, the panorama of completeness…
Self-organized magnetic particles to tune the mechanical behaviour of a granular system
Meredith Cox, Dong Wang, Jonathan Barés +1
Above a certain density a granular material jams. This property can be controlled by either tuning a global property, such as the packing fraction or by applying shear strain, or a…
Bursting of Dilute Emulsion-Based Liquid Sheets Driven by a Marangoni Effect
Clara Vernay, Laurence Ramos, Christian Ligoure
We study the destabilization mechanism of thin liquid sheets expanding in air and show that dilute oil-in-water emulsion-based sheets disintegrate through the nucleation and growth…
Equilibrium sampling of hard spheres up to the jamming density and beyond
Ludovic Berthier, Daniele Coslovich, Andrea Ninarello +1
We implement and optimize a particle-swap Monte-Carlo algorithm that allows us to thermalize a polydisperse system of hard spheres up to unprecedentedly-large volume fractions, whe…
The Multilayer Nature of Ecological Networks
Shai Pilosof, Mason A. Porter, Mercedes Pascual +1
Although networks provide a powerful approach to study a large variety of ecological systems, their formulation does not typically account for multiple interaction types, interacti…
Growing timescales and lengthscales characterizing vibrations of amorphous solids
Ludovic Berthier, Patrick Charbonneau, Yuliang Jin +3
Low-temperature properties of crystalline solids can be understood using harmonic perturbations around a perfect lattice, as in Debye's theory. Low-temperature properties of amorph…
Point-to-set lengths, local structure, and glassiness
Sho Yaida, Ludovic Berthier, Patrick Charbonneau +1
The growing sluggishness of glass-forming liquids is thought to be accompanied by growing structural order. The nature of such order, however, remains hotly debated. A decade ago,…
Theta series, wall-crossing and quantum dilogarithm identities
Sergei Alexandrov, Boris Pioline
Motivated by mathematical structures which arise in string vacua and gauge theories with N=2 supersymmetry, we study the properties of certain generalized theta series which appear…
