Amplified short-wavelength light scattered by relativistic electrons in the laser-induced optical lattice
I. A. Andriyash, V. T. Tikhonchuk, V. Malka +2
The scheme of the XUV/X-ray free electron laser based on the optical undulator created by two overlapped transverse laser beams is analyzed. A kinetic theoretical description and a…
Modeling Complex Organic Molecules in dense regions: Eley-Rideal and complex induced reaction
M. Ruaud, J. C. Loison, K. M. Hickson +3
Recent observations have revealed the existence of Complex Organic Molecules (COMs) in cold dense cores and prestellar cores. The presence of these molecules in such cold condition…
Boosting terahertz generation in laser-field ionized gases using a sawtooth wave shape
P. González de Alaiza Martínez, I. Babushkin, L. Bergé +6
Broadband ultrashort terahertz (THz) pulses can be produced using plasma generation in a noble gas ionized by femtosecond two-color pulses. Here we demonstrate that, by using multi…
Observations of water with Herschel/HIFI toward the high-mass protostar AFGL 2591
Y. Choi, F. F. S. van der Tak, E. F. van Dishoeck +2
Water is a sensitive tracer of physical conditions in star-forming regions because of its large abundance variations between hot and cold regions. We use spectrally resolved observ…
The Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO)
R. Carrera, L. Casamiquela, L. Balaguer-Núñez +10
We present the motivation, design and current status of the Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO). Using the high resolution spectroscopic fac…
Growth of CaMnO Ruddlesden-Popper structured thin films using Combinatorial Substrate Epitaxy
M. Lacotte, A. David, D. Pravarthana +6
The local epitaxial growth of pulsed laser deposited CaMnO films on polycrystalline spark plasma sintered SrTiO substrates was investigated to determine phase forma…
On algebraic surfaces of general type with negative c2
Yi Gu
We prove that for any prime number , there exists a positive number such that holds true for all algebraic surfaces of general type…
Teegi: Tangible EEG Interface
Jérémy Frey, Renaud Gervais, Stéphanie Fleck +2
We introduce Teegi, a Tangible ElectroEncephaloGraphy (EEG) Interface that enables novice users to get to know more about something as complex as brain signals, in an easy, en- gag…
Heart Rate Monitoring as an Easy Way to Increase Engagement in Human-Agent Interaction
Jérémy Frey
Physiological sensors are gaining the attention of manufacturers and users. As denoted by devices such as smartwatches or the newly released Kinect 2 -- which can covertly measure…
Influence of different parameters on the chemical composition of warm neptunes
Olivia Venot, Marcelino Agúndez, Franck Selsis +2
We developed a 1D photo-thermochemical model to study the atmosphere of warm exoplanets. The chemical scheme used in this model is completely new in planetology and has been constr…
Approach to asymptotically diffusive behavior for Brownian particles in media with periodic diffusivities
David S. Dean, Thomas Guérin
We analyze the mean squared displacement of a Brownian particle in a medium with a spatially varying local diffusivity which is assumed to be periodic. When the system is asymptoti…
A simple Cartesian scheme for compressible multimaterials
Yannick Gorsse, Angelo Iollo, Thomas Milcent +1
We present a simple numerical method to simulate the interaction of two non-miscible compressible materials separated by an interface. The media considered may have significantly d…
Coherent view of crystal chemistry and ab initio analyses of Pb(II) and Bi(III) Lone Pair in square planar coordination
Samir F. Matar, Jean Galy
The stereochemistry of 6s2 (E) lone pair of divalent Pb and trivalent Bi (PbII and BiIII designated by M*) in structurally related PbO, PbFX (X= Cl, Br, I), BiOX (X= F, Cl, Br, I)…
Equations over free inverse monoids with idempotent variables
Volker Diekert, Florent Martin, Geraud Senizergues +1
We introduce the notion of idempotent variables for studying equations in inverse monoids. It is proved that it is decidable in singly exponential time (DEXPTIME) whether a system…
Minkowski Sum of Polytopes Defined by Their Vertices
Vincent Delos, Denis Teissandier
Minkowski sums are of theoretical interest and have applications in fields related to industrial backgrounds. In this paper we focus on the specific case of summing polytopes as we…
New N-bearing species towards OH231.8+4.2: HNCO, HNCS, HCN and NO
L. Velilla Prieto, C. Sánchez Contreras, J. Cernicharo +7
OH231.8+4.2 is a well studied O-rich CSE around an intermediate-mass evolved star that displays bipolar molecular outflows accelerated up to 400 km/s. OH231 also presents an except…
Qubit-Programmable Operations on Quantum Light Fields
Marco Barbieri, Nicolò Spagnolo, Franck Ferreyrol +3
Engineering quantum operations is one of the main abilities we need for developing quantum technologies and designing new fundamental tests. Here we propose a scheme for realising…
The Sagnac effect: 20 years of development in matter-wave interferometry
Brynle Barrett, Remi Geiger, Indranil Dutta +5
Since the first atom interferometry experiments in 1991, measurements of rotation through the Sagnac effect in open-area atom interferometers has been studied. These studies have d…
ALMA Observations of Anisotropic Dust Mass-loss in the Inner Circumstellar Environment of the Red Supergiant VY Canis Majoris
