Fisher's scaling relation above the upper critical dimension
R. Kenna, B. Berche
Fisher's fluctuation-response relation is one of four famous scaling formulae and is consistent with a vanishing correlation-function anomalous dimension above the upper critical d…
Kinetic pathways to the magnetic charge crystal in artificial dipolar spin ice
I. A. Chioar, B. Canals, D. Lacour +6
We investigate experimentally magnetic frustration effects in thermally active artificial kagome spin ice. Starting from a paramagnetic state, the system is cooled down below the C…
On the control by electromagnetic fields of quantum systems with infinite dimensional Hilbert space
Elie Assémat, Thomas Chambrion, Dominique Sugny
We analyze the control by electromagnetic fields of quantum systems with infinite dimensional Hilbert space and a discrete spectrum. Based on recent mathematical results, we rigoro…
Belief revision in the propositional closure of a qualitative algebra
Valmi Dufour-Lussier, Alice Hermann, Florence Le Ber +1
Belief revision is an operation that aims at modifying old be-liefs so that they become consistent with new ones. The issue of belief revision has been studied in various formalism…
Construction of normal numbers via pseudo-polynomial prime sequences
Manfred G. Madritsch
In the present paper we construct normal numbers in base by concatenating -ary expansions of pseudo polynomials evaluated at the primes. This extends a recent result by Tich…
Seebeck Nanoantennas for Infrared Detection and Energy Harvesting Applications
Edgar Briones, Joel Briones, J. C. Martinez-Anton +6
In this letter we introduce a new type of infrared sensor, based on thermocouple nanoantennas, which enables the energy detection and gathering in the mid-infrared region. The prop…
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…
Predicting results of the Research Excellence Framework using departmental -Index
Olesya Mryglod, Ralph Kenna, Yurij Holovatch +1
We compare estimates for past institutional research performances coming from two bibliometric indicators to the results of the UK's Research Assessment Exercise which last took pl…
Classical Noether's theory with application to the linearly damped particle
Raphaël Leone, Thierry Gourieux
This paper provides a modern presentation of Noether's theory in the realm of classical dynamics, with application to the problem of a particle submitted to both a potential and a…
Iwahori-Hecke algebras for Kac-Moody groups over local fields
Nicole Bardy-Panse, Stéphane Gaussent, Guy Rousseau
We define the Iwahori-Hecke algebra for an almost split Kac-Moody group over a local non-archimedean field. We use the hovel associated to this situation, which is the analogue of…
Forms of differing degrees over number fields
Christopher Frei, Manfred Madritsch
Consider a system of polynomials in many variables over the ring of integers of a number field . We prove an asymptotic formula for the number of integral zeros of this system i…
Fluctuations of the heat exchanged between two quantum spin chains
Gabriel T. Landi, Dragi Karevski
The statistics of the heat exchanged between two quantum XX spin chains prepared at different temperatures is studied within the assumption of weak coupling. This provides simple f…
Rational extensions of the trigonometric Darboux-Pöschl-Teller potential based on para-Jacobi polynomials
B. Bagchi, Y. Grandati, C. Quesne
The possibility for the Jacobi equation to admit in some cases general solutions that are polynomials has been recently highlighted by Calogero and Yi, who termed them para-Jacobi…
Formal Semantic Annotations for Models Interoperability in a PLM environment
Y. Liao, M. Lezoche, H. Panetto +2
Nowadays, the need for system interoperability in or across enterprises has become more and more ubiquitous. Lots of research works have been carried out in the information exchang…
Existence and unicity of co-moments in multisymplectic geometry
Leonid Ryvkin, Tilmann Wurzbacher
Given a multisymplectic manifold and a Lie algebra acting on it by infinitesimal symmetries, Fregier-Rogers-Zambon define a homotopy (co-)moment as an $L_{\infty…
Exhausting families of representations and spectra of pseudodifferential operators
Victor Nistor, Nicolas Prudhon
Families of representations of suitable Banach algebras provide a powerful tool in the study of the spectral theory of (pseudo)differential operators and of their Fredholmness. We…
Twisted geometric Satake equivalence: reductive case
Sergey Lysenko
In this paper we extend the twisted Satake equivalence established in arXiv:0809.3738 for almost simple groups to the case of split reductive groups.
Almost algebraic actions of algebraic groups and applications to algebraic representations
Uri Bader, Bruno Duchesne, Jean Lécureux
Let G be an algebraic group over a complete separable valued field k. We discuss the dynamics of the G-action on spaces of probability measures on algebraic G-varieties. We show th…
Monte Carlo methods for linear and non-linear Poisson-Boltzmann equation
Mireille Bossy, Nicolas Champagnat, Helene Leman +3
The electrostatic potential in the neighborhood of a biomolecule can be computed thanks to the non-linear divergence-form elliptic Poisson-Boltzmann PDE. Dedicated Monte-Carlo meth…
New Experimental Method for Investigating AC-losses in Concentric HTS Power Cables
Steffen Elschner, Eduard Demencik, Bruno Douine +6
The optimization of a HTS cable design with respect to AC-losses is of crucial importance for the economic viability of the respective concept. However the experimental determinati…
Pressure tensor in the presence of velocity shear: stationary solutions and self-consistent equilibria
S. S. Cerri, F. Pegoraro, F. Califano +2
Observations and numerical simulations of laboratory and space plasmas in almost collisionless regimes reveal anisotropic and non-gyrotropic particle distribution functions. We inv…
A metric characterisation of repulsive tilings
J. Savinien
A tiling of is repulsive if no -patch can repeat arbitrarily close to itself, relative to . This is a characteristic property of aperiodic order, for a non rep…
On the Hardy-Schrödinger operator with a boundary singularity
Nassif Ghoussoub, Frédéric Robert
We investigate the Hardy-Schrödinger operator on domains $Ω\subset\rn$, whose boundary contain the singularity . The situation is quite different from the…
Amenable Invariant Random Subgroups
Uri Bader, Bruno Duchesne, Jean Lecureux
We show that an amenable Invariant Random Subgroup of a locally compact second countable group lives in the amenable radical. This answers a question raised in the introduction of…
