Graph theory and Pfaffian representations of Ising partition function
Thierry Gobron
A well known theorem due to Kasteleyn states that the partition function of an Ising model on an arbitrary planar graph can be represented as the Pfaffian of a skew-symmetric matri…
Mixing properties of the one-atom maser
Laurent Bruneau
We study the relaxation properties of the quantized electromagnetic field in a cavity under repeated interactions with single two-level atoms, so-called one-atom maser. We improve…
Young stellar object jet models: From theory to synthetic observations
O. Tesileanu, T. Matsakos, S. Massaglia +9
Astronomical observations, analytical solutions and numerical simulations have provided the building blocks to formulate the current theory of young stellar object jets. Although e…
Observation of a quantum Cheshire Cat in a matter wave interferometer experiment
Tobias Denkmayr, Hermann Geppert, Stephan Sponar +4
From its very beginning quantum theory has been revealing extraordinary and counter-intuitive phenomena, such as wave-particle duality, Schrödinger cats and quantum non-locality. I…
Electronic structure and transport in approximants of the Penrose tiling
Guy Trambly de Laissardière, Attila Szállás, Didier Mayou
We present numerical calculations of electronic structure and transport in Penrose approximants. The electronic structure of perfect approximants shows a spiky density of states an…
On the ergodic theory of free group actions by real-analytic circle diffeomorphisms
Bertrand Deroin, Victor Kleptsyn, Andrés Navas
We consider finitely generated groups of real-analytic circle diffeomorphisms. We show that if such a group admits an exceptional minimal set (i.e., a minimal invariant Cantor set)…
Conductivity of Graphene with Resonant Adsorbates: Beyond the Nearest Neighbor Hopping Model
Guy Trambly de Laissardière, Didier Mayou
Adsorbates on graphene can create resonances that lead to efficient electron scattering and strongly affect the electronic conductivity. Therefore a proper description of these res…
Resonant averaging for small solutions of stochastic NLS equations
Sergei Kuksin, Alberto Maiocchi
We consider the free linear Schrödinger equation on a torus , perturbed by a hamiltonian nonlinearity, driven by a random force and damped by a linear damping: $$ u_t…
Threshold Saturation for Nonbinary SC-LDPC Codes on the Binary Erasure Channel
Iryna Andriyanova, Alexandre Graell i Amat
We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) code ensembles defined over the general linear group on the binary erasure c…
On the form factors of local operators in the Bazhanov-Stroganov and chiral Potts models
N. Grosjean, J. M. Maillet, G. Niccoli
We consider general cyclic representations of the 6-vertex Yang-Baxter algebra and analyze the associated quantum integrable systems, the Bazhanov-Stroganov model and the correspon…
Single polymer gating of channels under a solvent gradient
S Nath, D P Foster, D Giri +1
We study the effect of a gradient of solvent quality on the coil-globule transition for a polymer in a narrow pore. A simple self-attracting self-avoiding walk model of a polymer i…
The Hartree equation for infinitely many particles. II. Dispersion and scattering in 2D
Mathieu Lewin, Julien Sabin
We consider the nonlinear Hartree equation for an interacting gas containing infinitely many particles and we investigate the large-time stability of the stationary states of the f…
Remarks on the quantum de Finetti theorem for bosonic systems
Mathieu Lewin, Phan Thành Nam, Nicolas Rougerie
The quantum de Finetti theorem asserts that the k-body density matrices of a N-body bosonic state approach a convex combination of Hartree states (pure tensor powers) when N is lar…
The Hartree equation for infinitely many particles. I. Well-posedness theory
Mathieu Lewin, Julien Sabin
We show local and global well-posedness results for the Hartree equation where is a bounded self-adjoint operator on , …
Silicon Sheets By Redox Assisted Chemical Exfoliation
Mohamed Rachid Tchalala, Mustapha Ait Ali, Hanna Enriquez +15
In this paper, we report the direct chemical synthesis of silicon sheets in gram-scale quantities by chemical exfoliation of pre-processed calcium di-silicide (CaSi2). We have used…
A family of monotone quantum relative entropies
Mathieu Lewin, Julien Sabin
We study here the elementary properties of the relative entropy $\cH(A,B)=\tr[ϕ(A)-ϕ(B)-ϕ'(B)(A-B)]$ for a convex function and bounded self-adjoint operators. In particul…
Thermal stability of standalone silicene sheet
Virgile Bocchetti, Hung T. Diep, H. Enriquez +2
Extensive Monte Carlo simulations are carried out to study thermal stability of an infinite standalone silicon sheet. We used the Tersoff potential that has been used with success…
On the stability of the notion of non-characteristic point and blow-up profile for semilinear wave equations
Frank Merle, Hatem Zaag
We consider a blow-up solution for the semilinear wave equation in dimensions, with subconformal power nonlinearity. Introducing $\RR_0$ the set of non-characteristic points wi…
Anomalous electronic transport in Quasicrystals and related Complex Metallic Alloys
Guy Trambly de Laissardière, Didier Mayou
We analyze the transport properties in approximants of quasicrystals alpha-AlMnSi, 1/1-AlCuFe and for the complex metallic phase lambda-AlMn. These phases presents strong analogies…
Is superhydrophobicity robust with respect to disorder?
Joël De Coninck, François Dunlop, Thierry Huillet
We consider theoretically the Cassie-Baxter and Wenzel states describing the wetting contact angles for rough substrates. More precisely, we consider different types of periodic ge…
