The nature of turbulence in OMC1 at the star forming scale: observations and simulations
M. Gustafsson, A. Brandenburg, J. L. Lemaire +1
Aim: To study turbulence in the Orion Molecular Cloud (OMC1) by comparing observed and simulated characteristics of the gas motions. Method: Using a dataset of vibrationally excite…
Classification of the solutions of constant rational semi-dynamical reflection equations
Jean Avan, Genevieve Rollet
We propose a classification of the solutions K to the semi-dynamical reflection equation with constant rational structure matrices associated to rational scalar Ruijsenaars-Schneid…
Integration over compact quantum groups
Teodor Banica, Benoit Collins
We find a combinatorial formula for the Haar functional of the orthogonal and unitary quantum groups. As an application, we consider diagonal coefficients of the fundamental repres…
Persistent currents in two dimensions: New regimes induced by the interplay between electronic correlations and disorder
Zoltan Adam Nemeth, Jean-Louis Pichard
Using the persistent current I induced by an Aharonov-Bohm flux in square lattices with random potentials, we study the interplay between electronic correlations and disorder upon…
Wavelets, ridgelets and curvelets on the sphere
Jean-Luc Starck, Yassir Moudden, Pierrick Abrial +1
We present in this paper new multiscale transforms on the sphere, namely the isotropic undecimated wavelet transform, the pyramidal wavelet transform, the ridgelet transform and th…
Probing Turbulence with Infrared Observations in OMC1
M. Gustafsson, D. Field, J. L. Lemaire +1
A statistical analysis is presented of the turbulent velocity structure in the Orion Molecular Cloud at scales ranging from 70 AU to 30000 AU. Results are based on IR Fabry-Perot i…
Exact results for the sigma^z two-point function of the XXZ chain at Delta=1/2
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
We propose a new multiple integral representation for the correlation function <sigma_1^z sigma_{m+1}^z> of the XXZ spin-1/2 Heisenberg chain in the disordered regime. We show that…
Localizations at infinity and essential spectrum of quantum Hamiltonians: I. General theory
Vladimir Georgescu, Andrei Iftimovici
We isolate a large class of self-adjoint operators H whose essential spectrum is determined by their behavior at large x and we give a canonical representation of their essential s…
Quantum effective potential, electron transport and conformons in biopolymers
Rossen Dandoloff, Radha Balakrishnan
In the Kirchhoff model of a biopolymer, conformation dynamics can be described in terms of solitary waves, for certain special cross-section asymmetries. Applying this to the probl…
A necklace of Wulff shapes
Joël De Coninck, François Dunlop, Thierry Huillet
In a probabilistic model of a film over a disordered substrate, Monte-Carlo simulations show that the film hangs from peaks of the substrate. The film profile is well approximated…
Confinement and Superfluidity in one-dimensional Degenerate Fermionic Cold Atoms
P. Lecheminant, E. Boulat, P. Azaria
The physical properties of arbitrary half-integer spins fermionic cold atoms trapped in a one-dimensional optical lattice are investigated by means of a low-energy ap…
Fast Flat-Histogram Method for Generalized Spin Models
Sylvain Reynal, Hung-The Diep
We present a Monte Carlo method that efficiently computes the density of states for spin models having any number of interaction per spin. By combining a random-walk in the energy…
Quantum walks on Cayley graphs
O. Lopez Acevedo, T. Gobron
We address the problem of the construction of quantum walks on Cayley graphs. Our main motivation is the relationship between quantum algorithms and quantum walks. In particular, w…
New characterizations of the region of complete localization for random Schrödinger operators
Francois Germinet, Abel Klein
We study the region of complete localization in a class of random operators which includes random Schrödinger operators with Anderson-type potentials and classical wave operators i…
The electronic structure of LaSrMnO thin films and its dependence as studied by angle-resolved photoemission
M. Shi, M. C. Falub, P. R. Willmott +6
We present angle-resolved photoemission spectroscopy results for thin films of the three-dimensional manganese perovskite LaSrMnO. We show that the transition t…
Dynamics of point Josephson junctions in a microstrip line
J. G. Caputo, L. Loukitch
We model the dynamics of point Josephson junctions in a 1D microstrip line using a wave equation with delta distributed sine nonlinearities. The model is suitable for both low T$_c…
Spin chains from dynamical quadratic algebras
Zoltan Nagy, Jean Avan
We present a construction of integrable quantum spin chains where local spin-spin interactions are weighted by ``position''-dependent potential containing abelian non-local spin de…
Foams in contact with solid boundaries: equilibrium conditions and conformal invariance
M. Mancini, C. Oguey
A liquid foam in contact with a solid surface forms a two-dimensional foam on the surface. We derive the equilibrium equations for this 2D foam when the solid surface is curved and…
