Novel pinning phenomena in a superconducting film with a square lattice of artificial pinning centers
Z. Jiang, D. A. Dikin, V. V. Metlushko +2
We study the transport properties of a superconducting Nb film with a square lattice of artificial pinning centers (APCs) as a function of dc current, at a temperature close to the…
A study of the s-process in the carbon-rich post-AGB stars IRAS06530-0213 and IRAS08143-4406 on the basis of VLT-UVES spectra
Maarten Reyniers, Hans Van Winckel, Roberto Gallino +1
In an effort to extend the still limited sample of s-process enriched post-AGB stars, high-resolution, high signal-to-noise VLT+UVES spectra of the optical counterparts of the infr…
Anisotropic scaling in YBa2Cu3O7 crystals with columnar defects
Alejandro V. Silhanek, Leonardo Civale
We explore the interplay between the mass anisotropy and the uniaxial pinning of tilted columnar defects (CD) in a YBa2Cu3O7 single crystal. At high temperatures T and fields H a s…
The Potts model built on sand
E. Dinaburg, C. Maes, S. Pirogov +2
We consider the q=4 Potts model on the square lattice with an additional hard-core nonlocal interaction. That interaction arises from the choice of the reference measure taken to b…
Quark Mixing, CKM Unitarity
H. Abele, E. Barberio, D. Dubbers +5
In the Standard Model of elementary particles, quark-mixing is expressed in terms of a 3 x 3 unitary matrix V, the so called Cabibbo-Kobayashi-Maskawa (CKM) matrix. Significant uni…
Influence of the stray field of magnetic dot on the nucleation of superconductivity in a disk
D. S. Golubovic, W. V. Pogosov, M. Morelle +1
We have investigated the nucleation of superconductivity in an Al mesoscopic disk, with a magnetic dot on the top. The dot is magnetized perpendicularly, and its magnetic field is…
Continuity of quantum conditional information
R. Alicki, M. Fannes
We prove continuity of quantum conditional information with respect to the uniform convergence of states and obtain a bound which is independent of the dimension o…
The gap-tooth scheme for homogenization problems
Giovanni Samaey, Dirk Roose, Ioannis G. Kevrekidis
An important class of problems exhibits smooth behaviour in space and time on a macroscopic scale, while only a microscopic evolution law is known. For such time-dependent multi-sc…
The gauge invariance of the non-Abelian Chern-Simons action for D-branes revisited
Joke Adam, Jos Gheerardyn, Bert Janssen +1
We present an elegant method to prove the invariance of the Chern-Simons part of the non-Abelian action for N coinciding D-branes under the R-R and NS-NS gauge transformations, by…
Cellular automaton for bacterial towers
J. O. Indekeu, C. V. Giuraniuc
A simulation approach to the stochastic growth of bacterial towers is presented, in which a non-uniform and finite nutrient supply essentially determines the emerging structure thr…
Evidence for grain growth in T Tauri disks
F. Przygodda, R. van Boekel, P. Àbrahàm +3
In this article we present the results from mid-infrared spectroscopy of a sample of 14 T Tauri stars with silicate emission. The qualitative analysis of the spectra reveals a corr…
Phase diagram of a superconductor / ferromagnet bilayer
M. Lange, M. J. Van Bael, V. V. Moshchalkov
The magnetic field (H) - temperature (T) phase diagram of a superconductor is significantly altered when domains are present in an underlying ferromagnet with perpendicular magneti…
A microscopic model for Josephson currents
J. Lauwers, A. Verbeure
A microscopic model of a Josephson junction between two superconducting plates is proposed and analysed. For this model, the nonequilibrium steady state of the total system is expl…
Enhancing a Search Algorithm to Perform Intelligent Backtracking
Maurice Bruynooghe
This paper illustrates how a Prolog program, using chronological backtracking to find a solution in some search space, can be enhanced to perform intelligent backtracking. The enha…
Polyvector Super-Poincare Algebras
Dmitri V. Alekseevsky, Vicente Cortés, Chandrashekar Devchand +1
A class of Z_2-graded Lie algebra and Lie superalgebra extensions of the pseudo-orthogonal algebra of a spacetime of arbitrary dimension and signature is investigated. They have th…
Special Attention Network
J. O. Indekeu
In this Note a social network model for opinion formation is proposed in which a person connected to partners pays an {\em attention} to each partner. The mutual attentio…
Central limit theorems for the large-spin asymptotics of quantum spins
Tom Michoel, Bruno Nachtergaele
We use a generalized form of Dyson's spin wave formalism to prove several central limit theorems for the large-spin asymptotics of quantum spins in a coherent state.
Direct measurement of the size and shape of the present-day stellar wind of Eta Carinae
R. van Boekel, P. Kervella, M. Schoeller +7
We present new high angular resolution observations at near-IR wavelengths of the core of the Luminous Blue Variable Eta Carinae, using NAOS-CONICA at the VLT and VINCI at the VLT…
Little-Parks effect in a superconducting loop with magnetic dot
D. S. Golubovic, W. V. Pogosov, M. Morelle +1
We have studied the nucleation of superconductivity in a mesoscopic Al loop, enclosing magnetic dot with perpendicular magnetization. The superconducting phase boundary Tc(B), dete…
The Role of Nonlocality in the Pinning Properties of Borocarbides Materials
A. V. Silhanek, J. R. Thompson, L. Civale +2
An experimental review on the influence of nonlocal electrodynamics in the vortex pinning properties of non-magnetic borocarbide superconductors is presented. We show that the pinn…
The peculiar circumstellar environment of NGC2024-IRS2
A. Lenorzer, A. Bik, A. de Koter +5
We re-examine the nature of NGC2024-IRS2 in light of the recent discovery of the late O-type star, IRS2b, located 5 arcsec from IRS2. Using L-band spectroscopy, we set a lower limi…
Determining the Metallicity of Cepheid Stars in the SMC, LMC and the Galaxy
M. Mottini, F. Primas, M. Romaniello +1
The Cepheid Period-Luminosity relation is unquestionably one of the most powerful tools at our disposal for determining the extragalactic distance scale. While significant progress…
Damping factors for the gap-tooth scheme
Giovanni Samaey, Ioannis G. Kevrekidis, Dirk Roose
An important class of problems exhibits macroscopically smooth behaviour in space and time, while only a microscopic evolution law is known. For such time-dependent multi-scale pro…
A Generalisation of (Very) Special Geometry
Jos Gheerardyn
We construct non-Abelian N=2 on-shell vector multiplets in five and in four dimensions. Closing of the supersymmetry algebra imposes dynamical constraints on the fields, and these…
