Point Splitting and U(1) Gauge Invariance
Dirk Olivie
A gauge transformation in quantum electrodynamics involves the product of field operators at the same space-time point and hence does not have a well-defined meaning. One way to av…
Mutual information and self-control of a fully-connected low-activity neural network
D. Bolle', D. Dominguez Carreta
A self-control mechanism for the dynamics of a three-state fully-connected neural network is studied through the introduction of a time-dependent threshold. The self-adapting thres…
Superconductivity with angular dependent coupling: stripes, Coulomb repulsion and enhanced Tc
V. V. Moshchalkov, V. A. Ivanov
We have analysed the effect of intrinsic doping inhomogeneity and the presence of stripes in high-T_c superconductors on coupling λby using a simple analytically solvable model wit…
Numerical Model for Calculating the Field Dependence of the Irreversible Magnetisation of Hard Ssuperconductors in High Pulsed Magnetic Fields
J. Vanacken, L. Trappeniers, K. Rosseel +1
In type II hard superconductors the irreversible magnetization shows an impressive variety of different magnetic field dependencies. In this paper we will try to describe the M(H)…
Parallel dynamics of the asymmetric extremely diluted Ashkin-Teller neural network
D. Bolle', G. Jongen
The parallel dynamics of the asymmetric extremely diluted Ashkin-Teller neural network is studied using signal-to-noise analysis techniques. Evolution equations for the order param…
Comparison of the Transport Mechanism in Underdoped High Temperature Superconductors and in Spin Ladders
J. Vanacken, L. Trappeniers, G. Teniers +6
Recently, the normal state resistivity of high temperature superconductors (in particular in La2-xSrxCuO4 single crystals) has been studied extensively in the region below Tc by su…
Flux Jumps Driven by a Pulsed Magnetic Field
J. Vanacken, L. Trappeniers, K. Rosseel +3
The understanding of flux jumps in the high temperature superconductors is of importance since the occurrence of these jumps may limit the perspectives of the practical use of thes…
Magnetic properties of submicron Co islands and their use as artificial pinning centers
M. J. Van Bael, K. Temst, V. V. Moshchalkov +1
We report on the magnetic properties of elongated submicron magnetic islands and their influence on a superconducting film. The magnetic properties were studied by magnetization hy…
Flux pinning by regular arrays of ferromagnetic dots
M. J. Van Bael, L. Van Look, K. Temst +6
The pinning of flux lines by two different types of regular arrays of submicron magnetic dots is studied in superconducting Pb films; rectangular Co dots with in-plane magnetizatio…
Nucleation of Superconductivity in a Mesoscopic Loop of Finite Width
V. Bruyndoncx, L. Van Look, V. V. Moshchalkov
The normal/superconducting phase boundary Tc has been calculated for mesoscopic loops, as a function of an applied perpendicular magnetic field H. While for thin-wire loops and fil…
Flux pinning in a superconducting film by a regular array of magnetic dots
L. Van Look, M. J. Van Bael, K. Temst +4
We have studied flux pinning in thin superconducting Pb films covering a triangular array of submicron magnetic Au/Co/Au dots with in-plane magnetization. The rectangular dots can…
Two-point functions of chiral operators in {\cal N}=4 SYM at order g^4
S. Penati, A. Santambrogio, D. Zanon
We compute two-point functions of chiral operators Tr Φ^3 in {\cal N}=4 SU(N) supersymmetric Yang-Mills theory to the order g^4 in perturbation theory. We perform explicit calculat…
Quantisation and Gauge Invariance
Jan Govaerts
Recent developments concerning canonical quantisation and gauge invariant quantum mechanical systems and quantum field theories are briefly discussed. On the one hand, it is shown…
Definable sets, motives and p-adic integrals
J. Denef, F. Loeser
We associate canonical virtual motives to definable sets over a field of characteristic zero. We use this construction to show that very general p-adic integrals are canonically in…
2.4 - 197 micron spectroscopy of OH/IR stars: The IR characteristics of circumstellar dust in O-rich environments
R. J. Sylvester, F. Kemper, M. J. Barlow +4
Infrared spectra of a number of evolved O-rich stars have been obtained with the Short- and Long- Wavelength spectrometers on board the Infrared Space Observatory. The very broad w…
A homogeneous study of the s-process in the 21mic carbon-rich post-AGB objects
H. Van Winckel, M. Reyniers
We present in this paper a homogeneous photospheric abundance study, on the basis of the analysis of high resolution optical spectra, of six post-AGB objects displaying a 21mic cir…

L. Trappeniers, J. Vanacken, P. Wagner +7
The normal state resistivity of high temperature superconductors can be probed in the region below Tc by suppressing the superconducting state in high magnetic fields. Here we pres…
An action for the (2,0) self-dual tensor multiplet in a conformal supergravity background
Kor Van Hoof
We present the action for a self-dual tensor in six dimensions, coupled to a (2,0) conformal supergravity background. This action gives rise to the expected equations of motion. An…
