Chirality and $Z_2$ vortices in an Heisenberg spin model on the kagom\'e lattice (2007)
Lhuillier, C., Messio, L., Pierre, L., Viot, P.
The phase diagram of the classical \jj model on the \kag lattice is investigated using extensive \mc simulations. In a realistic range of parameters, this model has a low-temperature chiral-ordered...
The X-HPD: Development of a large spherical hybrid photodetector (2007)
Braem, André, Joram, C, Séguinot, Jacques, Pierre, L, Lavoute, P
The X-HPD concept is a modern implementation of the Dumand and Lake Baikal approach to large area photon detectors, primarily aimed at water based Cherenkov detectors. Our prototype detector consists...
Misguich, G., Bernu, B., Pierre, L.
We present a high-temperature expansion (HTE) of the magnetic susceptibility and specific heat data of Melzi et al. on Li2VOSiO4 [Phys. Rev. B 64, 024409 (2001)]. The data are very well reproduced by...
A compositional model for the functional verification of high-level synthesis results (2000)
Borrione, D., Dushina, J., Pierre, L.
High-level synthesis systems, such as Amical, translate a behavioral description to an abstract automaton in which the states are decision and synchronization points, and operations are executed on...
First excitations of the spin 1/2 Heisenberg antiferromagnet on the kagom\'e lattice (1998)
Waldtmann, Ch., Bernu, B., Sindzingre, P., Lhuillier, C., Lecheminant, P., ...
We study the exact low energy spectra of the spin 1/2 Heisenberg antiferromagnet on small samples of the kagom\'e lattice of up to N=36 sites. In agreement with the conclusions of previous authors,...
Borrione, D., Dushina, J., Pierre, L.
This research aims at verifying the abstract specification levels of standard hardware description languages (we use VHDL [IE931). HLS translates a behavioral description, written as one or more...
Lecheminant, P., Bernu, B., Lhuillier, C., Pierre, L., Sindzingre, P.
A group symmetry analysis of the low lying levels of the spin-1/2 kagom\'e Heisenberg antiferromagnet is performed for small samples up to N=27. This approach allows to follow the effect of quantum...
Lecheminant, P., Bernu, B., Lhuillier, C., Pierre, L.
On the triangular lattice, for $J_2/J_1$ between $1/8$ and $1$, the classical Heisenberg model with first and second neighbor interactions presents four-sublattice ordered ground-states. Spin-wave...
Bernu, B., Lecheminant, P., Lhuillier, C., Pierre, L.
Exact spectra of periodic samples are computed up to $ N=36 $. Evidence of an extensive set of low lying levels, lower than the softest magnons, is exhibited. These low lying quantum states are...
Calcul et mesure de la température d'un plasma à l'aide des raies d'émission du cuivre (1994)
Sassi, M., Pierre, L., Bénard, J., Cahen, C.
L'utilisation des raies d'émission du cuivre pour la mesure de la température dans les plasmas est présentée. Cet article expose les problèmes posés par l'étude des températures dans les...

PREVAIL: a proof environment for VHDL descriptions (1992)
Borrione, D., Pierre, L., Salem, A.
The authors describe a formal verification environment for proving the equivalence of two VHDL architectures of the same design entity, provided the designer conforms to some restrictions in the...
Functional modelling and testing of digital circuits (1989)
Borrione, D., Pierre, L., Collavizza, H.
The approach suggested by a team engaged in augmentation of simulated circuit validation by automatic testing is explained with reference to a functional model and three automatic demonstration...
Characterization of endothelin receptors in rat renal artery in vitro.
1. The aim of this study was to investigate the function and characteristics of endothelin receptors in rat main branch renal artery in vitro. 2. Endothelin(ET)-1 (mean EC50 = 9.8 nM) was...
