Magnetocaloric effect in two-dimensional spin-1/2 antiferromagnets
A. Honecker, S. Wessel
The magnetocaloric effect is studied at the transition to saturation in the antiferromagnetic spin-1/2 Heisenberg model on the simplest two-dimensional lattices, namely the square…

A New Approach for Boundary Recognition in Geometric Sensor Networks
Sandor P. Fekete, Michael Kaufmann, Alexander Kroeller +1
We describe a new approach for dealing with the following central problem in the self-organization of a geometric sensor network: Given a polygonal region R, and a large, dense set…
