Melting transitions of fluxline arrays — •Roland Schorr and Ludger Santen — Universität des Saarlandes, FR7.1 Theoretische Physik, Postfach 151150, 66041 Saarbrücken

We investigate the “melting transition” of fluxline arrays. The fluxlines are modeled as interacting elastic lines on two and three dimensional lattices. The model under consideration can be mapped on the six vertex model, which allows for very efficient simulations by using cluster MC algorithms, i.e. we obtain a vanishing dynamical exponent for the pure case. One observes two kinds of melting transitions either driven by the disorder or the temperature. In the pure case we observe a continuous melting of the fluxline lattice.
