Genetic embedded matching approach to ground states in continuous-spin systems
Martin Weigel
Due to an extremely rugged structure of the free energy landscape, the determination of spin-glass ground states is among the hardest known optimization problems, found to be NP-ha…
Zero-temperature phase of the XY spin glass in two dimensions: Genetic embedded matching heuristic
Martin Weigel, Michel J. P. Gingras
For many real spin-glass materials, the Edwards-Anderson model with continuous-symmetry spins is more realistic than the rather better understood Ising variant. In principle, the n…
Self-affirmation model for football goal distributions
Elmar Bittner, Andreas Nussbaumer, Wolfhard Janke +1
Analyzing football score data with statistical techniques, we investigate how the highly co-operative nature of the game is reflected in averaged properties such as the distributio…
Frustration effects in antiferromagnets on planar random graphs
Martin Weigel, Des Johnston
We consider the effect of geometric frustration induced by the random distribution of loop lengths in the "fat" graphs of the dynamical triangulations model on coupled antiferromag…
