Dynamics of the Wang-Landau algorithm and complexity of rare events for the three-dimensional bimodal Ising spin glass
S. Alder, S. Trebst, A. K. Hartmann +1
We investigate the performance of flat-histogram methods based on a multicanonical ensemble and the Wang-Landau algorithm for the three-dimensional +/- J spin glass by measuring ro…
Propagation of Ripples in Monte Carlo Models of Sputter Induced Surface Morphology
Emmanuel O. Yewande, Alexander K. Hartmann, Reiner Kree
Periodic ripples generated from the off-normal incidence ion beam bombardment of solid surfaces have been observed to propagate with a dispersion in the velocity. We investigate th…
Clustering analysis of the ground-state structure of the vertex-cover problem
Wolfgang Barthel, Alexander K. Hartmann
Vertex cover is one of the classical NP-complete problems in theoretical computer science. A vertex cover of a graph is a subset of vertices such that for each edge at least one of…
