Disorder-induced phases in the S=1 antiferromagnetic Heisenberg chain
Péter Lajkó, Enrico Carlon, Heiko Rieger +1
We use extensive density matrix renormalization group (DMRG) calculations to explore the phase diagram of the random S=1 antiferromagnetic Heisenberg chain with a power-law distrib…
Elastic lines on splayed columnar defects studied numerically
Viljo Petaja, Matti Sarjala, Mikko Alava +1
We investigate by exact optimization method properties of two- and three-dimensional systems of elastic lines in presence of splayed columnar disorder. The ground state of many lin…
Maximum flow and topological structure of complex networks
Deok-Sun Lee, Heiko Rieger
The problem of sending the maximum amount of flow between two arbitrary nodes and of complex networks along links with unit capacity is studied, which is equivalent to…
Aging and scaling laws in -hydroquinone-clathrate
Maikel C. Rheinstädter, Heiko Rieger, Klaus Knorr
The dielectric permittivity of the orientational glass methanol(x=0.73)--hydroquinone-clathrate has been studied as function of temperature and waiting time using different temp…
Constrained spin dynamics description of random walks on hierarchical scale-free networks
Jae Dong Noh, Heiko Rieger
We study a random walk problem on the hierarchical network which is a scale-free network grown deterministically. The random walk problem is mapped onto a dynamical Ising spin chai…
Random Walks on Complex Networks
Jae Dong Noh, Heiko Rieger
We investigate random walks on complex networks and derive an exact expression for the mean first passage time (MFPT) between two nodes. We introduce for each node the random walk…
