Discrete stochastic models for traffic flow
M. Schreckenberg, A. Schadschneider, K. Nagel +1
We investigate a probabilistic cellular automaton model which has been introduced recently. This model describes single-lane traffic flow on a ring and generalizes the asymmetric e…
Superconductivity in an exactly solvable Hubbard model with bond-charge interaction
Andreas Schadschneider
The Hubbard model with an additional bond-charge interaction is solved exactly in one dimension for the case where is the hopping amplitude. In this case the number o…
model as effective Hamiltonian for generalized Hubbard models with broken -symmetry
G. Albertini, V. E. Korepin, A. Schadschneider
We consider the limit of strong Coulomb attraction for generalized Hubbard models with -symmetry. In this limit these models are equivalent to the ferromagnetic spin-1/2 Heisenb…
-pairing as a mechanism of superconductivity in models of strongly correlated electrons
Jan de Boer, Vladimir E. Korepin, Andreas Schadschneider
We consider extended versions of the Hubbard model which contain additional interactions between nearest neighbours. In this letter we show that a large class of these models has a…
Reentrant Behavior in the Domany-Kinzel Cellular Automaton
H. Rieger, A. Schadschneider, M. Schreckenberg
We present numerical and analytical results for a special kind of one-dimensional probabilistic cellular automaton, the so called Domany-Kinzel automaton. It is shown that the phas…
