Dynamical Scaling of the Island-Size Distribution and Percolation in Submonolayer Molecular Beam Epi the case of dendritic island growth are presented. The scaling of the island density, monomer density, island-size distribution, structure factor, and pair-correlation function are studied as a function of the coverage θ and the ratio R = D/F of the diffusion rate D to the deposition rate F. Our re

The Density-Matrix Renormalization Group for Fermion Systemsshow numerical results for equal-time spin-spin and singlet pair field correlation functions, as well as the spin gap for the Hubbard model on two chains. The system is a gapped spin liquid at half-filling and shows weak algebraic .-wave-like pair field correlations away from half-filling.

Excitation Spectra in the 1-D Hubbard Model from Quantum-Monte-Carlo Simulationsical expectation values of physical observables. Recent developments however, made possible to perform an analytic continuation of imaginary-time quantum Monte Carlo data into real-frequency spectra. In particular the maximum-entropy method (MEM) was successfully applied to the Anderson impurity mod

The method uses as a key ingredient a trial phase that plays the role of gauge function in the unitary transformation that maps the original fermion problem to a boson problem for the modulus of the wavefunction. In particular, we investigate the ground state of an ideal 2. electron g

Monte Carlo with Absorbing Markov Chains: A Faster Monte-Carlo Algorithm for Dynamical Studieslest form of the MCAMC algorithm corresponds to the .-fold way algorithm. The MCAMC algorithm is applied to the study of the escape from the metastable state of the square-lattice Ising ferromagnet. Results agree with both continuum and discrete droplet theory.

Non-Arrhenius Conductivity in a Driven System of Interacting Lattice Gasvaluated in the steady state although the system is not in thermal equilibrium. Effects of the concentration of the caniers and the temperature are analyzed. The conductivity shows a nonmonotonic dependence on the concentration and a non-Anhenius dependence over a wide range of temperatures.

Non-Equilibrium Steady States of Ising Systems. Unlike equilibrium systems, where the static properties are independent of the dynamics, the behavior of nonequilibrium systems depends crucially on the dynamics. Various NESS Ising models, having both conserved and non-conserved dynamics, are considered. Their phase diagrams and the universality

Mohammad A. Vasef MD,Charles E. Platz MDAn introduction is given to the problem of calculating the structure factor by means of numerical simulations. The physical importance of the structure factor is emphasized. Several examples including both lattice gas models, continuous models and exact results are discussed.
