A simple way to avoid metastable configurations in the density-matrix renormalization-group algorithms
spin model DMRG spin-1
2010/7/8
We use the spin-1 Heisenberg chain with periodic boundary conditions to ilustrate that the systems get stuck in metastable configurations only when the density-matrix renormalization-group algorithm s...
Silica Nanoparticles Dispersed in a Self-assembled Viscoelastic Matrix: Structure, Rheology, and Comparison to Reinforced Elastomers
colloid-polymer mixtures microemulsions rheology small angle neutron scattering
2010/7/5
Model self-assembled networks of telechelic polymer C18 −PEO(35k)−C18 in water have been studied. The rheology of such transient networks has been investigated as a function of polymer con...
Multiple Scales Method for a Matrix KdV Equation
matrix non-linear Schrö dinger equation Matrix Korteweg-de Vries equation
2010/4/19
In this paper the method of multiple scales is used to derive an integrable matrix non-linear Schrödinger equation (MNLS) as an amplitude equation from the Matrix Korteweg-de Vries equation (MKdV...
