Condensed Matter Theory

Abstract:

We use lattice-Boltzmann simulations to examine late stage spinodal decomposition in binary fluids, showing that the scaling hypothesis for phase ordering does not hold in all cases. We also examine the effects of an applied shear on the coarsening of the spinodal pattern.

Abstract:

We study statistical properties of the eigenvectors of non-Hermitian random matrices, concentrating on Ginibre’s complex Gaussian ensemble, in which the real and imaginary parts of each element of an N × N matrix, J, are independent random variables. Calculating ensemble averages based on the quantity ⟨Lα|Lβ⟩ ⟨Rβ|Rα⟩, where ⟨Lα| and |Rβ⟩ are left and right eigenvectors of J, we show for large N that eigenvectors associated with a pair of eigenvalues are highly correlated if the two eigenvalues lie close in the complex plane. We examine consequences of these correlations that are likely to be important in physical applications. © 1998 The American Physical Society.
