Conditions for separability in generalized Laplacian matrices and nonnegative matrices as density matrices
Chai Wah Wu
Recently, Laplacian matrices of graphs are studied as density matrices in quantum mechanics. We continue this study and give conditions for separability of generalized Laplacian ma…

Perturbation of coupling matrices and its effect on the synchronizability in arrays of coupled chaotic systems
Chai Wah Wu
In a recent paper, wavelet analysis was used to perturb the coupling matrix in an array of identical chaotic systems in order to improve its synchronization. As the synchronization…
