Generalized Darboux transformations for the KP equation with self-consistent sources

, 2004
The KP equation with self-consistent sources (KPESCS) is treated in the framework of the constrained KP equation. This offers a natural way to obtain the Lax representation for the KPESCS.

New transformation of Wigner operator in phase space quantum mechanics for the two-mode entangled case

, 2009
As a natural extension of Fan's paper (arXiv: 0903.1769vl [quant-ph]) by employing the formula of operators' Weyl ordering expansion and the bipartite entangled state representation we find new two-fold complex integration transformation about the Wigner
