There is a paper just published today on the Los Alamos Nat'l Labs preprint site (http://xxx.lanl.gov/abs/quant-ph/9905064) on how to simulate arbitrary nonlinear quantum dynamics. They give examples of existing systems where the effect has already been seen and then give a general description of

Yes, in general that's true, but the authors are considering the case where weak measurements are made and the information is fed back into the system. Quoting from the paper: "...The time evolution of the system with feedback by weak measurement is accordingly given by *rho prime* = U_delta(*
