Nonlocality in Nonlinear Quantum Mechanics
W. Luecke
A general method for testing essential nonlocality of nonlinear modifications of quantum mechanics is presented and applied to show the inconsistency of I. Bialynicki-Birula's and…
Gisin Nonlocality of the Doebner-Goldin 2-Particle Equation
W. Luecke
Gisin's argument against deterministic nonlinear Schroedinger equations is shown to be valid for every (formally) nonlinearizable case of the general Doebner-Goldin 2-particle equa…
Nonlinear Quantum Mechanics and Locality
W. Luecke, P. Nattermann
It is shown that, in order to avoid unacceptable nonlocal effects, the free parameters of the general Doebner-Goldin equation have to be chosen such that this nonlinear Schrödinger…
Nonlinear Schroedinger Dynamics and Nonlinear Observables
W. Luecke
It is is explained why physical consistency requires substituting linear observables by nonlinear ones for quantum systems with nonlinear time evolution of pure states. The exact m…
