On (non)linear Quantum Mechanics
Peter Nattermann
We review a possible framework for (non)linear quantum theories, into which linear quantum mechanics fits as well, and discuss the notion of ``equivalence'' in this setting. Finall…

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…
