On the Staruszkiewicz Modification of the Schroedinger Equation
Waldemar Puszkarz
We discuss Staruszkiewicz's nonlinear modification of the Schrödinger equation. It is pointed out that the expression for the energy functional for this modification is not unique…
Non-separability without Non-separability in Nonlinear Quantum Mechanics
Waldemar Puszkarz
We show an example of benign non-separability in an apparently separable system consisting of free non-correlated quantum particles, solitonic solutions to the nonlinear phase…
On Solutions to the Nonlinear Phase Modification of the Schroedinger Equation
Waldemar Puszkarz
We present some physically interesting, in general non-stationary, one-dimensional solutions to the nonlinear phase modification of the Schrödinger equation proposed recently. The…
Energy Ambiguity in Nonlinear Quantum Mechanics
Waldemar Puszkarz
We observe that in nonlinear quantum mechanics, unlike in the linear theory, there exists, in general, a difference between the energy functional defined within the Lagrangian form…
Is an Electromagnetic Extension of the Schroedinger Equation Possible?
Waldemar Puszkarz
The idea of equivalence of the free electromagnetic phase and quantum-mechanical one is investigated in an attempt to seek modifications of Schrödinger's equation that could realiz…
Model of the gravitational dipole
Waldemar Puszkarz
A model of the gravitational dipole is proposed in a close analogy to that of the global monopole. The physical properties and the range of validity of the model are examined as is…
