Nonlinearity and constrained quantum motion
Dorje C. Brody, Anna C. T. Gustavsson, Lane P. Hughston
The dynamical equation satisfied by the density matrix, when a quantum system is subjected to one or more constraints arising from conserved quantities, is derived. The resulting n…
Constrained quantum dynamics
Anna C. T. Gustavsson
We give an overview of the two different methods that have been introduced in order to describe the dynamics of constrained quantum systems; the symplectic formulation and the metr…
Metric approach to quantum constraints
Dorje C. Brody, Anna C. T. Gustavsson, Lane P. Hughston
A new framework for deriving equations of motion for constrained quantum systems is introduced, and a procedure for its implementation is outlined. In special cases the framework r…
Symplectic approach to quantum constraints
Dorje C. Brody, Anna C. T. Gustavsson, Lane P. Hughston
A general prescription for the treatment of constrained quantum motion is outlined. We consider in particular constraints defined by algebraic submanifolds of the quantum state spa…
Entanglement of three-qubit geometry
Dorje C. Brody, Anna C. T. Gustavsson, Lane P. Hughston
Geometric quantum mechanics aims to express the physical properties of quantum systems in terms of geometrical features preferentially selected in the space of pure states. Geometr…
