Geometrical Phases And Symmetries In Dissipative Systems, Adam S. Landsberg Aug 1992

Geometrical Phases And Symmetries In Dissipative Systems, Adam S. Landsberg

WM Keck Science Faculty Papers

A geometrical phase is constructed for dissipative dynamical systems possessing continuous symmetries. It emerges as the natural analog of the holonomy associated with the adiabatic variation of parameters in quantum-mechanical and classical Hamiltonian systems. In continuous media, the physical manifestation of this phase is a spatial shift of a wave pattern, typically a translation or rotation. An illustration associated with pattern formation in fluids is provided.


Recoil Effects And Cp Violation In Neutron Scattering, Vladimir Gudkov Jul 1992

Recoil Effects And Cp Violation In Neutron Scattering, Vladimir Gudkov

Faculty Publications

The problem of the imitation of CP violation in neutron scattering is discussed. The thermal motion of nuclei cannot contribute to symmetry-violating effects. The influence of the nuclear depolarization due to neutron scattering is estimated.

Quantum Action Variable Description Of Bound And Scattering States , Mirley K. Balasubramanya

Retrospective Theses and Dissertations

We present generalized definitions of the classical and quantum radial action variables for both bound and scattering states of a particle moving in the Yukawa potential. The classical action variable is defined as an integral over a contour in the complex radial coordinate plane of the classical momentum function. The quantum action variable is similarly defined as an integral over the same contour of the quantum momentum function. The extension of these definitions of the action variable to other central potentials is discussed.
