| Geometric Phase Properties in Neutron Optics Experiments |
| Speaker: | Jürgen Klepp (University of Vienna) |
| Abstract: | Special properties of mixed-input phases are investigated experimentally with polarized neutrons. In the first part, I will explain a measurement of spinor phases for mixed input-states undergoing unitary evolutions. Phases of purely dynamical and purely geometric origin are measured as a function of the input purity of the neutron spin-state. Measuring suitable combinations of both, it has been demonstrated that the mixed-state geometric phase is not additive as it is the case for pure states. Nonadditivity is a natural consequence of the definition of the mixed-state phase as weighted average of the phase factors of all pure state components in the density matrix. In the second part, a test of the phase stability under noisy evolution is described. |
