Abstract:
Charge neutrality, a spin 1/2 and an associated magnetic moment of the neutron make it an ideal probe of quantal spinor evolutions.
Polarized neutron interferometry in magnetic field Hamiltonians has thus scored several firsts such as direct verification
of Pauli anticommutation, experimental separation of geometric and dynamical phases and observation of non-cyclic amplitudes
and phases. This paper provides a flavour of the physics learnt from such experiments.
