Magnetic trapping of neutrons
Article Abstract:
Magnetic trapping of neutrons should permit substantial improvement in the measurement of the neutron lifetime tau-n. This research indicates the loading, trapping and detection techniques required to carry out a neutron-lifetime measurement using magnetically trapped ultracold neutrons (UCNs). It has been possible to directly confirm the theoretical prediction of the UCN density in the trap. Further refinement of this approach should produce improved precision in the neutron lifetime measurement.

Bose-Einstein condensation of excitions in bilayer electron systems
Article Abstract:
The study reviews the semiconductor bilayer systems that provide evidence for the phenomenon of an ordered electronic state in which excitions condense into a single quantum state and explain the reasons for excition condensation in the quantum Hall regime. A Bose-Einstein condensation (BEC) is a highly ordered state in which the wavefunction phase is coherent over distances much longer than the separation between individual particles.
