The total phase acquired during an evolution of a quantal system has two components: the usual dynamical phase, $\ensuremath{-}1/\ensuremath{\Elzxh}\ensuremath{\int}H(t)dt,$ given by the integrated expectation value of the Hamiltonian, and a geometri

We present results of the first experiment clearly demarcating geometric and dynamical phases. These two phases arise from two distinct physical operations, a rotation and a linear translation, respectively, performed on two identical spin flippers i

Scanning tunnelling microscopy (STM) was employed to study the surface of c -axis oriented YBCO thin films. The films with a thickness of typically about 300 nm were grown onto single crystal (100) MgO by pulsed laser deposition. In addition to the w

Electrons emitted from single-atom tips are analysed in a model with the tip as a round tubelike constriction. The source creates two-dimensional minimum wavepackets whose temporal evolution agrees well with observed beam divergences. With few-atom t

Polarized neutron interferometry has been used to measure the amplitudes for the exchange of up to five photons between the neutron and an oscillating magnetic field. The Rabi spin flip configuration and a configuration in which spin flip is suppress

The photon energy spectra from radiative muon capture on {sup 12}C, {sup 16}O, and {sup 40}Ca have been measured using a time projection chamber as a pair spectrometer. The branching ratio for radiative muon capture is sensitive to {ital g}{sub {ital
