Energetic positive muons were injected into the back of thin moderators (Lithium-Fluoride, Quartz and Copper), and the transmitted beam energy analyzed.

Tunneling excitations of electrons in dry-etched modulation-doped AlGaAs/GaAs coupled quantum dots (QDs) are probed by resonant inelastic light scattering.

It has long been known that magnetic fields penetrate type II superconductors in the form of quantized superconducting vortices.

Using Corbino samples we have observed oscillatory dc conductance in a high-mobility two-dimensional electron system when it is subjected to crossed microwave and magnetic fields.

We have examined Al(86)Mn(7)Fe(7) and Al(86)Mn(14) melt-spun ribbons by TEM. The microstructure of both alloys consist of the coral-like, rosette shaped grains.

Modal noise has been observed in overmoded short fiber sections and transmitter pigtails resulting in performance degradation in a single-mode fiber transmission system.

We report the first observation of the modulational instability of lightwave propagation in single-mode optical fibers at the anomalous group-velocity dispersion region.

Magnetorotons in the dispersions of collective gap modes of fractional quantum Hall liquids are determined in resonant inelastic scattering experiments.
