In this report the quantum noise properties of phase-insensitive and phase-sensitive parametric processes are studied.

In a recent report (ITD-05-46049D), formulas were derived for the field-quadrature and photon-number means and variances of optical modes that participate in phase- insensitive and phase-sensitive

The temperature and magnetic field dependences of the resonant frequency and dissipation of a mechanical oscillator containing a two-dimensional electron system have been measured.

The temperature and magnetic field dependencies of the resonant frequency and dissipation of a mechanical oscillator containing a two-dimensional electron system have been measured.

Magneto-oscillations have, for the first time, been observed in the thermal conductance of GaAs/AlGaAs heterostructures containing two-dimensional electron systems.

Lattice instabilities are the mechanisms which place upper bounds on T sub c in theoretical models of superconductivity based on dynamical electron-phonon interactions.

Chemical trends in metallic and superconductive properties of these materials are incompatible with theoretical models based on formal carrier density alone.

We review recent inelastic light scattering results that shed light on the interplay between incompressible and compressible quantum phases of electron bilayers at total filling factor nu(T) = 1.

The extreme softening of spin-excitations in electron double-layers is studied by resonant inelastic light scattering.

These tutorial discusses the following: quantum optics; signals and noise in transmission links; and information capacities of transmission links.
