The quasiparticle excitation spectrum is calculated for the nearly free electron metals Li, Na, and Al by evaluation of the electron self energy operator within the GW approximation and a general

Transport and thermodynamic experiments have verified the suggestion that superconductivity in heavy Fermions is not of the conventional type.

The quasiparticle spectrum of a two-dimensional d-wave superconductor in the mixed state, H sub (c1) H

Theory predicts that quasiparticle tunneling between the counter- propagating edges in a fractional quantum Hall state can be used to measure the effective quasiparticle charge e and dimensionless

We present measurements of the phase diagram for a nonlinear electronic oscillator circuit which has three intrinsic frequencies.

We demonstrate a quasiphase matching scheme for second-harmonic generation in quantum cascade lasers with integrated resonant nonlinearity.

Arithmetic operations involving complex numbers are widely used in the signal processing functions of the physical layer of modern wireless and wireline communication systems, electronic instrument

We demonstrate for the first time that large quantum confined Stark effect can be obtained in high quality InGaAsP/InP quantum well p-i-n heterostructures.

We study dissipation effects for electroncs on the surface of liquid helium, which may serve as qubits of a quantum computer.
