QC 351 A7 no. 45 v1 / "The Physics of Quantum Electronics," a two -week, noncredit course sponsored by the Optical Sciences Center, was held from June 15 through June 27, 1969, on the campus of Northern Arizona University in Flagstaff. The course was directed by Professors S.F. Jacobs (University of Arizona) and M.O. Scully (Massachusetts Institute of Technology) and was patterned after the tutorial symposiums sponsored in 1966 and 1967 by Colorado State University, and in 1968 by the University of Arizona. Designed primarily for advanced students, re- search scientists, and technical administrators working in the general area of quantum electronics and coherence physics, the course attracted 90 participants from all over the world. A list of attendees appears at the end of this report.

QC 351 A7 no. 45 v2 / The major areas of quantum electronics are concerned with the generation of electromagnetic fields- -with the theory and operation of stimulated emission devices, stimulated and nonlinear scattering phenomena, etc. A smaller but vital area involves the measurement problem, and explores the ways in which we can determine various properties of optical fields through measurements of intensities, interference, correlations, statistical distributions of photoelectrons, etc. In these lectures we will investigate various techniques for exploring the properties of optical fields. Until some 15 years ago all known optical phenomena could be described by the simple classical theory of elementary optics. In the mid 1950's, two new experiments were reported --the Hanbury- Brown Twiss intensity interferometry experiment, and the light beating experiment of Forrester and coworkers. These experiments generated considerable confusion since many people found in them an apparent violation of well -established physical principles. Subsequently, optics has undergone a revolutionary development with the invention of lasers and the introduction of fast pulse electronics capable of resolving individual photon detection events on a nanosecond time scale or less. The new field of photon statistics has grown rapidly and has already produced a sizable literature. Concurrently with the experimental developments, there has been a rather complete restructuring of the theory of optics which has produced a framework in which all of the newer experiments can be analyzed. A theoretical development has followed two independent paths. A classical theory of optical coherence has been developed, mainly by E. Wolf, based on the earlier work of Gabor and others. More recently, R. J. Glauber has formulated a quantum mechanical theory of optical coherence. Unfortunately, much effort has been expended in trying to prove both the equivalence and the nonequivalence of the two formulations, an undertaking which has produced considerably more heat than light. In these lectures we will attempt to review both the classical and quantum mechanical theories of optical coherence, and will use the results to analyze a variety of experiments. The emphasis throughout will be on gaining physical insight rather than on maintaining mathematical rigor. For those interested in detailed discussions of the theory, references to the literature are included in these notes.

Much experimental research has been performed in the equilibrium regime on individual quantum dots and quantum point contacts (QPCs). The focus of the research presented here is electron transport in the nonequilibrium regime in coupled quantum dot and QPC systems fabricated on AlGaAs/GaAs material using the split gate technique. Near equilibrium magnetoconductance measurements were performed on a quantum dot and a QPC. Oscillations were seen in the conductance of the sensor which corresponded to Aharonov-Bohm oscillations in the quantum dot, to our knowledge the first such observation. Sudden jumps in the conductance of the QPC were observed under certain gate biases and under certain magnetic fields. When the gate biases and magnetic field were held constant and the conductance was observed over time, switching was observed with the form of a random telegraph signal (RTS). RTS switching is usually attributed to charging of a single impurity. However, in this case switching may have been due to tunneling via edge states in the dot. Nonequilibrium transport in single quantum dots was investigated. A knee or kink was observed in the current-voltage characteristics of two dots on different material. The bias conditions under which the knee occurred point to electron heating as the physical mechanism for the observed behavior. However, the data can not be fit accurately over all bias ranges with an energy balance hot electron model. Modifications to the model are needed to accurately represent the devices studied here. Finally, the effect of nonlinear transport through a one dimensional (1D) QPC on the equilibrium conductance of an adjacent OD quantum dot was explored. This was the first attempt to observe Coulomb drag between a OD and 1D system. It was observed that the equilibrium conductance peaks in the quantum dot were broadened as the current in the QPC increased. This apparent electron heating effect in the dot can be explained by a simple ballistic phonon model. However, reasonable phase coherence times can be estimated from peak fitting using a Breit- Wigner formula which points to a Coulomb interaction. More detailed numerical calculations should illuminate the dominant scattering processes. / Graduation date: 1999
