In this thesis, we focus on two broad categories of problems, exciton condensation and bound states, and two complimentary approaches, real and momentum space, to solve these problems. In chapter 2 we...
This dissertation is organized as follows. Beginning with physical background discussions of many-body problems, Chapter 1 introduces the central Kohn-Sham equations of Density Functional Theory for e...
The performance of ground to deep space optical communication systems is degraded by distortion of the beam as it propagates through the turbulent atmosphere. Turbulence causes fluctuations in the ...
This paper proposes current-mode first-order log-domain filters, which are systematically derived using the state-space synthesis procedure. First-order low-pass, high-pass, and all-pass responses are...
Emerging Bio-engineering fields such as Brain Computer Interfaces, neuroprothesis devices and modeling and simulation of neural networks have led to increased research activity in algorithms for th...
The Online Journal of Space Communication is a cross-disciplinary scholarly publication designed to advance space communication as a profession and as an academic discipline.
starting with the light transmission properties in atmosphere, analyzed the characteristics of light power gain for FSO system, the dynamic range of light power gain was also discussed. A innovation p...
The research of determining the small signal equivalent circuit of the real space transfer (RST) transistor is investigated in this work. We propose a voltage-controlled mode model, called parameter e...
DC and AC performances of a GaAs/InGaAs/AIGaAs negative resistance field-effect transistor (NERFET) are demonstrated by molecular beam epitaxy (MBE) for the first time. The negative differential resis...
Nuclear electronic instruments for the measurement of the precise energy and time-of-flight of charged particles, e.g. heavy ions, are quite often present on scientific satellites. In addition to the ...
