Spintronics
As an alternative to electronic charge, the storage and transport of electronic spin in semiconductor devices - "spintronics", may revolutionize the electronic device industry, with spin based transistors , opto-electronic devices, and memory. Moreover, the ability to preserve coherent spin states in conventional semiconductors and quantum dots may eventually enable quantum computing in the solid state.
Solid State Quantum Information Processing
The fundamental quantum-mechanical nature of spin makes it an ideal candidate for use as a quantum bit, the basic unit of information in a quantum computer. In such systems, individual spins may be initialized, coherently controlled, and read out using a variety of optical and electronic techniques.
Magnetic Semiconductors
The exchange couplings present in magnetically-doped semiconductors are orders of magnitude larger in energy than the spin-orbit and hyperfine interactions, and the interactions between carriers and magnetic ions in magnetic semiconductors may be engineered through the use of molecular beam epitaxy grown heterostructures.
Ferromagnets and Nanomagnets
Due to their intermediate size, mesoscopic magnetic structures occupy a transitional region between the classical and quantum-mechanical worlds of magnetism. This transition is explored as a function of scale with the use of advanced techniques in miniaturization and magnetometry.
Measurement Techniques
Spin phenomena may be quantified to a striking degree of precision using a variety of optical and electronic techniques that enable one to probe spin dynamics as a function of time and space.
