SUMMARY:Electronic\, spin and transport properties of a triple quantum
  dot molecule\, R. G. Herb Condensed Matter Seminar\, Yun-Pil Shim
DESCRIPTION:I will present a theory of lateral triple quantum dot syst
 em in a triangular geometry. In this setting\, the strong Coulomb inte
 raction and the quantum interference effects  play important roles in 
 determining the electronic and spin properties. Configuration-interact
 ion method is used to obtain the many-electron eigenstates and the eff
 ects of magnetic field will be explained. It will be shown that this s
 ystem can be used to realize localized spins  with tunable interaction
 s by using purely electrical methods. Transport through this system wi
 ll be discussed in a simple framework based on rate equations.
