SUMMARY:Quantum Point Contacts: a Tunable Single-Spin System ? - Prof. J. 
 P. Bird (University of Buffalo\, USA)

CONTACT:K DAS GUPTA
DESCRIPTION:In my talk I will explore the idea that quantum point contacts
  (QPCs) may be\nused as a controlled system for the confinement\, and mani
 pulation\, of single\nelectron spins. Our experiments make use of a novel 
 geometry in which one\nQPC is used to provide electrical readout of the st
 ate of another\, located\nin close proximity to it. Theoretical analysis i
 n support of these\nexperiments suggests that this system may be used to d
 etect the confinement\nof single spins. In my talk I present new experimen
 tal results that provide\ndetailed insight into the microscopic properties
  of this novel localized\nspin.\n
