The central-spin problem is a widely studied model of quantum decoherence. Dynamic nuclear polarization occurs in central-spin systems when electronic angular momentum is transferred to nuclear spins and is exploited in quantum information processing for coherent spin manipulation. However, the mechanisms limiting this process remain only partially understood.

Norman Yao Awarded 2015 DAMOP Thesis Prize

Norman Yao

Norman Yao (PhD 2014) has been awarded the 2015 Prize for Outstanding Doctoral Thesis Research in Atomic, Molecular or Optical Physics (the DAMOP Thesis Prize) for his PhD dissertation.

Yao’s prize winning thesis, Topology, Localization, and Quantum Information in Atomic, Molecular and Optical Systems, was motivated by the interface between atomic, molecular and optical (AMO) physics, condensed matter, and quantum information science that has recently led to the development of new insights and tools that bridge the gap between macroscopic quantum behavior and detailed microscopic intuition.
