A paper entitled Coherent Control of the Exciton-Biexciton System in an InAs Self-Assembled Quantum Dot Ensemble by Former JILA Fellow Steven T. Cundiff's group at the University of Michigan was published online in Physical Review Letters on October 6, 2016. Former JILANs Takeshi Suzuki and Rohan Singh were the paper's first and second authors, respectively. The new paper is both an Editor's Suggestion and is the basis for a highlight entitled "Decoding the Light from Ten Million Quantum Dots," on physics.aps.org.
The paper describes an exciting new technique that reduces smearing that occurs when variations in the size and composition of an ensemble of quantum dots shifts (and smears) the colors of their collectively emitted light.
Principal Investigators
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
