    Description: 

    "Single-, Few- and Many-body Quantum Systems"

    Abstract(s): 

    As originally formulated in the early 20th century, quantum mechanics became the language for describing the microscopic world of single particles. A century later, quantum phenomena have become prevalent in systems from angstrom to millimeter in size, consisting of single, few or countless many particles.

    Deng will review the effort in her lab to create and study experimental quantum systems including nanosized scalable semiconductor quantum dots that contain single excitons and emit single photons, designable semiconductor microcavities that contain collective quantum states composed of a large number of degenerate half-matter, half-light quasi-particles, and few-dot and few-cavity coupled systems.

    Speaker Bio(s): 

    Hui Deng received her Ph.D. degree in applied physics from Stanford University in 2006. In 2006-2008, she was a postdoctoral fellow at the Institute of Quantum Information at the California Institute of Technology. She joined the physics department of the University of Michigan, Ann Arbor, in 2008 and was promoted to associate professor in 2015.

    Her research centers on the discovery, creation, control and applications of quantum states in single-, few- and many-body systems with matter-light couplings. Current projects include: collective quantum states of matter and light in open cavity-QED systems, quantum photonics and plasmonics with wide bandgap materials, and optical vortices. In particular, they study dynamic condensation and lasing of semiconductor exciton-polaritons in novel structures and materials in single and coupled cavities, site-controlled single (In)GaN quantum dots for high-temperature quantum photonic devices, few-emitter quantum plasmonics, and the generation, propagation and high-fidelity detection of optical vortices.

    Her recent awards include the National Science Foundation CAREER Award, the Air Force Office of Scientific Research Young Investigator Program Award and the Elizabeth C. Crosby Research Award from the University of Michigan.
