Faculty candidate seminar: Na Young Kim

Speaker Na Young Kim
Date: 2/24/2014
Time: 11:00 am
Location: 1000 MNTL
Sponsor: ECE
Event Type: Seminars
  ECE Faculty Candidate Na Young Kim will give a seminar at 11 a.m. Monday, February 24, in Room 1000 MNTL. The talk's title will be, "Microcavity Exciton-Polaritons: Past, Present, and Future." Kim currently works at Stanford University. Microcavity exciton-polaritons are hybrid light-matter quasi-particles as an admixture of cavity photons and quantum well excitons. The inherent light-matter duality provides experimental advantages to form coherent condensates at high temperatures (e.g. 4 K in GaAs and room temperature in GaN materials), and to access the dynamics of exciton-polaritons. Since their first observation in 1992, the research field has been burgeoning in the exploration of the fundamentals and in the development of the photonic devices. Kim will overview key lessons in microcavity exciton-polariton physics as well as the characteristics of microcavity exciton-polariton condensates with the emphasis on their intrinsic open-dissipative nature. Upon the very nature of dynamical condensation, she will show the advantages of microcavity exciton-polaritons for building a quantum simulator machine in the quest for better understanding strongly correlated materials. She will also discuss potential photonic devices, that would feature low operation power and fast speed.
