DESCRIPTION:“Engineering Nanophotonic Interfaces to Control Plasmons and 
 Spins”\n\nABSTRACT:\n\nLight-matter interactions mediated by photonic qu
 asiparticles play a crucial role in realizing next-generation photonic dev
 ices by unlocking phenomena that are not accessible with free-space photon
 s and providing efficient interfaces for quantum systems. In the first par
 t of the presentation\, I will present the first experimental demonstratio
 n of a mid-infrared light-emitting mechanism originating from an ultrafast
  coupling of optically excited carriers into hot plasmon excitations in gr
 aphene. Such excitations show gate-tunable\, non-Planckian emission charac
 teristics due to the atom-level confinement of the electromagnetic states.
  These findings for plasmon emission in photo-inverted graphene open a new
  path for the exploration of mid-infrared emission processes\, and this me
 chanism can potentially be exploited for both far-field and near-field app
 lications for strong optical field generation. In the second part of the p
 resentation\, I will present a diamond resonant metasurface that can media
 te efficient spin-photon interactions and enable a new type of quantum ima
 ging system. This quantum metasurface containing nitrogen-vacancy (NV) spi
 n ensembles coherently encodes information about the local magnetic field 
 on spin-dependent phase and amplitude changes of near-telecom light. The p
 rojected performance makes the studied quantum imaging metasurface appeali
 ng for the most demanding applications such as imaging through scattering 
 tissues and spatially resolved chemical NMR detection.\n\nBIOGRAPHY:\n\nLa
 ura Kim is currently an IC Postdoctoral Fellow in the Quantum Photonics La
 boratory at the Massachusetts Institute of Technology. She received her B.
 S. degree in chemical engineering and Ph.D. degree in materials science\, 
 both from the California Institute of Technology. She is an EECS Rising St
 ar and a recipient of Gary Malouf Foundation Award and National Science Fo
 undation Graduate Research Fellowship. Her doctoral research focused on un
 derstanding photonic-quasiparticle-driven light-matter interactions in low
  dimensional materials. Her current research involves developing nanoscale
  quantum sensing and imaging strategies.​
