Query: Analysis of the interaction between classical and quantum plasmons via
  FDTD-TDDFT method   A powerful hybrid FDTD--TDDFT method is used to study the interaction between
classical plasmons of a gold bowtie nanoantenna and quantum plasmons of
graphene nanoflakes (GNFs) placed in the narrow gap of the nanoantenna. Due to
the hot-spot plasmon of the bowtie nanoantenna, the local-field intensity in
the gap increases significantly, so that the optical response of the GNF is
dramatically enhanced. To study this interaction between classical and quantum
plasmons, we decompose this multiscale and multiphysics system into two
computational regions, a classical and a quantum one. In the quantum region,
the quantum plasmons of the GNF are studied using the TDDFT method, whereas the
FDTD method is used to investigate the classical plasmons of the bowtie
nanoantenna. Our analysis shows that in this hybrid system the quantum plasmon
response of a molecular-scale GNF can be enhanced by more than two orders of
magnitude, when the frequencies of the quantum and classical plasmons are the
same. This finding can be particularly useful for applications to molecular
sensors and quantum optics.
