Quantum Optics Seminar by Martijn Wubs, DTU

TITLE:
Collective emission of coherently coupled solid-state quantum emitters

ABSTRACT:
Coherently coupled quantum emitters in solids can exhibit superradiance,
despite phonon interactions. First, I present a comparison of theories for
collective photon emission that include both markovian and non-markovian
phonon effects [1,2], and a study of plasmonic enhancement of
superradiance from emitters in multilayer 2D materials [3]. Secondly, I will
briefly present experiments on quantum emitters in 2D materials in my
group, in particular in hexagonal boron nitride [4,5] and in twisted bilayer
systems that exhibit moiré physics even at room temperature [6]. Finally, I
will present recent results of a collaboration with our topology optimization
colleagues at DTU, on omnidirectional nanophotonic trapping in dielectric
nanocavities that exhibit extreme dielectric confinement [7].
