The Nature of Topological Protection in Spin and Valley Hall Insulators
Matthias Saba, Stephan Wong, Mathew Elman +2
Recent interest in optical analogues to the quantum spin Hall and quantum valley Hall effects is driven by the promise to establish topologically protected photonic edge modes at t…
Generation of plasmonic hot carriers from d-bands in metallic nanoparticles
Lara Román Castellanos, Juhan Matthias Kahk, Ortwin Hess +1
We present an approach to master the well-known challenge of calculating the contribution of d-bands to plasmon-induced hot carrier rates in metallic nanoparticles. We generalise t…
Plasmonic nanocavity modes: From near-field to far-field radiation
Nuttawut Kongsuwan, Angela Demetriadou, Matthew Horton +3
In the past decade, advances in nanotechnology have led to the development of plasmonic nanocavities which facilitate light-matter strong coupling in ambient conditions. The most r…
Quantum Plasmonic Immunoassay Sensing
Nuttawut Kongsuwan, Xiao Xiong, Ping Bai +4
Plasmon-polaritons are among the most promising candidates for next generation optical sensors due to their ability to support extremely confined electromagnetic fields and empower…
Gapless Unidirectional Photonic Transport Using All-Dielectric Kagome Lattices
Stephan Wong, Matthias Saba, Ortwin Hess +1
Photonic topological insulators are a promising photonic platform due to the possibility of unidirectional edge states with insensitivity to bending, fabrication imperfections or e…
Single plasmon hot carrier generation in metallic nanoparticles
Lara Román Castellanos, Ortwin Hess, Johannes Lischner
Hot carriers produced from the decay of localized surface plasmons in metallic nanoparticles are intensely studied because of their optoelectronic, photovoltaic and photocatalytic…
