High topological charge lasing in quasicrystals
Kristian Arjas, Jani M. Taskinen, Rebecca Heilmann +2
Photonic modes exhibiting a polarization winding akin to a vortex possess an integer topological charge. Lasing with topological charge 1 or 2 can be realized in periodic lattices…
Pseudospin-orbit coupling and non-Hermitian effects in the Quantum Geometric Tensor of a plasmonic lattice
Javier Cuerda, Jani M. Taskinen, Nicki Källman +2
We theoretically predict the full quantum geometric tensor, comprising the quantum metric and the Berry curvature, for a square lattice of plasmonic nanoparticles. The gold nanopar…
Observation of Quantum metric and non-Hermitian Berry curvature in a plasmonic lattice
Javier Cuerda, Jani M. Taskinen, Nicki Källman +2
We experimentally observe the quantum geometric tensor, namely the quantum metric and the Berry curvature, for a square lattice of radiatively coupled plasmonic nanoparticles. We o…
Polarization and phase textures in lattice plasmon condensates
Jani M. Taskinen, Pavel Kliuiev, Antti J. Moilanen +1
Polarization textures of light may reflect fundamental phenomena such as topological defects, and can be utilized in engineering light beams. Three main routes are applied during t…
