Loss-driven topological transitions in lasing
Grazia Salerno, Rebecca Heilmann, Kristian Arjas +3
We experimentally observe lasing in a hexamer plasmonic lattice and find that when tuning the scale of the unit cell, the polarization winding of the emission changes. By a theoret…
Magnetic on-off switching of a plasmonic laser
Francisco Freire-Fernández, Javier Cuerda, Konstantinos S. Daskalakis +5
The nanoscale mode volumes of surface plasmon polaritons have enabled plasmonic lasers and condensates with ultrafast operation. Most plasmonic lasers are based on noble metals, re…
Strong coupling between organic dye molecules and lattice modes of a dielectric nanoparticle array
Rebecca Heilmann, Aaro I. Väkeväinen, Jani-Petri Martikainen +1
Plasmonic structures interacting with light provide electromagnetic resonances which result in a high degree of local field confinement enabling the enhancement of light-matter int…
Lasing in Ferromagnetic Plasmonic Arrays
Sara Pourjamal, Tommi K. Hakala, Marek Nečada +6
We report on lasing at visible wavelengths in arrays of ferromagnetic Ni nanodisks overlaid with an organic gain medium. We demonstrate that by placing an organic gain material wit…
The Fulde-Ferrell-Larkin-Ovchinnikov state for ultracold fermions in lattice and harmonic potentials: a review
Jami J. Kinnunen, Jildou E. Baarsma, Jani-Petri Martikainen +1
We review the concepts and the present state of theoretical studies of spin-imbalanced superfluidity, in particular the elusive Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, in th…
Bose-Einstein Condensation in a Plasmonic Lattice
Tommi K. Hakala, Antti J. Moilanen, Aaro I. Väkeväinen +6
Bose-Einstein condensation is a remarkable manifestation of quantum statistics and macroscopic quantum coherence. Superconductivity and superfluidity have their origin in Bose-Eins…
