Nanoparticle Arrays for Efficient Organic Light-Emitting Diode Emission Management
Aron J. J. Dahlberg, Matas Gužauskas, Malek Mahmoudi +16
OLEDs are increasingly applied in illumination and displays because they offer excellent color quality, are mechanically flexible, and are self-emissive. However, their usage is li…
Flat Bands from Diffraction in Periodic Systems
Joel Lehikoinen, Rebecca Heilmann, Aron J. J. Dahlberg +5
Periodic photonic structures enable precise control over the light-matter interaction through band structure engineering. Certain lattice geometries exhibit dispersionless flat ban…
Chains of nanoparticles for flat-band emission and lasing
Rebecca Heilmann, Joel Lehikoinen, Sioneh Eyvazi +2
Controlling light-matter interactions is central to photonic technologies ranging from lasers to optical information processing. Suitably designed photonic structures give rise to…
Topological transitions of gapless paired states in mixed-geometry lattices
Dong-Hee Kim, Joel S. J. Lehikoinen, Päivi Törmä
We propose a mixed-geometry system of fermionic species selectively confined in lattices of different geometry. We investigate how such asymmetry can lead to exotic multiband fermi…
Glassy phases and driven response of the phase-field-crystal model with random pinning
E. Granato, J. A. P. Ramos, C. V. Achim +4
We study the structural correlations and the nonlinear response to a driving force of a two-dimensional phase-field-crystal model with random pinning. The model provides an effecti…
