Group-theoretic treatment of strong light-matter coupling with an arbitrary number of excitations
Antti Peltola, Olli Siltanen, Kimmo Luoma +1
Strong light-matter interactions in optical microcavities give rise to hybrid light-matter states known as polaritons. While actively used in modern technologies, theoretical descr…
Enhanced Delayed Fluorescence in Non-Local Metasurfaces: The Role of Electronic Strong Coupling
Yu-Chen Wei, Chih-Hsing Wang, Konstantinos S. Daskalakis +3
Strong light-matter coupling has garnered significant attention for its potential to optimize optoelectronic responses. In this study, we designed open cavities featuring non-local…
Impact of light-matter coupling strength on the efficiency of microcavity OLEDs: A unified quantum master equation approach
Olli Siltanen, Kimmo Luoma, Konstantinos S. Daskalakis
Controlling light-matter interactions is emerging as a powerful strategy to enhance the performance of organic light-emitting diodes (OLEDs). By embedding the emissive layer in pla…
Giant Rabi splitting and polariton photoluminescence in an all solution-deposited dielectric microcavity
Hassan A. Qureshi, Michael A. Papachatzakis, Ahmed Gaber Abdelmagid +4
Planar microcavity polaritons have recently emerged as a promising technology for improving several performance characteristics of organic light-emitting diodes, photodiodes and ph…
Enhancing the efficiency of polariton OLEDs in and beyond the single-excitation subspace
Olli Siltanen, Kimmo Luoma, Andrew J. Musser +1
Organic light-emitting diodes (OLEDs) have redefined lighting with their environment-friendliness and flexibility. However, only 25 % of the electronic states of organic molecules…
Linear optical properties of organic microcavity polaritons with non-Markovian Quantum State Diffusion
Timo Leppälä, Ahmed Gaber Abdelmagid, Hassan A. Qureshi +2
Hybridisation of the cavity modes and the excitons to polariton states together with the coupling to the vibrational modes determine the linear optical properties of organic semico…
Identifying the origin of delayed electroluminescence in a polariton organic light-emitting diode
Ahmed Gaber Abdelmagid, Hassan A. Qureshi, Michael A. Papachatzakis +6
Modifying the energy landscape of existing molecular emitters is an attractive challenge with favourable outcomes in chemistry and organic optoelectronic research. It has recently…
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…
Spatial and Temporal Coherence in Strongly Coupled Plasmonic Bose-Einstein Condensates
Antti J. Moilanen, Konstantinos S. Daskalakis, Jani M. Taskinen +1
We report first-order spatial and temporal correlations in strongly coupled plasmonic Bose-Einstein condensates. The condensate is large, more than twenty times the spatial coheren…
Sub-picosecond thermalization dynamics in condensation of strongly coupled lattice plasmons
Aaro I. Väkeväinen, Antti J. Moilanen, Marek Nečada +3
Bosonic condensates offer exciting prospects for studies of non-equilibrium quantum dynamics. Understanding the dynamics is particularly challenging in the sub-picosecond timescale…
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…
Room-temperature superfluidity in a polariton condensate
Giovanni Lerario, Antonio Fieramosca, Fábio Barachati +8
Superfluidity---the suppression of scattering in a quantum fluid at velocities below a critical value---is one of the most striking manifestations of the collective behaviour typic…
