The fine spectral tuning of plasmon mode and quantum emitter coupling and its comparison with the dark-hot resonances
Asif, Hira; Ovalı, Rasim Volga; Şahin, Ramazan (Scientific Technical Research Council Turkey - TUBİTAK, 2022)Localization of incident fields into very small volumes (hot-spots) allows strong light-matter interactions at the hot spots. This makes path interference effects, Fano resonances, visible. Fano resonances can appear due ... -
Quantum emitter interacting with graphene coating in the strong-coupling regime
Günay, Mehmet; Karanikolas, Vasilios; Şahin, Ramazan; Ovalı, Rasim Volga; Bek, Alpan; Taşgin, Mehmet Emre (Amer Physical Soc, 2020)We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are based on solutions of three-dimensional Maxwell equations, using a boundary element method approach. ... -
Single-molecule-resolution ultrafast near-field optical microscopy via plasmon lifetime extension
Ovali, Rasim Volga; Şahin, Ramazan; Bek, Alpan; Taşgın, Mehmet Emre (AIP Publishing, 2021)Metal nanostructures support plasmon oscillations on their surfaces, which normally decay very quickly. Nevertheless, the lifetime of these oscillations can be extended near a longer lifetime particle, e.g., a molecule. ... -
Viscous dissipation effects on entropy generation in heated vertical parallel-plate channels for mixed convection
Akbulut, Uğur; Ovalı, Rasim Volga; Küçük, Haydar (Inderscience Enterprises Ltd, 2017)In this study, effect of viscous dissipation on entropy generation for fully developed incompressible laminar flow mixed convection in vertical parallel-plate channels with asymmetric and symmetric uniform heat fluxes was ...
