Fano enhancement of second harmonic field via dark-bright plasmon coupling
Mehmet Gunay
Surface plasmon resonances, the coherent oscillation of free electrons, can concentrate incident field into small volumes much smaller than the incident wavelength. The intense fie…
Fano-control of down-conversion in a nonlinear crystal embedded with plasmonic-quantum emitter hybrid structures
Zafer Artvin, Mehmet Günay, Alpan Bek +1
Control of nonlinear response of nanostructures via path interference effects, i.e., Fano resonances, has been studied extensively. In such studies, a frequency conversion process…
A quantum emitter coated with graphene interacting in the strong coupling regime
Mehmet Günay, Vasilios Karanikolas, Ramazan Sahin +3
We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are the exact solutions of 3D Maxwell equations. Interaction produces…
Entanglement criteria for two strongly interacting ensembles
Mehmet Günay, Özgür Esat Müstecaplıoğlu, Mehmet Emre Tasgin
Two interacting atomic ensembles display a Dicke-like quantum phase transition above a critical coupling strength. We show that an ensemble-ensemble entanglement accompanies the qu…
Enhanced spontaneous down-conversion in a nonlinear crystal embedded with plasmonic-quantum emitter hybrid structures
Zafer Artvin, Mehmet Emre Tasgin, Alpan Bek +1
Control of nonlinear response of nanostructures via path interference effects, i.e. Fano resonances, has been studied extensively. In such materials, a frequency conversion process…
