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…
Emergent force in a bilayer superfluid Bose-Fermi mixture
Mehmet Günay
We investigate a system of two-atomic species in mixed dimensions, in which one species is spread in a three-dimensional space and the other species is confined in two parallel lay…
A binary mixture of Bose-Einstein-condensates in a double-well potential: Berry phase and two-mode entanglement
Mehmet Günay
A binary mixtures of Bose-Einstein condensate structures exhibit an incredible richness in terms of holding different kinds of phases. Depending on the ratio of the inter- and intr…
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…
