All-optical switching of continuous-variable entanglement in an absorption-suppressed plasmonic nanodimer
Elif Ozturk, Mehmet Gunay, Ramazan Sahin +1
A subwavelength quantum-photonic circuit element should simultaneously generate nonclassical light, suppress plasmonic loss, and remain dynamically tunable. We show that an orthogo…
Active tuning of ENZ resonances in meta-antenna through phase modulation of optical pulse
Elif Ozturk, Hira Asif, Mehmet Gunay +2
Plasmonic nanoantennas offer new avenues to manipulate the propagation of light in materials due to their near field enhancement and ultrafast response time. Here we investigate th…
Optically tunable linear and nonlinear enhancement of index of refraction
Elif Ozturk, Hira Asif, Mehmet Gunay +2
Control of optical properties of materials by tuning their refractive index can revolutionize the current state-of-the-art technology to manipulate light propagation in the high lo…
Environmental-induced work extraction
Rasim Volga Ovali, Shakir Ullah, Mehmet Gunay +1
A local measurement extracts work as a backaction, e.g., in a system of two entangled cavities: first cavity, , comprises a piston and the measurement is carried out on the seco…
Electrically-programmable frequency comb for compact quantum photonic circuits
Shakir Ullah, Mehmet Emre Tasgin, Rasim Volga Ovali +1
Recent efforts have demonstrated the first prototypes for compact and programmable photonic quantum computers (PQCs). Utilization of time-bin encoding in loop-like architectures en…
Environmental-induced work extraction
Rasim Volga Ovali, Shakir Ullah, Mehmet Günay +1
A measurement can extract work from an entangled, e.g., two-mode system. Here, we inquire the extracted work when no intellectual creature, like an ancilla/daemon, is present. When…
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…
Fano Enhancement of Unlocalized Nonlinear Optical Processes
Mehmet Günay, Ahmet Cicek, Nurettin Korozlu +2
Field localization boosts nonlinear optical processes at the hot spots of metal nanostructures. Fano resonances can further enhance these "local" processes taking place at the hot…
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…
Ultra-high resolution aSNOM imaging at off-resonant wavelengths
Ramazan Sahin, Mehmet Gunay, Alpan Bek +1
An atomic force microscope~(AFM) tip, with a few nm-thick noble metal coating, gives rise to strong electric-field at the near-field of tip apex, i.e. hot spot, when illuminated wi…
Weakly Anisotropic Noncentrosymmetric Superconductors with Radial Line Nodes and Thermodynamical Anomalies
Mehmet Günay, T. Hakioğlu, Hasan Hüseyin Sömek
In noncentrosymmetric superconductors (NCSs), the inversion symmetry (IS) is most commonly broken by an antisymmetric spin-orbit coupling (SOC) removing the spin degeneracy and spl…
Radial Line Nodes in Weakly Anisotropic Noncentrosymmetric Superconductors
Mehmet Günay, T. Hakioğlu
Noncentrosymmetric superconductors (NCSs) without inversion symmetry (IS) have a doublet of mixed parity order parameters (OPs) which can have nodes. In addition to the angular lin…
