Continuously-tunable Cherenkov-radiation-based detectors via plasmon index control
Mehmet Günay, You-Lin Chuang, Mehmet Emre Tasgin
A recent study [PRB 100, 075427 (2019)], finally, demonstrated plasmon-analog of refractive index enhancement in metal nanostructures, which has already been studied in atomic clou…

Nonclassicality and entanglement for wavepackets
Mehmet Emre Tasgin, Mehmet Gunay, M. Suhail Zubairy
Mode-entanglement based criteria and measures become insufficient for broadband emission, e.g. from spasers (plasmonic nano-lasers). We introduce criteria and measures for the (i)…

Controlling steady-state second harmonic signal via linear and nonlinear Fano resonances
Mehmet Günay, Zafer Artvin, Alpan Bek +1
Nonlinear signal even from a single molecule becomes visible at hot spots of plasmonic nanoparticles. In these structures, Fano resonances can control the nonlinear response in two…
