Ground state energy of the fröhlich polaron as a function of dimensionality and the phonon coupling strength
(Bilkent University, 2018-09)We use the trial polaron wave function introduced by Devreese et al. [1] to estimate the ground state energies of the Fröhlich polaron over a broad range of the phonon coupling strength by a variational approach. We ... -
Lasing in a Slow Plasmon Moiré Cavity
(American Chemical Society, 2015)We report on lasing from dye-based excitons coupled to slow plasmon states inside metallic Moiré cavities. Surface plasmon polaritons (SPPs) inside the cavity were slowed down to a maximum group velocity of 0.3c. Varying ... -
Quantum bistability, structural transformation, and spontaneous persistent currents in mesoscopic aharonov-bohm loops
(World Scientific Publishing Co., 2005)Fixed-number-of-electron mesoscopic or macromolecular conducting ring is shown to support persistent currents due to Aharonov-Bohm flux, and the "spontaneous" persistent currents without the flux when structural transformation ... -
Raman enhancement on a broadband meta-surface
(American Chemical Society, 2012-07-30)Plasmonic metamaterials allow confinement of light to deep subwavelength dimensions, while allowing for the tailoring of dispersion and electromagnetic mode density to enhance specific photonic properties. Optical resonances ... -
Strong coupling between localized and propagating plasmon polaritons
(OSA - The Optical Society, 2015)We investigate plasmon-plasmon (PP) coupling in the strongly interacting regimes by using a tunable plasmonic platform consisting of triangular Ag nanoprisms placed nanometers away from Ag thin films. The nanoprisms are ... -
Tunable plexcitonic nanoparticles: a model system for studying plasmon-exciton interaction from the weak to the ultrastrong coupling regime
(American Chemical Society, 2016)Controlling the number of dye molecules on metallic nanoparticles, which in turn affects the magnitude of Rabi splitting energy, is crucial for obtaining hybrid metal core–organic shell nanoparticles with tunable optical ...
