• Collectively Induced Many-Vortices Topology Via Rotatory Dicke Quantum Phase Transition 

      Das, Priyam; Tasgin, Mehmet Emre; Mustecaplioglu, Ozgur E. (Iop Publishing Ltd, 2016)
      We examine the superradiance of a Bose-Einstein condensate pumped with a Laguerre-Gaussian laser of high winding number, e.g., l = 7. The laser beam transfers its orbital angular momentum (OAM) to the condensate at once ...
    • Engineering Nonlinear Response Of Nanomaterials Using Fano Resonances 

      Turkpence, Deniz; Akguc, Gursoy B.; Bek, Alpan; Tasgin, Mehmet Emre (Iop Publishing Ltd, 2014)
      We show that nonlinear optical processes of nanoparticles can be controlled by the presence of interactions with a molecule or a quantum dot. By choosing the appropriate level spacing for the quantum emitter, one can either ...
