  • Taşgın, Mehmet Emre; Müstecaplıoğlu, Özgür Esat; You, L. (Physical Review, 2011)
    The creation of a topological vortex by a superradiant scattering of a Laguerre-Gaussian (LG) beam off an atomic Bose-Einstein condensate (BEC) is theoretically investigated. It is shown that scattered superradiant radiation ...
  • Taşgın, Mehmet Emre; Oktel, M. Ö. (Institute of Physics Publishing, 2006)
    We investigate the dynamical instability for a two component Bose-Einstein Condensate (BEC) in an optical lattice. We assume that the two components are in sinusoidal potentials with the same period but different phases. ...
  • Taşgın, Mehmet Emre (Nanoscale, 2013)
    We investigate the dynamics of a plasmonic oscillation over a metal nanoparticle when it is strongly coupled to a quantum emitter (e.g. quantum dot, molecule). We simulate the density matrix evolution for a simple model, ...
  • Taşgın, Mehmet Emre; Müstecaplıoğlu, Özgür Esat; Oktel, M. Ö. (Physical Review, 2007)
    We investigate the photonic bands of an atomic Bose-Einstein condensate with a triangular vortex lattice. Index contrast between the vortex cores and the bulk of the condensate is achieved through the enhancement of the ...
  • Taşgın, Mehmet Emre; Oktel, M. Ö.; You, L.; Müstecaplıoğlu, Özgür Esat (Physical Review, 2009)
    We discover an inherent mechanism for entanglement swap associated with sequential superradiance from an atomic Bose-Einstein condensate. Based on careful examinations with both analytical and numerical approaches, we ...
  • Taşgın, Mehmet Emre; Öztop, B.; Oktel, M. Ö.; Müstecaplıoğlu, Özgür Esat (Optics and Spectroscopy, 2009)
    Quantum correlations among atoms in superradiant Bose–Einstein condensates are discussed. It is shown that atoms in the superradiant atomic condensate can exhibit continuous variable quantum entanglement analogous to ...
  • Taşgın, Mehmet Emre; Öktel, M. Ö.; You, L.; Müstecaplıoğlu, Özgür Esat (Laser Physics, 2010)
    We adopt the coherence and builtin swap mechanism in sequential superradiance as a tool for obtaining continuousvariable (electric/magnetic fields) quantum entanglement of two counterpropagating pulses emitted from the two ...
  • Taşgın, Mehmet Emre; Steinke, S. K.; Singh, S.; Meystre, Pierre; Schwab, K. C.; Vengalattore, M. (Physical Review, 2011)
    We study theoretically the dynamics of a hybrid optomechanical system consisting of a macroscopic mechanical membrane magnetically coupled to a spinor Bose-Einstein condensate via a nanomagnet attached at the membrane ...
  • Taşgın, Mehmet Emre; Meystre, Pierre (Physical Review, 2011)
    We analyze theoretically a scheme that produces spin squeezing via the continuous swapping of atom-photon entanglement into atom-atom entanglement, and propose an explicit experimental system where the necessary atom-field ...
  • Taşgın, Mehmet Emre (Physical Review, 2012)
    We introduce a method to test if a given velocity definition corresponds to an actual physical flow in a dispersive medium. We utilize the equivalence of the pulse dynamics in the real-ω and real-k Fourier expansion ...
  • Taşgın, Mehmet Emre; Müstecaplıoğlu, Özgür Esat; Oktel, M. Ö. (Laser Physics, 2008)
    Photonic crystal behavior of a rotating Bose–Einstein condensate with a triangular vortex lattice is reviewed and a scheme for getting much wider band gaps is proposed. It is shown that photonic band gaps can be widened ...
  • Taşgın, Mehmet Emre; Subaşı, A. L.; Oktel, M. Ö.; Tanatar, B. (Journal of Low Temperature Physics, 2005)
    We consider a trapped system of atomic boson-fermion mixture with a quantized vortez. We investigate the density profiles of bosonic and fermionic components as functions of the boson-boson and boson-fermion short-range ...
