    • Drag effect in double-layer dipolar fermi gases 

      Tanatar, Bilal; Renklioğlu, Başak; Öktel, M. Özgür (IOP, 2014)
      We consider two parallel layers of two-dimensional spin-polarized dipolar Fermi gas without any tunneling between the layers. The effective interactions describing screening and correlation effects between the dipoles in ...
    • Dynamical instability of a two component Bose-Einstein Condensate in an optical lattice 

      Taşgın, M. Emre; Öktel, M. Özgür (IOP, 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. ...
    • Refractive index-enhanced vortex lattices 

      Müstecaplıoǧlu, Ö. E.; Öktel, M. Özgür (SPIE, 2005)
      Light propagation through vortex matter in atomic Bose-Einstein condensates is examined. It is shown that vortex matter can be used as a photonic crystal by a refractive index enhancement scheme. Band structure of the ...
    • Temperature-dependent density profiles of dipolar droplets 

      Aybar, Enes; Öktel, M. Özgür (American Physical Society, 2019)
      Recently, trapped dipolar gases were observed to form high-density droplets in a regime where mean-field theory predicts collapse. These droplets present a form of equilibrium where quantum fluctuations are critical for ...
    • Tkachenko modes of the square vortex lattice in a two-component Bose-Einstein condensate 

      Keçeli, Murat; Öktel, M. Özgür (2006)
      We study Tkachenko modes of the square vortex lattice of a two-component Bose-Einstein condensate (BEC) in the mean-field quantum Hall regime, considering the coupling of these modes with density excitations. We derive the ...
