    • Cooling quantum gases with entropy localization 

      Ünal, F. Nur; Mueller, Erich J. (Institute of Physics Publishing, 2017)
      We study the dynamics of entropy in a time dependent potential and explore how disorder influences this entropy flow. We show that disorder can trap entropy at the edge of the atomic cloud enabling a novel cooling method. ...
    • Effect of disorder on the interacting fermi gases in a one-dimensional optical lattice 

      Xianlong, G.; Polini, M.; Tosi, M. P.; Tanatar, Bilal (World Scientific Publishing Co., 2008)
      Interacting two-component Fermi gases loaded in a one-dimensional (1D) lattice and subjected to a harmonic trapping potential exhibit interesting compound phases in which fluid regions coexist with local Mott-insulator ...
    • Investigating dirty crossover through fidelity suscepribility and density of states 

      Khan, A.; Basu, S.; Tanatar, Bilal (World Scientific Publishing, 2014)
      We investigate the BCS-BEC crossover in an ultracold atomic gas in the presence of disorder. The disorder is incorporated in the mean-field formalism through Gaussian fluctuations. We observe evolution to an asymmetric ...
    • Metamaterials with negative permeability and negative refractive index: Experiments and simulations 

      Özbay, Ekmel; Guven, K.; Aydin, K. (Institute of Physics Publishing Ltd., 2007)
      We report the transmission characteristics of split-ring resonator and left-handed metamaterials (LHM) in the microwave frequency regime. A left-handed transmission band is observed at the frequencies where both dielectric ...
    • Plasmons and the drag effect in a strong magnetic field 

      Manolescu, A.; Tanatar, Bilal (Elsevier B.V., 2002)
      We study the effect of magnetoplasmons on the drag resistance in a strong magnetic field, at finite temperatures. The typical magnetic field is about 1 T, and the temperature is up to 10 K. The Landau levels are broadened ...
