    • Counterflow in Bose gas bilayers: collective modes and dissipationless drag 

      Abedinpour, S. H.; Tanatar, Bilal (American Institute of Physics, 2020)
      We investigate the collective density oscillations and dissipationless drag effect in bilayer structures of ultra-cold bosons in the presence of counterflow. We consider different types of inter-particle interactions and ...
    • Dimensional crossover in two-dimensional Bose-Fermi mixtures 

      Subaşi, A. L.; Sevinçli, S.; Vignolo, P.; Tanatar, Bilal (Institute of Physics Publishing, 2010)
      We investigate the equilibrium properties of boson-fermion mixtures consisting of a Bose condensate and spin-polarized Fermi gas confined in a harmonic two-dimensional (2D) trap using mean-field theory. Boson-boson and ...
    • Phase boundary of the boson Mott insulator in a rotating optical lattice 

      Umucalilar, R. O.; Oktel, M. Ö. (The American Physical Society, 2007)
      We consider the Bose-Hubbard model in a two-dimensional rotating optical lattice and investigate the consequences of the effective magnetic field created by rotation. Using a Gutzwiller-type variational wave function, we ...
    • Two-dimensional boson-fermion mixtures 

      Subaşi, A.L.; Sevinçli, S.; Vignolo P.; Tanatar, Bilal (2009)
      Using mean-field theory, we study the equilibrium properties of boson-fermion mixtures confined in a harmonic pancake-shaped trap at zero temperature. When the modulus of the s -wave scattering lengths are comparable to ...
