    Bose-Einstein condensation of noninteracting charged Bose gas in the presence of external potentials
    (Elsevier Science Publishers B.V., 2001) Bayındır, Mehmet; Tanatar, Bilal
    We investigate thermodynamic properties of noninteracting charged bosons in the presence of externally applied electric and magnetic fields. Using the semiclassical density of states, we obtain the condensate fraction, chemical potential, total energy, and specific heat of a system of finite number of charged Bose particles. We conclude that Bose-Einstein condensation of the charged Bose gas occurs in the crossed electric and magnetic fields.

    Drag effect in double-layer dipolar fermi gases
    (IOP, 2014) Tanatar, Bilal; Renklioğlu, Başak; Öktel, M. Özgür
    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 a single layer (intra-layer) and across the layers (interlayer) are modeled within the Hubbard approximation. We calculate the rate of momentum transfer between the layers when the gas in one layer has a steady flow. The momentum transfer induces a steady flow in the second layer which is assumed initially at rest. This is the drag effect familiar from double-layer semiconductor and graphene structures. Our calculations show that the momentum relaxation time has temperature dependence similar to that in layers with charged particles which we think is related to the contributions from the collective modes of the system.

    Plasma modes in layered superconductors
    (Elsevier B.V., 2005) Askerzade, I. N.; Tanatar, Bilal
    An expression for the plasmon spectrum in the layered superconductors with arbitrary thickness of planes, which varies within a wide range is obtained. The obtained result can be attractive for the explanation of experimental data on plasmon modes in cuprates and other recently discovered superconductors.
