    • Approximate fourier domain expression for bloch-siegert shift 

      Turk, E. A.; Ider, Y. Z.; Ergun, A. S.; Atalar, E. (John Wiley and Sons Inc., 2015)
      Purpose: In this study, a newsimple Fourier domain-based analytical expression for the Bloch-Siegert (BS) shift-based B1 mapping method is proposed to obtain |B1+| more accurately while using short BS pulse durations and ...
    • Charged bosons in a quasi-one-dimensional system 

      Tanatar, B.; Davoudi, B.; Kohandel, M. (American Physical Society, 2000)
      The ground-state properties of a system of charged bosons in a quasi-one-dimensional model with a neutralizing background are investigated within the hypernetted-chain approximation. Strong correlation effects drive the ...
    • Circuit partitioning using mean field annealing 

      Bultan, T.; Aykanat, C. (Elsevier, 1995)
      Mean field annealing (MFA) algorithm, proposed for solving combinatorial optimization problems, combines the characteristics of neural networks and simulated annealing. Previous works on MFA resulted with successful mapping ...
    • Density profile of a Bose-Einstein condensate inside a pancake-shaped trap: Observational consequences of the dimensional cross-over in the scattering properties 

      Tanatar, B.; Minguzzi, A.; Vignolo, P.; Tosi, M. P. (Elsevier Science B.V., 2002)
      It is theoretically well known that two-dimensionality of the scattering events in a Bose-Einstein condensate introduces a logarithmic dependence on density in the coupling constant entering a mean-field theory of the ...
    • Dynamic correlation effects on the plasmon dispersion in a two-dimensional electron gas 

      Yurtsever, A.; Moldoveanu, V.; Tanatar, B. (The American Physical Society, 2003)
      The charge-density oscillations (plasmons) of a low-density two-dimensional uniform electron gas are studied within the framework of finite temperature and frequency dependent (dynamic) version of Singwi, Tosi, Land, and ...
    • Guiding, bending, and splitting of electromagnetic waves in highly confined photonic crystal waveguides 

      Bayindir, M.; Ozbay, E.; Temelkuran, B.; Sigalas, M. M.; Soukoulis, C. M.; Biswas, R.; Ho, K. M. (American Physical Society, 2001)
      We have experimentally demonstrated the guiding, bending, and splitting of electromagnetic (EM) waves in highly confined waveguides built around three-dimensional layer-by-layer photonic crystals by removing a single rod. ...
    • Intravascular extended sensitivity (IVES) MRI antennas 

      Susil, R. C.; Yeung, C. J.; Atalar, E. (John Wiley & Sons, Inc, 2003)
      The design and application of an intravascular extended sensitivity (IVES) MRI antenna is described. The device is a loopless antenna design that incorporates both an insulating, dielectric coating and a winding of the ...
    • Negative refraction and superlens behavior in a two-dimensional photonic crystal 

      Moussa, R.; Foteinopoulou, S.; Zhang, L.; Tuttle, G.; Guven, K.; Ozbay, E.; Soukoulis, C. M. (American Physical Society, 2005)
      We experimentally and theoretically studied a left-handed structure based on a photonic crystal (PC) with a negative refractive index. The structure consists of triangular array of rectangular dielectric bars with dielectric ...
    • A sketch of a system of theory and practice 

      Alexander, J. (Sage Publications Ltd, 2015)
      Most political theorists are committed to one particular view about the relation between theory and practice. It is argued in this article that there are in fact four possible ways of relating theory and practice, which ...
    • Spin correlations in electron liquids: Analytical results for the local-field correction in two and three dimensions 

      Tanatar, B.; Mutluay, N. (Springer, 1998)
      We study the spin correlations in two- and three-dimensional electron liquids within the sum-rule version of the self-consistent field approach of Singwi, Tosi, Land, and Sjölander. Analytic expressions for the spin-antisymmetric ...
    • Spin-dependent analysis of two-dimensional electron liquids 

      Bulutay, C.; Tanatar, B. (The American Physical Society, 2002)
      Two-dimensional electron liquid (2D EL) at full Fermi degeneracy is revisited, giving special attention to the spin-polarization effects. First, we extend the recently proposed classical-map hypernetted-chain (CHNC) technique ...
    • SPT-function and its properties 

      Gezmiş, Oğuz (Bilkent University, 2014)
      In this thesis, we survey some properties of the spt-function. We start with providing some background information for q-series and the partition function p(n). Then we define the spt-function and study its generating ...
    • A systematic theory of tradition 

      Alexander, J. (Brill Academic Publishers, 2016)
      We still lack a systematic or complete theory of tradition. By referring to the works of many major figures of the last century - Arendt, Boyer, Eisenstadt, Eliot, Gadamer, Goody, Hobsbawm, Kermode, Leavis, MacIntyre, ...
