    • The ground state and vortices in a two-dimensional Bose gas confined in a harmonic trap 

      Tanatar, Bilal (Institute of Physics Publishing, 2002)
      We study the ground state properties of a two-dimensional Bose gas in an harmonic trap potential using the recently proposed mean-field equation that takes into account the correct dimensionality effect. In contrast to the ...
    • q-Gaussian trial function in high density Bose-Einstein condensates 

      Erdemir, E.; Tanatar, Bilal (Elsevier Science B.V., 2003)
      We study the ground-state static properties of Bose-Einstein condensates in the high density regime using a trial wave function of the form of a q-Gaussian. The flexibility afforded by a q-Gaussian trial function yields ...
    • Strongly interacting one-dimensional Bose-Einstein condensates in harmonic traps 

      Tanatar, Bilal; Erkan, K. (American Physical Society, 2000)
      The properties of strongly interacting one dimensional boson condensates in harmonic trap potentials were studied. An equation describing the condensate wave function in the limit of very strong interactions between the ...
    • Surface-state emission enhancement in white-luminophor CdS nanocrystals using localized plasmon coupling 

      Özel, Tuncay; Soğancı, İbrahim Murat; Nizamoğlu, Sedat; Huyal, İlkem Özge; Mutlugün, Evren; Sapra, S.; Gaponik, N.; Eychmüller, A.; Demir, Hilmi Volkan (IEEE, 2008-11)
      To make surface-state emission stronger than band-edge emission for the first time, we proposed and demonstrated plasmon coupling of the surface-state emission from the traps in these CdS nano-luminophors using localized plasmons.
    • Thermally stimulated current observation of trapping centers in undoped GaSe layered single crystals 

      Gasanly, N. M.; Aydınlı, A.; Salihoglu, Ö. (Wiley, 2001)
      Undoped p-GaSe layered single crystals were grown using Bridgman technique. Thermally stimulated current measurements in the temperature range of 10-300 K were performed at a heating rate of 0.18 K/s. The analysis of the ...
    • Thermally stimulated currents in layered Ga4SeS3 semiconductor 

      Aytekin, S.; Yuksek, N.S.; Goktepe, M.; Gasanly, N.M.; Aydınlı, Atilla (2004)
      Thermally stimulated current (TSC) measurements are carried out on nominally undoped Ga4SeS3 layered semiconductor samples with the current flowing along the c-axis in the temperature range of 10 to 150 K. The results are ...
    • Trapping centers in undoped GaS layered single crystals 

      Gasanly, N. M.; Aydınlı, Atilla; Yüksek, N. S.; Salihoglu, Ö. (Springer, 2003)
      Nominally undoped p-GaS layered single crystals were grown using the Bridgman technique. Thermally stimulated current measurements in the temperature range 10-300 K were performed at a heating rate of 0.10 K/s. The analysis ...
    • Two-dimensional boson-fermion mixtures in harmonic traps 

      Tanatar, Bilal; Erdemir, E. (Elsevier Science B.V., 2003)
      The density profiles of bosonic and fermionic components in a system of trapped two-dimensional (2D) boson-fermion (BF) mixture are studied. We employ the variational approach to minimize the total energy functional of the ...
