    • Dynamic correlation effects on the plasmon dispersion in a two-dimensional electron gas 

      Yurtsever, A.; Moldoveanu, V.; Tanatar, Bilal (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 ...
    • Ladder approximation in coupled quantum-well systems 

      Yurtsever, A.; Tanatar, Bilal (American Physical Society, 2001)
      We study the contact values of the interlayer pair-correlation function in electron-electron and electron-hole double-layer systems. For this purpose the ladder approximation as generalized to multicomponent systems is ...
    • Many-body effects in the Coulomb drag between low density electron layers 

      Yurtsever, A.; Moldoveanu, V.; Tanatar, Bilal (Elsevier Science, 2003)
      Recent Coulomb drag experiments in low-density double-layer electron systems have the power of distinguishing various many-body formulations of the effective interactions. In this work we theoretically study the correlation ...
    • Model boson fluid with disorder in the self-consistent field approximation 

      Yurtsever, A.; Tanatar, Bilal (2001)
      We study the ground-state properties of a model neutral boson fluid in the presence of disorder effects. The effective interaction between the bosons is obtained through the self-consistent field method which renormalizes ...
    • Short-range correlations in coupled quantum-wire systems 

      Yurtsever, A.; Tanatar, Bilal (TÜBİTAK, 2002)
      We study the contact values of the inter-wire pair-correlation function in electron-electron and electron-hole double-wire systems. For this purpose the ladder approximation as generalized to multicomponent systems is used. ...
