    • Ground state energy of the fröhlich polaron as a function of dimensionality and the phonon coupling strength 

      Bayrak, Hamdi Burak (Bilkent University, 2018-09)
      We use the trial polaron wave function introduced by Devreese et al. [1] to estimate the ground state energies of the Fröhlich polaron over a broad range of the phonon coupling strength by a variational approach. We ...
    • Mixtures of charged-neutral superfluids 

      Ünal, Fatmanur (Bilkent University, 2016-12)
      Motivated by the developments of artificial magnetic fields (AMFs) enabling cou- pling to the neutral particles of ultracold quantum gases, we have theoretically studied charged-neutral mixtures in various settings. The ...
    • Superconducting systems of low dimensionality 

      Gedik, M. Zafer (Bilkent University, 1992)
      It is possible to call the last five years as the golden age of superconductivity. The two most important developments in the field are the discovery of copper oxide and fullerene superconductors. In this work, some ...
