    • Hofstadter butterfly evolution in the space of two-dimensional bravais lattices 

      Yllmaz, F.; Oktel, M. Ö. (American Physical Society, 2017)
      The self-similar energy spectrum of a particle in a periodic potential under a magnetic field, known as the Hofstadter butterfly, is determined by the lattice geometry as well as the external field. Recent realizations of ...
    • Landau levels in lattices with long - range hopping 

      Atakişi, Hakan; Oktel, M. Özgür (American Physical Society, 2013)
      Landau levels (LLs) are broadened in the presence of a periodic potential, forming a barrier for accurate simulation of the fractional quantum Hall effect using cold atoms in optical lattices. Recently, it has been shown ...
