    • Electromagnetically induced left-handedness in a dense gas of three-level atoms 

      Oktel, M. Ö.; Müstecaphoǧlu, Ö. E. (The American Physical Society, 2004)
      Ways in which a three-level system can be used to change the frequency-dependent magnetic permeability of an atomic gas were discussed. The resulting macroscopic electrodynamics was also discussed. The two levels were ...
    • SU(2)-path integral investigation of Holstein dimer 

      Hakioğlu, A. T.; Ivanov, V. A.; Zhuravlev, M. Ye. (Elsevier Science Publishers B.V., Amsterdam, Netherlands, 2000)
      The SU(2) coherent state path integral is used to investigate the partition function of the Holstein dimer. This approach naturally takes into account the symmetry of the model. The ground-state energy and the number of ...
