  • Bound electron pairs in strongly correlated models of high-temperature superconductivity 
    Boyaci, H.; Kulik, I.O. (Физика низких температур, 1998)
    The ground-state energy of two electrons on a ring is calculated for the one-dimensional Hubbard model with positive and negative on-site interaction and for the contraction model with additive and multiplicative interaction ...
  • Cooper instability in the occupation dependent hopping Hamiltonians 
    Boyaci, H.; Kulik, I.O. (Физика низких температур, 1999)
    A generic Hamiltonian, which incorporates the effect of the orbital contraction on the hopping amplitude between nearest sites, is studied both analytically at the weak coupling limit and numerically at the intermediate ...
