By using large single crystals of YBa2Cu3Or, precise temperature and doping dependence of the c-axis infrared active phonons are investigated. The effect of the superconducting gap opening on the phonon self-energy is observed for the optimally doped crystal but not for the overdoped crystal, which

A bound state is found in the strongly correlated electron system described by the Hubbard model. The state is the singlet state of correlated electrons and the binding energy of the state is estimated as 0.03 times the half band width in the case that the band is nearly half-filled by electrons.
