Abstract

Based on the experimental ARPES data we have shown that the band structure of high T c compounds is compatible with the soliton lattice model, which was developed for one-dimensional case. In spite of higher dimensionality of CuO 2 layers the kink behavior of the electronic dispersion and flat bands near the saddle points find their essential explanation in the frame of this model. Recently measured de Haas–van Alphen values of electron and hole pockets in YBa 2Cu 3O 6.5 [1,2] are derived on the same basis. The similarities and fundamental differences from stripe models are discussed.
