| Popis: | A universal approach is proposed to study the influence of strain (pressure) on the temperature of Bose–Einstein condensation of intersite bipolarons within the extended Holstein model. It is shown that uniaxial strain (pressure) derivatives of the temperature of such a Bose–Einstein condensation strongly depend on the arrangement of ions in the lattice. In particular, they may be positive or negative. A connection between the theoretically obtained results, along with the experimental data, on the influence of uniaxial pressure (strain) on Tc of RBa 2 Cu 3 O 7 − δ family cuprates is discussed. |
