摘要：

Two distinct energy scales, the d-wave superconducting order parameter, and the charge segregation in the form of stripes in cuprates are unified in the framework of the bipolaron theory as a result of the formation of mobile bipolarons in the normal state and their Bose-Einstein condensation. Within the theory both the d-wave superconducting order parameter and striped charge distribution result from the bipolaran (center-of-mass) energy band dispersion rather than from any particular interaction.
