Аннотация:
Electrons (or holes) added to a commensurate charge-density-wave insulator can bind to form bi-polaron states. Bose condensation of these bi-polarons may occur at relatively high temperatures. This mechanism may be relevant for the recently discovered high-T<sub>c</sub> superconductors La<sub>2-x</sub>Sr<sub>x</sub>CuO<sub>4</sub>.
