Bipolarons high temperature superconductivity

All told, the theory makes predictions for weakly doped cuprates for temperatures up to Tc which are in remarkable agreement with experimentation. Our end result is that high temperature superconductivity is primarily an electron correlation effect possibly supplemented by longer range polaronic attraction of the type discussed by Mott and Alexandrov (see [8] for other references). Indeed, it can be argued that this is a theory of unbound bipolarons on a cuprate layer where the Fermion statistics are strictly maintained. 

Biopolymers, like nucleic acids (DNA and RNA), proteins, polysaccharides, lipids, and so on. have fundamental significance in life processes. Since the mid-1980s, highly conducting polymers, like doped different polyacetylenes (1) and (2) (SN) (3), or the TCNQ-TTF system (4) and (5), with quasi-one-dimensional alternating stacks of the two different types of molecule embedded in a three-dimensional molecular crystal, and PPV (6), have become objects of extensive experimental investigations because they are also candidates for the discovery of new physical phenomena, such as solitons, polarons and bipolarons, and superconductivity with higher transition temperatures (T ).
