Possible explanation of the pseudogap in high-temperature cuprates
Journal Article

· Physical Review B
A concept describing the origin and some properties of the ''pseudogap phase'' of high-T{sub c} superconducting cuprates is proposed based on the author's idea about resonant tunneling connection between the CuO{sub 2} layers. The superconducting critical temperature in this picture is defined at low doping by establishment of a three-dimensional phase correlation between the layers, and at high doping by destruction of a d-wave superconductivity by disorder. The result is a nonmonotonic behavior of T{sub c} with doping. The pseudogap phase is analyzed qualitatively on the basis of the recently discovered existence of vortices in this phase and one-dimensional fluctuations due to extended saddle points (''hot spots'').
