Manifestations of quasi-one-dimensional correlations in the electronic properties of transition-metal oxides
As follows from the string model, the pseudogap anomalies in the electronic properties of lightly doped cuprates, observed by different methods, can be explained by the segregation of charge carriers into bosonic stripes. The comparative investigation of the similar anomalies revealed in several “copperless” transition-metal oxides reliably suggests that these anomalies are likely to be due to the analogous processes of quasione-dimensional structurization of paired charge carriers into a metastable network of conducting nanochannels.
