“…The occurrence of small polarons in high-T, superconducting materials such as La-Ba-Cu-0 or Y-Ba-Cu-0 has been reported recently [8]. In the localized limits these polarons are envisaged as excess charge carriers centred at Cu ions in central-cage ab-planes.…”

Sm, Eu, and La) are investigated in the orthorhombic (HTC) and tetragonal (non-HTC) phases using EPR method. For both phases EPR signals associated with G d ions are detected. In the tetragonal phase a strong temperature dependence of the intensities of this line is observed. These characteristics can be ascribed to the skin effect. A small polaron model is proposed to interpret the conduction mechanism of the tetragonal phase (semiconducting) of these samples.Mittel EPR werden die Materialien Gd,,,Re,,,Ba,Cu30,-, (Re = Y, Sm, En und La) in der rhombischen (HTC) und tetragonalen (Nicht-HTC)-Phase untersucht. Fur beide Phasen werden mit Gd-Ionen verbundene Signale nachgewiesen. In der tetragonalen Phase wird eine starke Temperaturabhangigkeit der Intensitat dieser Linie beobachtet. Diese Charakteristiken lassen sich dem Skin-Effekt zuschreiben. Ein Model1 kleiner Polaronen wird vorgeschlagen, um den Leitungsmechanismus der tetragonalen Phase (halbleitend) dieser Proben zu interpretieren.

“…Physically this may occur in a system that has a foreign ion embedded in either a trigonal or hexagonal host (i.e., AgCl:Fe 2+ ). More recently, the Jahn–Teller effect has been mentioned as a possible mechanism for high‐temperature superconductivity 9–12.…”

“…Because of the relative simplicity of the model, and because a complete numerical solution to the linear E ⊗ ε system has been known for a long time 5, theorists have had at their disposal an excellent proving ground for a variety of calculational efforts 7–14. Of most interest to our work here is the coupled‐cluster method (CCM) of Wong and Lo 15.…”

“…Further interest in certain aspects of the Jahn-Teller effect has come to the fore as a possible physical mechanism for high-temperature superconductors. [12][13][14][15] A complete numerical solution of the linear E ⑀ system has been known for a number of years. 5 However, interest in analytic methods applied to this system has not waned.…”

Linear Jahn-Teller effect: A connected-moments approach

The ground-state energy of the linear E ⑀ Jahn-Teller effect is obtained using a connected-moments expansion. The calculation is straightforward and leads to a set of simple algebraic expressions for the connected moments of the Hamiltonian. This is then compared to a recent calculation wherein a coupled-cluster scheme has been applied resulting in a set of thirteen nonlinear coupled algebraic equations.
