An analysis of the T⊗(e+e) two-mode Jahn-Teller system with strong coupling

  • Published:
Il Nuovo Cimento D

Summary

Details of an approach for strongly coupled orbital triplet Jahn-Teller (JT) systems using a unitary transformation and energy minimization procedure are applied to the two-mode T⊗ (e+e) JT system in the case when both linear and quadratic coupling are included. The inclusion of quadratic JT coupling leads to a partial lift of degeneracy of the triplet ground states and the excited ones. The effect of static strains in strongly coupled T⊗ (e+e) JT system is also investigated analytically. We have shown that tetragonal trigonal and orthorhombic strains modify the structure of the system.
