Jahn - Teller Effect in Diamond - like Carbon
The Jahn-Teller effect used semi-theoretically to analyse UV-visible spectra of the diamond like-carbon films on Si substrates. By deconvolution of UV-visible absorption spectra of the typical films, different absorption lines found. For each sample, six lines which were related to V • by Jahn-Teller effect are distinguished. Our theoretical approach based on distortion of the V • as the conseq...
متن کاملmodes dynamic Jahn - Teller systems at strong coupling
We find the exact semiclassical (strong coupling) zero-point energy shifts applicable to the e⊗ (n E) and t⊗ (n H) dynamic Jahn-Teller problems, for an arbitrary number n of discrete vibrational modes simultaneously coupled to one single electronic level. We also obtain an analytical formula for the frequency of the resulting normal modes, which has an attractive and apparently general Slater-K...
متن کاملSpin-orbit coupling and the Jahn-Teller effect: vibronic and spin-vibronic angular momenta
The concept of symmetry and its breaking holds a special and important place in the physical sciences. One of the best known examples of such symmetry breaking is the Jahn-Teller effect. In their original paper, Jahn and Teller demonstrated(Jahn & Teller 1937) that a symmetry-dictated electronic degeneracy will always be raised by a non-totally symmetric distortion linear in nuclear coordinates...
متن کاملJahn-Teller effect in the augmented Hubbard model
We investigate the effects induced by the interplay of microscopic degrees of freedom. In many cases, one has to consider spin and orbital degeneracy to explain complex structures of magnetic and orbital order. Frequently, attention is focused on electronic correlations. We study how the interaction of electrons with lattice degrees of freedom modifies the pure electronic case. Because of orbit...
متن کاملJahn-Teller effect in trigonal symmetry : 3dn ions in corundum
2014 The theory of the Jahn-Teller effect is treated for the case of trigonal symmetry and strong vibronic interaction. The vibronic Hamiltonian is established assuming that the vibrational modes are any E modes whatsoever but respecting the trigonal symmetry. The trigonal potential and the vibronic interaction are diagonalized at the same time, in the basis of the cubic T1 or T2 electronic sta...
