Frustrated quantum-spin system on a triangle coupled with $e_{g}$ lattice vibrations - Correspondence to Longuet-Higgins et al.'s Jahn-Teller model -

Hisatsugu Yamasaki, Yuhei Natsume, Akira Terai +1

We investigate the quantum three spin model $(S_{1}, S_{2}, S_{3})$ of spin $= 1/2$ on a triangle, in which spins are coupled with lattice-vibrational modes through the exc…

Chaos-induced breaking of the Franck-Condon approximation

Hisatsugu Yamasaki, Yuhei Natsume, Akira Terai +1

We investigate the vibrational structure of electronic spectra for the transition from the non-degenerate $A$ state to $E$ states in $E_{g} \otimes e_{g}$ Jahn-Teller systems with the t…
