Frustrated quantum-spin system on a triangle coupled with 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 of spin 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 state to states in Jahn-Teller systems with the t…

Chaos and its quantization in dynamical Jahn-Teller systems
Hisatsugu Yamasaki, Yuhei Natsume, Akira Terai +1
We investigate the Jahn-Teller system for the purpose to reveal the nature of quantum chaos in crystals. This system simulates the interaction between the nuclear…
