Reexamination of Finite-Lattice Extrapolation of Haldane Gaps
Hiroki Nakano, Akira Terai
We propose two methods of estimating a systematic error in extrapolation to the infinite-size limit in the study of measuring the Haldane gaps of the one-dimensional Heisenberg ant…
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…
Semi-Phenomenological Analysis of Dynamics of Nonlinear Excitations in One-Dimensional Electron-Phonon System
Makoto Kuwabara, Akira Terai, Yoshiyuki Ono
The structure of moving nonlinear excitations in one-dimensional electron-phonon systems is studied semi-phenomenologically by using an effective action in which the width of the n…
