The spin-phonon interaction in the spin-Peierls system introduces the spin frustration, which usually hinders the quantum Monte Carlo analysis, owing

The farther spin interactions than the nearest sites stem from a coupling with other degrees of freedom in many realistic materials. Among them, the spin-lattice interaction has a large contribution for the effective spin interaction, and the spin-P

There are three key points for the method to be effective: the choice of the ensemble, the selection of candidate configurations, and the determination of the transition probability (kernel). We focus our interest on the third optimization problem. After reviewing the p

Then, for overcoming the difficulty, we will apply the new Monte Carlo update techniques and the analysis that we developed in Chap. .–.. We will show the precise transition point and

The concept of the Peierls transition originates from the simple but drastic property about the instability to dimerization of the one-dimensional metal as early as 50’s. The lattice degree of freedom, there, was treated
