## Abstract

In this thesis, we have developed the novel Monte Carlo methods and investigated precisely the critical phenomena of the spin-Peierls systems. The key theme is that the quantum lattice fluctuation introduces the spin frustration. 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 *adiabatically*; that is, it was approximated as a classical parameter.
