概要
- 論文の詳細を見る
The thermodynamics of dissipative quantum systems with double-well potentials is studied by a path-integral Monte Carlo (PIMC) method without truncation to the two-state model. For efficient simulation at low temperatures, we develop a new local update scheme on the basis of the approximate decomposition of the Boltzmann weight to Gaussian distributions. The localization transition induced by ohmic dissipation is clarified numerically for arbitrary potential barriers.
