| Research Abstract |
We developed a new method to calculate physical quantity in the quantum spin system. This method is one of first principle methods and called as a stochastic state selection method. By this method we can calculate energy and other quantity in triangular lattice. In this system our results indicate that the spontaneous symmetry breaking occurs and the Nambu boson exists.
