Re-Structuring Method for the Negative Sign Problem in Quantum Spin Systems
Tomo Munehisa, Yasuko Munehisa
We present detailed discussions on a new approach we proposed in a previous paper to numerically study quantum spin systems. This method, which we will call re-structuring method h…

An Improvement on the Negative Sign Problem in Numerical Calculations of a Quantum Spin System
Tomo Munehisa, Yasuko Munehisa
We propose new approach to numerical study of quantum spin systems. Our method is based on a fact that one can use any set of states for the path integral as long as it is complete…
