Description
The canonical approach is one of the methods that have been pursued to solve the sign problem. However, this approach has the numerical instability, and most people have thought that this approach does not work for a long time.
We found that this instability can be solved by using the multiple precision computation. In this talk, we will study effects of the multiple precision computation and report some physical quantities in the finite density.
