The canonical approach, which was developed for solving the sign problem, may suffer from a new type of sign problem. In this method, the grand partition function is written as a fugacity expansion:, whereis the fugacity, andare given as averages over a Monte Carlo update,. We show that the complex phase ofis proportional toat each Monte Carlo step. Althoughtake real positive values, the values offluctuate rapidly whenis large, especially in the confinement phase, which gives a limit on. We discuss a mechanism of phase emergence.
