Yang-Lee analysis of the grand canonical partition function for a Hubbard Model at finite doping is presented. Evaluating the zeros of this function in the complex chemical-potential plane, we observe an onset of a phase transition when the zeros approach the positive real half-axis with spatial increase of the simulated system. The peak of electronic susceptibility is located in the vicinity of the relevant zeros. © 1995.
