摘要：We study the location of the partition function zeros in the complex b plane (Fisher’s Zeros) for SU(2) lattice gauge theory on L4 lattices. We discuss recent attempts to locate complex zeros for L = 4 and 6. We compare results obtained using various polynomial approximations of the logarithm of the density of states and a straightforwardMC reweighting. We conclude that the method based on a combination of discrete Chebyshev orthogonality and patching plaquette distributions at different b provides the more reliable estimates.
