Abstract

We study finite-size scaling of the temperature zeroes of the partition function for Ф4 theory in four dimensions. The theory is simulated by Monte Carlo cluster methods and histograms are used to determine the partition function. The positions of the zeroes are obtained for lattices ranging from 84 to 244. The scaling laws include logarithmic corrections for the bulk quantities and we succeed to identify them clearly, in agreement with our analytical prediction.
