Abstract

The Spectrum of the overlap Dirac operator in the deconfined phase of quenched gauge theory is known to have three parts: exact zeros arising from topology, small nonzero eigenvalues that result in a nonzero chiral condensate, and the dense bulk of the spectrum, which is separated from the small eigenvalues by a gap. In this paper, we focus on the,mail nonzero eigenvaluesin an SU(2) gauge field background at beta = 2.4 and N-T = 4. This low-lying spectrum is computed on four different Spatial lattices (12(3), 14(3), 16(3), and 18(3)). As the volume increases, the small eigenvalues become increasing concentrated near zero in such a way as to strongly suggest that the infinite volume condensate diverges.
