Analyzing the spectrum of general, non-hermitian Dirac operators
Christof Gattringer, Ivan Hip
We discuss the computational problems when analyzing general, non-hermitian matrices and in particular the un-modified Wilson lattice Dirac operator. We report on our experiences w…

Clover improvement, spectrum and Atiyah-Singer index theorem for the Dirac operator on the lattice
Christof Gattringer, Ivan Hip
We study the role of the O(a)-improving clover term for the spectrum of the lattice Dirac operator using cooled and thermalized SU(2) gauge field configurations. For cooled configu…
