摘要:Overlap fermions are particularly well suited to study the finite temperature dynamics of the chiral
symmetry restoration transition of QCD, which might be just an analytic crossover. Using gauge
field configurations on a 243£10 lattice with Nf = 2 flavours of dynamicalWilson-clover quarks
generated by the DIK collaboration, we compute the lowest 50 eigenmodes of the overlap Dirac
operator and try to locate the transition by fermionic means. We analyse the spectral density, local
chirality and localisation properties of the low lying modes and illustrate the changing topological
and (anti-) selfdual structure of the underlying gauge fields across the transition.
