The random matrix model approach to quantum chromodynamics (QCD) with nonvanishing
chemical potential is reviewed. The general concept using global symmetries is introduced …

We investigate a new numerical procedure to compute fermionic correlation functions at very
small quark masses. Large statistical fluctuations, due to the presence of local``bumps''in the …

We present a lattice QCD determination of the chiral quark condensate based on a new
method. We extract the quark condensate from the operator product expansion of the quark …

In the epsilon-regime of QCD the main features of the spectrum of the low-lying eigenvalues
of the (euclidean) Dirac operator are expected to be described by a certain universality class …

We perform lattice simulations of two-flavor QCD using Neuberger's overlap fermion, with
which the exact chiral symmetry is realized at finite lattice spacings. The ϵ regime is reached …

We study various improved staggered quark Dirac operators on quenched gluon
backgrounds in lattice QCD generated using a Symanzik-improved gluon action. We find a …

The low-lying eigenvalue spectrum of the QCD Dirac operator in the ϵ regime is expected to
match with that of chiral random matrix theory (ChRMT). We study this correspondence for …

We investigate and clarify the role of topology and the issues surrounding the ε-regime for
staggered quarks. We study unimproved and improved staggered quark Dirac operators on …

We compute the condensate in QCD with two flavors of dynamical fermions using numerical
simulation. The simulations use overlap fermions, and the condensate is extracted by fitting …

No doubt, the lattice approach to quantum field theory has established itself as an integral
part of high energy theoretical physics and has produced many results that are relevant to …
