Query: Ab initio study of QCD thermodynamics on the lattice at zero and finite
  densities   The WHOT-QCD Collaboration is pushing forward a series of lattice studies of
QCD at finite temperatures and densities using improved Wilson quarks. Because
Wilson-type quarks require more computational resources than the more widely
adopted staggered-type quarks, various theoretical and computational techniques
have to be developed and applied. In this paper, we introduce the fixed-scale
approach armed with the T-integration method, the Gaussian method based on the
cumulant expansion, and the histogram method combined with the reweighting
technique. Adopting these methods, we have carried out the first study of
finite-density QCD with Wilson-type quarks and the first calculation of the
equation of state with 2+1 flavors of Wilson-type quarks. We present results of
these studies and discuss perspectives towards a clarification of the
properties of 2+1 flavor QCD at the physical point, at finite temperatures and
densities.
