Query: QCD phase diagram at strong coupling including auxiliary field
  fluctuations   We investigate the phase diagram and the mechanism for the sign problem to
appear in finite density QCD at strong coupling in a combined framework of the
auxiliary field Monte-Carlo (AFMC) and the chiral angle fixing (CAF) methods.
When bosonizing meson hopping terms in the effective action, we need to
introduce imaginary number coefficients, which leads to a complex phase in
numerical simulations. By using the cut-off technique, we quantitatively show
that high momentum modes of auxiliary fields mainly contribute to the weight
cancellation; Cutting-off high-momentum auxiliary field modes does not modify
order parameters but suppresses statistical weight cancellation, when we choose
the cut-off parameter appropriately.
