Query: An exact Polynomial Hybrid Monte Carlo algorithm for dynamical
  Kogut-Susskind fermions   We present a polynomial Hybrid Monte Carlo (PHMC) algorithm as an exact
simulation algorithm with dynamical Kogut-Susskind fermions. The algorithm uses
a Hermitian polynomial approximation for the fractional power of the KS fermion
matrix. The systematic error from the polynomial approximation is removed by
the Kennedy-Kuti noisy Metropolis test so that the algorithm becomes exact at a
finite molecular dynamics step size. We performed numerical tests with
$N_f$$=$2 case on several lattice sizes. We found that the PHMC algorithm works
on a moderately large lattice of $16^4$ at $\beta$$=$5.7, $m$$=$0.02
($m_{\mathrm{PS}}/m_{\mathrm{V}}$$\sim$0.69) with a reasonable computational
time.
