  We utilized the AMPT model to simulate the shear viscous transport dynamics
of parton matter in Au+Au collisions at a constant specific shear viscosity and
varying phase transition temperatures at 200 GeV. The resulting charged hadron
spectra and anisotropic flow profiles correspond closely with experimental
data. The transverse momentum spectra and longitudinal decorrelations are
essentially unaffected by the phase transition temperature. An increase in the
phase transition temperature leads to a rise in particle yields at midrapidity,
accompanied by a decrease in both elliptic and triangular flows over a range of
transverse momenta and pseudorapidities.
