  We study the dense nuclear matter within the holographic Sakai-Sugimoto
model. The nuclear matter is described via instantons in bulk, whose size has
the new temperature dependency. Then, properties of nuclear matter have been
studied for different temperatures. For example, free energy and baryon density
are examined for different temperature values. Also, nuclear matter properties,
like the speed of sound and connection of nuclear matter and quark matter, are
discussed. As we have increased the temperature, the phase transition value has
been changed from baryon to quark, which is non-physical. Also, we can see
continuity between the baryonic and quark phases. Speed of sound at the low
chemical potential in the presence of temperature is different, but when the
potential increases, the effect of temperature on the speed of sound will
remain unchanged. In the phase diagram, for significant chemical potential,
chiral symmetry is restored and provides all things that we have the realistic
model.
