Description

In this talk, we study a bottom-up holographic model where nuclear matter is realized as a dilute gas of deformed instantons in six dimensions. In the probe approximation, we obtain a stiff equation of state for the nuclear matter, where the speed of sound is relatively large. Based on the above observation, Tolman-Oppenheimer-Volkov (TOV) equation is solved numerically and then we find the mass-radius (M-R) relation, which is similar to that of quark matter. This is a result specific to our holographic model.
