Description
We investigate the phase structure and the equation of state (EoS) for dense two-color QCD at low temperatures using the lattice Monte Carlo simulations. A rich phase structure below the pseudo-critical temperature $T_c$ as a function of quark chemical potential $\mu$ has been revealed. In high density regime, we can see a superfluid phase, where the diquark condensate takes non-zero expectation value. We newly found that the speed of sound exceeds the conformal bound, $c_{\mathrm s}^2/c^2 = 1/3$, which is the value of relativistic free theory.
