    "abstract": "We study stability and structure of quark matters as a function of density in\na framework of molecular dynamics (MD). Using appropriate effective\ninteractions and the frictional cooling method, we search for the minimum\nenergy of the system. Transition from confined to deconfined phase is observed\nat densities of 2 -- 3$\\rho_0$, where $\\rho_0$ is the nuclear matter saturation\ndensity. The $uds$ matter becomes more stable than the charge-neutral $ud$\nmatter at 3$\\rho_0$, but the $udd$ matter is the most stable even at high\ndensity.",
