    "abstract": "Calculations of equilibrium properties of dense matter predict that at\nsubnuclear densities nuclei can be rodlike or slablike. To investigate whether\ntransitions between phases with non-spherical nuclei can occur during the\ncollapse of a star, we perform quantum molecular dynamic simulations of the\ncompression of dense matter. We have succeeded in simulating the transitions\nbetween rodlike and slablike nuclei and between slablike nuclei and cylindrical\nbubbles. Our results strongly suggest that non-spherical nuclei can be formed\nin the inner cores of collapsing stars.",
