Abstract

Molecular dynamics simulations for nucleon many-body systems is briefly introduced. We employ quantum molecular dynamics (QMD) to investigate nuclear reactions with incident energy of a few to several hundred MeV/nucleon and also the ground state structures of nuclear matter. To use QMD model for such low-energy phenomena, improvement and refinement are necessary for several points such as inclusion of Pauli potential and taking care of the spurious zero-point energy of clusters. On the other hand, we have proposed a new application of MD to the quark system. Though there are many rooms of improvements, our MD for quark system shows some interesting results. In this review article, reported are the frameworks and the results already published by the author and his collaborators. However, it should be worth reviewing our works on MD, since it will be found that the similar frameworks can be applied to various subjects in the field of nuclear physics.
