We introduce an ab initio molecular-dynamics method based on the discretized path-integral representation of quantum particles. Fermi statistics is automatically generated by an effective exchange potential. This path-integral molecular-dynamics method is able to stimulate electron plasmas at the border of the degenerate and the semidegenerate regimes with a satisfactory level of accuracy. Application of the method to the simulation of a liquid alkali metal demonstrates its potential in the simulation of real systems from first principles.
