Query: Development of the temperature-dependent interatomic potential for
  molecular dynamics simulation of metal irradiated with an ultrashort pulse
  laser   Laser ablation is often explained by a two-temperature model (TTM) with
different electron and lattice temperatures. To realize a classical molecular
dynamics simulation of the TTM, we propose an extension of the embedded atom
method to construct an interatomic potential that is dependent on the electron
temperature. This method is applied to copper, and its validity is demonstrated
by comparison of several physical properties, such as the energy-volume curve,
phonon dispersion, electronic heat capacity, ablation threshold, and mean
square displacement of atoms, with those of finite-temperature density
functional theory.
