MD Simulation of Ionic Crystal under Strong Gravitational Field

Abstract:

Article Preview

Molecular dynamics (MD) simulations were performed to investigate unique crystalline states of typical ionic crystal at condition of a strong gravitational field (one million G). The simulation results showed that lattice vibration spectra of anion and cation along the gravity direction were different from the spectra along normal directions of the gravity. It is also shown that the shapes of spectra along the gravity are obviously different from the others along normal directions of the gravity. In addition, the peaks of spectra along the gravity were shifted. The simulation results showed that anisotropic lattice vibration spectra were induced by strong gravitational field, and it is insisted that the unique crystalline states and physical properties are induced by strong gravitational field.
