Molecular Dynamics Study of 2-D Melting: Long Range Potentials
Melting of a two dimensional electron lattice and a two dimensional dipolar solid are studied using molecular dynamics technique. The existence of hysteresis and latent heat of melting are observed, and the melting transitions in the two cases are found to be first order. For an electron lattice the melting occurs between Γ=129±3 whereas in the dipolar solid it is between Γ=62±3, with a transition entropy of 0.3 kg per particle for both the systems.
