A theoretical scenario used for achieving efficient field-free molecular orientation with a few half-cycle pulses (HCPs) is proposed,with the LiH molecule as an
Diffusion of Cu hexamer islands on Cu(111) and Ag(111) is studied using a molecular dynamics simulation technique with many-body potentials obtained from the em
Natural and chaotic time series are predicted using an artificial neural network (ANN) based on particle swarm optimization (PSO).Firstly,the hybrid ANN+PSO alg
