  Single crystal Cu when shock loaded in certain direction for a certain narrow
range of piston velocities undergoes a structural phase transition from
face-centered cubic to different body-centered phases. Based on molecular
dynamic simulations, the manuscript identifies new phases of Cu through
detailed radial distribution function and x-ray diffraction analysis.
Identification of the new phases of Cu should initiate a re-evaluation of phase
diagram for Cu under high temperature and pressure conditions.
