• Core structure of screw dislocations in body-centred cubic metals: relation to symmetry and interatomic bonding (2004, methodology): “…Mrovec 2002) and most recently by ab-initio density functional theory (DFT)-based methods (IsmailBeigi and Arias 2000, Woodward and Rao 2001, 2002, Frederiksen and Jacobsen 2003), all revealed nonplanar cores and the twinning–antitwinning asymmetry of the critical stress at which the dislocation…”
• Core structure and Peierls potential of screw dislocations in α-Fe from first principles: cluster versus dipole approaches (2007, background): “The first one corresponds to a triangular periodic array of dislocation dipoles in which the dislocations are positioned on a honeycomb network that preserves the three-fold symmetry of the bcc lattice in the 〈111〉 direction [5] (Fig.”
