Phys. Rev. Lett. 82, 1474–1477 (1999)Vortex on the Surface of a Very Small Crystal during Martensitic TransformationReceived 2 November 1998; published in the issue dated 15 February 1999 Vortices of trajectories of atoms on the surface of a crystal are found as a transient pattern in the numerical experiment to study martensitic transformation in an ideal crystal which has its surface as a sole lattice defect, but no other internal lattice defect. An empirical instability condition for the appearance of the vortex is interpreted in terms of the dependence of the excitation energy of a vortex on its size. © 1999 The American Physical Society URL:
