Nonconservative dynamics in long atomic wires
Brian Cunningham, Tchavdar N. Todorov, Daniel Dundas
The effect of nonconservative current-induced forces on the ions in a defect-free metallic nanowire is investigated using both steady-state calculations and dynamical simulations.…
Current-induced forces: a simple derivation
Tchavdar N. Todorov, Daniel Dundas, Jing-Tao Lü +2
We revisit the problem of forces on atoms under current in nanoscale conductors. We derive and discuss the five principal kinds of force under steady-state conditions from a simple…
Current-induced atomic dynamics, instabilities, and Raman signals: Quasi-classical Langevin equation approach
Jing Tao Lü, Mads Brandbyge, Per Hedegård +2
We derive and employ a semi-classical Langevin equation obtained from path-integrals to describe the ionic dynamics of a molecular junction in the presence of electrical current. T…
