Query: Simple approach to current-induced effects -- bond weakening in metal
  chains   We present a simple, first principles scheme for calculating mechanical
properties of nonequilibrium bulk systems assuming an ideal ballistic
distribution function for the electronic states described by the external
voltage bias. This allows for fast calculations of estimates of the
current-induced stresses inside bulk systems carrying a ballistic current. The
stress is calculated using the Hellmann-Feynman theorem, and is in agreement
with the derivative of the nonequilibrium free energy. We illustrate the theory
and present results for one-dimensional (1D) metal chains. We find that the
susceptibility of the yield stress to the applied voltage agrees with the
ordering of break voltages among the metals found in experiments. In
particular, gold is seen to be the most stable under strong current, while
aluminum is the least stable.
