An inversion-relaxation approach for sampling stationary points of spin model Hamiltonians

JOURNAL OF CHEMICAL PHYSICS, 140(19).

By: C. Hughes*, D. Mehta n & D. Wales*

TL;DR: This work introduces a sampling method based on relaxation from stationary points of the highest index of the Hessian matrix that can find all the stationary points for potentials or Hamiltonians bounded from above, and shows that it is far more efficient than previous methods.
