Abstract
In this Brief Report, we present an algorithm for calculating the
elastic Lattice Greens Function of a regular lattice, in which
defects are created by removing lattice points. The method is
computationally efficient, since the required matrix operations are
on matrices that scale with the size of the defect subspace, and not
with the size of the full lattice. This method allows the treatment
of force fields with multi-atom interactions.
