Direct calculation of the spin stiffness on square, triangular and cubic lattices using the coupled cluster method

S. E. Krüger, R. Darradi, J. Richter +1

We present a method for the direct calculation of the spin stiffness by means of the coupled cluster method. For the spin-half Heisenberg antiferromagnet on the square, the triangu…
