Phys. Rev. Lett. 97, 021101 (2006) [4 pages]Calculation of the First Nonlinear Contribution to the General-Relativistic Spin-Spin Interaction for Binary SystemsReceived 25 April 2006; published 13 July 2006 We use recently developed effective field theory techniques to calculate the third order post-Newtonian correction to the spin-spin potential between two spinning objects. This correction represents the first contribution to the spin-spin interaction due to the nonlinear nature of general relativity and will play an important role in forthcoming gravity wave experiments. © 2006 The American Physical Society URL:
