Description:
Author(s): Shivam Ghosh, Hitesh J. Changlani, and Christopher L. Henley Using an adaptation of Schwinger boson mean field theory (SBMFT) for nonuniform systems, we study the nature of low-energy spin excitations on the square and Bethe lattices at their percolation threshold. The optimal SBMFT parameters are interpreted as on-site potentials and pairing amplitudes, whic… [Phys. Rev. B 92, 064401] Published Mon Aug 03, 2015
