Spin-Wave Excitations of Half-Filled Kondo Lattice Model
Yasuhiro Matsushita, Ryousuke Shiina, Chikara Ishii
The spin excitations in the antiferromagnetic phase of half-filled Kondo lattice model are studied by means of the decoupling approximation for spin Green's function. The spin-wave…

Bond-Operator Mean Field Theory for the Bilayer Heisenberg Model
Yasuhiro Matsushita, Martin P. Gelfand, Chikara Ishii
Bond-operator mean field equations for the square-lattice, S=1/2 bilayer Heisenberg model are developed and solved numerically. In the vicinity of both the zero-field critical poin…
