Interlayer Coupling in Magnetic/Pd Multilayers
Zhu-Pei Shi, Barry M. Klein
The Anderson model of local-state conduction electron mixing is applied to the p roblem of interlayer magnetic coupling in metallic multilayered structures with palladium (Pd) spac…
The Spin Stiffness and the Transverse Susceptibility of the Half-filled Hubbard Model
Zhu-Pei Shi, Rajiv R. P. Singh
The spin stiffness and the transverse susceptibility of the square lattice half-filled Hubbard model are calculated as a function of the Hubbard paramete…
Ising Expansion for the Hubbard Model
Zhu-Pei Shi, Rajiv R. P. Singh
We develop series expansions for the ground state properties of the Hubbard model, by introducing an Ising anisotropy into the Hamiltonian. For the two-dimensional (2D) square latt…
ELECTRONIC STRUCTURE OF FeSi
V. R. Galakhov, E. Z. Kurmaev, V. M. Cherkashenko +8
The full set of high-energy spectroscopy measurements including X-ray photoelectron valence band spectra and soft X-ray emission valence band spectra of both components of FeSi (Fe…
Phase Transitions in the Symmetric Kondo Lattice Model in Two and Three Dimensions
Zhu-Pei Shi, Rajiv R. P. Singh, Martin P. Gelfand +1
We present an application of high-order series expansion in the coupling constants for the ground state properties of correlated lattice fermion systems. Expansions have been gener…
