Spin-wave excitation spectra and spectral weights in square lattice antiferromagnets
Rajiv R. P. Singh, Martin P. Gelfand
Using a recently developed method for calculating series expansions of the excitation spectra of quantum lattice models, we obtain the spin-wave spectra for square lattice, …

Series Expansions for Excited States of Quantum Lattice Models
Martin P. Gelfand
We show that by means of connected-graph expansions one can effectively generate exact high-order series expansions which are informative of low-lying excited states for quantum ma…

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…
