Spin wave theory for interacting hardcore bosons on cubic lattices: a comparative study
Vipin Kerala Varma, Hartmut Monien
Motivated by excellent comparisons of spin wave theory (SWT) with Quantum Monte Carlo (QMC) calculations of non-interacting hardore bosons (Bernardet et al.) and superlattices (Hen…

Lattice Green's functions for kagome, diced and hyperkagome lattices
Vipin Kerala Varma, Hartmut Monien
Lattice Green's functions (LGF) and density of states (DOS) for non-interacting models on 3 related lattices are presented. The DOS and LGF at the origin for the kagome and diced l…

Renormalization of two-body interactions due to higher-body interactions of lattice bosons
Vipin Kerala Varma, Hartmut Monien
We calculate thermodynamic properties of soft-core lattice bosons with on-site -body interactions using up to twelfth and tenth order strong coupling expansion in one and two di…
