Symmetry considerations in exact diagonalization: spin-1/2 pyrochlore magnets

Strongly Correlated Electrons 2025-04-14 v1

Abstract

We describe how the methods of group theory (symmetry) are used to optimize the problem of exact diagonalization of a quantum system on a 16-site pyrochlore lattice. By analytically constructing a complete set of symmetrized states, we completely block-diagonalize the Hamiltonian. As an example, we consider a spin-1/2 system with nearest neighbour exchange interactions.
