A generalized perspective on non-perturbative linked cluster expansions

K. Coester, S. Clever, F. Herbst +2

We identify a fundamental challenge for non-perturbative linked cluster expansions (NLCEs) resulting from the reduced symmetry on graphs, most importantly the breaking of translati…

Non-linear bond-operator theory and 1/d expansion for coupled-dimer magnets I: Paramagnetic phase

Darshan G. Joshi, Kris Coester, Kai P. Schmidt +1

For coupled-dimer Heisenberg magnets, a paradigm of magnetic quantum phase transitions, we develop a systematic expansion in 1/d, the inverse number of space dimensions. The expans…
