Baker-Campbell-Hausdorff expansion in creation-only coupled cluster

Chemical Physics 2025-11-11 v1

Abstract

We study the properties of the exponential ansatz formed by strings of creation operators. We discuss the conditions under which we can recover a structure similar to traditional coupled cluster methods. We pay particular attention to the Baker-Campbell-Hausdorff expansion of these operators.
