A Geometric Approach to Strongly Correlated Bosons: From -Representability to the Generalized BEC Force
Chih-Chun Wang, Christian Schilling
Building on recent advances in reduced density matrix theory, we develop a geometric framework for describing strongly correlated lattice bosons. We first establish that translatio…
