Chemical potential for harmonically interacting particles in a harmonic potential

Philip Phillips, Ernest R. Davidson

Research output: Contribution to journalArticle


The chemical potential μ, as it appears in density functional theory, is examined extensively for harmonically interacting spin‐½ fermions in three dimensions. For this system the energy and chemical potential are discontinuous functions of the particle number if the most straightforward equation is used to define the energy for a noninteger particle number.
