Abstract: The role of phase-space occupation effects for the formation of two- and three-particle bound states in a dense medium is investigated for systems with short-range interactions. While for two-fermion bound states due to the Pauli blocking in a dense medium the binding energy is reduced and vanishes at a critical density (Mott effect), for three-fermion bound states, it is shown to be nonzero and positive. Therefore, beyond the Mott density of the two-fermion bound state, three-fermion bound states can exist in a medium and, therefore, be denoted as the in-medium Borromean states.
