Description

Inspired by the narrow Feshbach resonance in systems with the two-body interaction, we propose a two-channel model of three-component fermions with a three-body interaction that takes into account finite-range effects in low dimensions. Within this model, the p-wave Efimov-like effect in the four-body sector is predicted in fractional dimensions between d=1 and d=2. The impact of the finite-range interaction on the formation of the four-body bound states in d=1 is also discussed in detail.
