- Authors: V. Polkanov and V. Pastukhov
- Abstract summary: We propose the two-channel model of three-component fermions with the three-body interaction.
The $p$-wave Efimov-like effect in the four-body sector is predicted in fractional dimensions above 1D.
The impact of the finite-range interaction on the formation of the four-body bound states in $d=1$ is also discussed in detail.

- Abstract: Inspired by the narrow Feshbach resonance in systems with the two-body
interaction, we propose the two-channel model of three-component fermions with
the three-body interaction that takes into account the 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 above 1D. The impact of
the finite-range interaction on the formation of the four-body bound states in
$d=1$ is also discussed in detail.

We show that in the limit one obtains the one-body Hamiltonian for the light particle subject to $N$ (non-local) point interactions placed at fixed positions.
We will verify that such non-local point interactions do not exhibit the ultraviolet pathologies that are present in the case of standard local point interactions.

We propose an interferometric setting through which N-particle interference can be observed, while any interference of lower orders is strictly suppressed.
We experimentally demonstrate this effect in a four-photon interferometer, where the interference is nonlocal, in principle.
A joint detection of all four photons identifies a high-visibility interference pattern varying as a function of their collective four-particle phase, a genuine four-body property.

A four-boson limit-cycle independent of the Efimov one appears in Hamiltonian systems at the unitary limit.
This is a universal manifestation of an independent four-boson scale associated with a cycle beyond the Efimov one.

Because of this three-body coupling, the three-body contact characterizing a local correlation appears in the energy relation for fermions.
