We demonstrate that scattering of particles strongly interacting in three dimensions (3D) can be suppressed at low energies in a quasi-one-dimensional (1D) confinement. The underlying mechanism is the interference of the s- and p-wave scattering contributions with large s- and p-wave 3D scattering lengths being a necessary prerequisite. This low-dimensional quantum scattering effect might be useful in "interacting" quasi-1D ultracold atomic gases, guided atom interferometry, and impurity…

We observe and analyze d-wave resonant scattering of bosons in tightly confining harmonic waveguides. It is shown that the d-wave resonance emerges in the quasi-1D regime as an imprint of a 3D d-wave

A nonperturbative theoretical framework to treat collisions with generic anisotropic interactions in quasi-one-dimensional geometries and predicts dipolar confinement-induced resonances (DCIRs) which are attributed to different angular momentum states.

Landau quantization effects in ultracold atom–ion collisions

We study ultracold atom–ion collisions in the presence of an external magnetic field. At low collision energy the field can drastically modify the translational motion of the ion, which follows

Quantum scattering in quasi-one-dimensional cylindrical confinement (15 pages)

Finite-size effects not only alter the energy levels of small systems, but can also lead to additional effective interactions within these systems. Here the problem of low-energy quantum scattering

Tuning the interactions of spin-polarized fermions using quasi-one-dimensional confinement.

A multichannel scattering theory for atom-atom collisions in quasi-1D geometries is developed and it is shown that tightly confined fermions have infinitely strong interactions at a particular value of the 3D, free-space p-wave scattering volume.

A spin-polarized degenerate Fermi gas interacting via a p-wave Feshbach resonance in an optical lattice is studied to realize one- and two-dimensional gases and, therefore, to restrict the asymptotic scattering states of atomic collisions.
