# Width of the confinement-induced resonance in a quasi-one-dimensional trap with transverse anisotropy

## TL;DR

This paper investigates how the width of the s-wave confinement-induced resonance in quasi-one-dimensional atomic gases can be controlled by transverse anisotropy, with implications for experimental probing of interaction energies.

## Contribution

It provides a theoretical analysis showing that transverse anisotropy can tune the CIR width, a novel insight for controlling atomic interactions in quasi-1D systems.

## Key findings

- CIR width is tunable via transverse anisotropy.
- Changes in CIR width affect the interaction energy discontinuity.
- Theoretical predictions can be tested experimentally.

## Abstract

We theoretically study the width of the s-wave confinement-induced resonance (CIR) in quasi-one-dimensional atomic gases under tunable transversely anisotropic confinement. We find that the width of the CIR can be tuned by varying the transverse anisotropy. The change in the width of the CIR can manifest itself in the position of the discontinuity in the interaction energy density, which can be probed experimentally.
