Long-lived universal resonant Bose gases

TL;DR

This paper proposes a method to create long-lived resonant Bose gases in two and three dimensions, overcoming atom loss issues and thermodynamical instability, with universal properties independent of short-range physics.

Contribution

It introduces a new approach to stabilize resonant Bose gases, enabling longer lifetimes and universal thermodynamical behavior in both 2D and 3D systems.

Findings

Lifetimes of resonant Bose gases can be significantly extended.

Thermodynamical properties are universal and independent of short-range physics.

Proposed systems suppress conventional few-body losses.

Abstract

Quantum simulations based on near-resonance Bose gases are limited by their short lifetimes due to severe atom losses. In addition to this, the recently predicted thermodynamical instability adds another constraint on accessing the resonant Bose gases. In this article, we offer a potential solution by proposing long-lived resonant Bose gases in both two and three dimensions, where the conventional few-body losses are strongly suppressed. We show that the thermodynamical properties as well as the lifetimes of these strongly interacting systems are universal, and independent of short-range physics.
