Seeking better times: atomic clocks in the generalized Tonks-Girardeau regime

TL;DR

This paper explores the potential of using generalized Tonks-Girardeau gases of strongly interacting cold atoms in atomic clocks, aiming to improve timekeeping precision through novel quantum regimes.

Contribution

It introduces a generalized model of Tonks-Girardeau gases for two-level atoms and examines their application in Ramsey interferometry for atomic clocks.

Findings

Generalized TG gases can be integrated with Ramsey interferometry.

Potential for enhanced precision in atomic clocks using TG gases.

Provides theoretical framework for future experimental studies.

Abstract

This article is based on the talk with the same title at the Blaubeuren meeting. First we discuss briefly the importance of time and time keeping, explaining the basic functioning of clocks in general and atomic clocks in particular, which rely on Ramsey interferometry. The usefulness of cold atoms is discussed as well as their limits in Bose-Einstein condensates. An alternative that we study is a different cold-atom regime: the Tonks-Girardeau (TG) gas of tightly confined and strongly interacting bosons. The TG gas is reviewed and then generalized for two-level atoms. Finally, we explore the combination of Ramsey interferometry and TG gases.
