Avoided level crossing spectroscopy with dressed matter waves

TL;DR

This paper introduces a method to detect and control resonances in macroscopic matter waves within shaken optical lattices by monitoring their response to parameter changes, revealing analogies with dressed atoms.

Contribution

The authors develop a novel spectroscopy technique for matter waves that allows probing and disabling resonances through specific driving amplitudes, highlighting new control possibilities.

Findings

Resonances can be detected via response to slow parameter changes.

Certain driving amplitudes can disable these resonances.

Analogies between dressed atoms and forced matter waves are established.

Abstract

We devise a method for probing resonances of macroscopic matter waves in shaken optical lattices by monitoring their response to slow parameter changes, and show that such resonances can be disabled by particular choices of the driving amplitude. The theoretical analysis of this scheme reveals far-reaching analogies between dressed atoms and time-periodically forced matter waves.
