Tunable quantum criticality in multicomponent Rydberg arrays

Understand

Arrays of Rydberg atoms have appeared as a remarkably rich playground to study quantum phase transitions in one dimension.

• One of the biggest puzzles that was brought forward in this context are chiral phase transitions out of density waves.
• Theoretically predicted chiral transition out of period-four phase is still pending experimental verification mainly due to extremely short interval over which this transition is realized in a single-component Rydberg array.
• In this letter we show that multi-component Rydberg arrays with extra experimentally tunable parameters provide a mechanism to manipulate quantum critical properties without breaking translation symmetry explicitly.
