Science Daily February 15, 2024 Arrays of Rydberg atoms are suitable to study quantum phase transitions in one dimension. 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. Researchers in the Netherlands showed that multicomponent Rydberg arrays with extra experimentally tunable parameters provided a mechanism to manipulate quantum critical properties without breaking translation symmetry explicitly. They considered an effective blockade model of two component Rydberg atoms. Weak and strong components obeyed nearest- and next-nearest-neighbor blockades correspondingly. When laser detuning […]
