Study shows polariton condensate can occupy two energy levels to form quantized vortex clusters

In a paper published in the Applied Physics Letters journal, a group of scientists demonstrated that under optical excitation, a polariton condensate can simultaneously occupy two closely spaced energy levels, which results in the formation of quantized vortex clusters. The outcomes of the study are prominent for optical tweezers, increasing the width of the data transmission channel in optical communication lines and other research areas.
