Technology Innovation Institute Discovers Key Element in Developing Quantum Sensors

Summary

Researchers at Abu Dhabi’s Technology Innovation Institute (TII) have identified a new universality in dynamic phase transitions by investigating a "quench" scenario in a two-dimensional atomic cloud undergoing a Kosterlitz-Thouless (BKT) transition. They discovered the universal behavior that vortex pairs form from the fluctuations of the atomic cloud during this dynamic phase transition and successfully described the process using a real-time renormalization method. Their paper, titled “Universal scaling of the dynamic BKT transition in quenched 2D Bose gases”, was published in Science. Why it matters: This discovery could catalyze the development of sensitive quantum sensors and contributes to a better understanding of many-body dynamics.
