Researchers from LENS, CNR-INO, the University of Florence, UNAM, RPTU University Kaiserslautern-Landau, and TII Abu Dhabi have observed Shapiro steps in ultracold atoms for the first time. This allows for real-time observation of quantum mechanics and could lead to advanced quantum sensors and simulation. The experiments involved creating vortex-antivortex pairs, resulting in step-like signals, and the findings were published in Science. Why it matters: This breakthrough provides a new method to observe and control quantum coherence, potentially enabling advancements in quantum technologies and simulations within the region.
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.
KAUST's Visual Computing Center had two papers recognized at IEEE VIS 2023. One paper, from Prof. Markus Hadwiger's group, introduced a new method for detecting and visualizing vortex structures in 2D fluid flows, which was recognized as one of the best papers. The second paper, from Prof. Ivan Viola's team, presented Dr. KID, a visualization framework for physicalizing biological structures into 3D-printed models, receiving an honorable mention. Why it matters: These awards highlight KAUST's contributions to cutting-edge visualization techniques with potential applications in diverse scientific and engineering fields.
