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.
A DeepMind researcher presented work on incorporating symmetries into machine learning models, with applications to lattice-QCD and molecular dynamics. The work includes permutation and translation-invariant normalizing flows for free-energy estimation in molecular dynamics. They also presented U(N) and SU(N) Gauge-equivariant normalizing flows for pure Gauge simulations and its extensions to incorporate fermions in lattice-QCD. Why it matters: Applying symmetry principles to generative models could improve AI's ability to model complex physical systems relevant to materials science and other fields in the region.
KAUST researchers have published a review paper in Science magazine covering memristor technology, comparing it to the original transistor. Dr. Mario Lanza is the lead author of the paper, which summarizes data supporting memristor technology readiness across materials and applications. The paper statistically shows the technical criteria for how memristors function in various configurations. Why it matters: Memristors could become the new switching technology standard, surpassing transistors in speed and operational efficiency, especially as current chip technology reaches its quantum limit in terms of size.
This article summarizes presentations from an internal Quantum Research Center (QRC) workshop at the Technology Innovation Institute (TII). Topics covered included superconducting quantum computers, quantum coherent networks, quantum simulation, and quantum machine learning. Several presentations also discussed experimental quantum technologies. Why it matters: The workshop highlights TII's ongoing research activities in quantum computing and related technologies, signaling its commitment to advancing the field in the UAE.
KAUST held a research conference on Synergistic Approaches in Solar Energy Conversion from February 25-27, bringing together KAUST researchers and international colleagues. The conference, organized by the KAUST Solar Center (KSC), focused on performance-limiting factors, emerging synergistic approaches, and methods to overcome current performance limits in solar energy. Yves Gnanou and Professor Iain McCulloch highlighted KAUST's commitment to solar energy research and the KSC's role in collaborative, applied solutions. Why it matters: The conference underscores KAUST's dedication to advancing solar energy technologies and fostering international collaboration to address regional and global energy challenges.
William Tang from Princeton spoke at KAUST about using deep learning to achieve nuclear fusion. Nuclear fusion, recreating stellar conditions on Earth, is considered the "holy grail" of power sources because it is clean and does not produce radioactive waste. Tokamaks, invented by Soviet physicists, are devices used to contain plasma, the superheated ionized gas required for fusion. Why it matters: KAUST is contributing to research on sustainable energy solutions, including exploring the potential of AI in nuclear fusion, a potentially transformative clean energy source.
A KAUST article discusses the future of energy, highlighting the role of hydrocarbon fuels and the need for sustainable practices. Professor Tadeusz W. Patzek's paper emphasizes finding sustainable bridges until alternative energy sources become viable. The article contrasts optimistic and pessimistic views on energy sustainability, drawing parallels to the whale oil industry. Why it matters: The piece highlights the tension between continued reliance on fossil fuels and the urgent need for alternative energy sources and reduced consumption in the GCC region and globally.
