"Generation, Detection and Application of Twisted Waves of Light and Neutrons"
It was about 50 years ago today, when "Dislocations in wave trains" came into play. Twenty years on, "Dislocations" became a nineties hit following the ingenious experiments of Soskin et al., that showed the promise of applications of twisted or structured light with non-vanishing orbital angular momentum about its propagation axis. Modern use cases for such modalities include increased communication bandwidth for 6G applications. Quantum particle beams can also be shaped by analogue tools of optics. I shall present recent results for neutrons, made possible by microfabricated synthetic holograms containing millions of forked dislocation gratings of the type envisaged by Soskin, et al.
The Institute for Physical Science and Technology (IPST) at the University of Maryland (UMD) invites outstanding young scientists to apply for the inaugural IPST Postdoctoral Fellowship in Artificial Chemical Intelligence.
The 26th annual Dr. Shih-I Pai Lecture took place on Tuesday, November 17th. Watch the video replay in case you missed it.
Chris Jarzynski (IPST/Chemistry and Biochemistry) with Mohammad Hafezi (ECE) and graduate student Alireza Seif, published an article in Nature Physics, September 21, entitled "Machine Learning the Thermodynamic Arrow of Time". The authors found that a machine learning algorithm that is trained to infer the direction of time’s arrow identifies entropy production as the relevant physical quantity in its decision-making process.
