Tapping the power of AI and high-performance computing to extend evolution to superconductors
Posted by Quinn Sena in categories: robotics/AI, supercomputing
Owners of thoroughbred stallions carefully breed prizewinning horses over generations to eke out fractions of a second in million-dollar races. Materials scientists have taken a page from that playbook, turning to the power of evolution and artificial selection to develop superconductors that can transmit electric current as efficiently as possible.
Perhaps counterintuitively, most applied superconductors can operate at high magnetic fields because they contain defects. The number, size, shape and position of the defects within a superconductor work together to enhance the electric current carrying capacity in the presence of a magnetic field. Too many defects, however, can lead to blocking the electric current pathway or a breakdown of the superconducting material, so scientists need to be selective in how they incorporate defects into a material.
In a new study from the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers used the power of artificial intelligence and high-performance supercomputers to introduce and assess the impact of different configurations of defects on the performance of a superconductor.

The first observation of the nuclear Barnett effect
Posted by Quinn Sena in categories: biotech/medical, neuroscience
The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular momentum of the electronic spins and the rotation of the rod.
Using a different method from that employed by Barnett, two researchers at NYU observed an alternative version of this effect called the nuclear Barnett effect, which results from the magnetization of protons rather than electrons. Their study, published in Physical Review Letters (PRL), led to the first experimental observation of this effect.
“I was a graduate student at NYU where a group of colleagues were involved in a project related to brain imaging,” Mohsen Arabgol, one of the researchers who carried out the study, told Phys.org. The fundamental idea behind the project was polarizing the brain molecules by inducing rotation using the Barnett effect and then applying the MRI-type imaging. I became interested and decided to work on the detection of the nuclear Barnett effect as my Ph.D. dissertation.”
