Efforts to duplicate on Earth the fusion reactions that power the sun and stars for unlimited energy must contend with extreme heat-load density that can damage the doughnut-shaped fusion facilities called tokamaks, the most widely used laboratory facilities that house fusion reactions, and shut them down. These loads flow against the walls of what are called divertor plates that extract waste heat from the tokamaks.

Home > Press > Quantum quirk yields giant magnetic effect, where none should exist: Study opens window into the landscape of extreme topological matter
Rice University theoretical physicists (from left) Hsin-Hua Lai, Qimiao Si and Sarah Grefe worked with experimental collaborators at Vienna University of Technology to understand topological features of a nonmagnetic Weyl-Kondo semimetal allowed it to produce a giant Hall effect in the absence of a magnetic field.

Abstract:
In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect a characteristic change in the way electricity is conducted in the presence of a magnetic field in a nonmagnetic quantum material to which no magnetic field was applied.
The Entangled Dance of Atom Beams

Physically distant quantum particles can share properties and can behave as a single object. For pairs of photons, this entangled behavior allows for data transfer between the two particles, for example. Quantum entanglement can also occur between more massive particles, including two individual atoms. Now, in a controlled experiment, Filippo Borselli of the Vienna University of Technology, Austria, and colleagues create traveling beams of entangled atoms that are reliably produced from a reservoir source using two parallel waveguides [1]. The experiment could be a starting point for developing integrated quantum circuits and quantum-information processing devices that use pairs of atoms.
Austrian regulator says cryptocurrency is associated with 60% of financial fraud cases
The Austrian Financial Market Authority (FMA) stated on Friday that crimes involving the use of cryptocurrencies have increased across the country. According to the report, more than 60% of all reported financial fraud cases involve crypto trading products. The agency calls for urgent and stricter supervision.
The FMA report stated that two-thirds of investment fraud reports submitted in 2020 are related to cryptocurrency and digital foreign exchange trading products. FMA also claims that these crypto scammers are using social media platforms such as Telegram and TikTok to find victims to carry out fraud.
