Diagonal hopping by electrons explains superconductivity in cuprate ‘high-temperature’ superconductors, according to researchers associated with the Flatiron Institute in New York. The team used a straightforward two dimensional model, the Hubbard model, and hundreds of hours of supercomputer effort to get results that are close to those found in experiments. “There was tremendous excitement when cuprate superconductors were discovered, but no understanding of why they remain superconductive at such high temperatures,” said Flatiron scientist Shiwei Zhang.
4. US slaps 100% tariff on China EVs and 50% tariff on China chips
US president Joe Biden has imposed a 100% tariff on Chinese EVs imported into the US and a 50% tariff on semiconductors. Both tariffs are in response to an anticipated flood of cheap EVs and chips. “We know the PRC’s playbook and cannot allow China to undermine U.S. supply chains by floodingIMG_0412-150×150.jpeg the market with artificially cheap products that hurt American businesses and workers,” says US Secretary for Commerce Gina Raimondo.
3. Quantum navigation components demonstrated in flight
A consortium has demonstrated quantum-based inertial navigation in an aircraft, the first such demonstration to be made public, according to the UK Government’s Department for Science, Innovation and Technology (DSIT). By using quantum-based references in the accelerometers and gyros at the heart of an intertial measurement unit (IMU), it is theoretically possible to maintain absolute accuracy over time as an object moves from its initial location – removing the drifty nature of normal accelerometers and gyros.
2. Glasgow University gets £3m grant for IC packaging research
Glasgow University has received a £3 million grant to build research facilities for IC integration and packaging. The EPSRC’s Strategic Equipment Grant scheme will provide £3m to help the University establish ANALOGUE – the Automated Nano AnaLysing, characterisatiOn and additive packaGing sUitE. New developments prototyped at ANALOGUE could find applications in biomedical implants, sustainable and biodegradable sensors, and quantum computing interfaces.
1. Raspberry Pi to float this month
Raspberry Pi could IPO in the next ten days, reports the Times. In its last reported results filing – for 2022 – the company had revenues of £187 million for a profit of £20 million. It is reported that the company will be looking for a valuation of up to £500 million. The company raised funds last year at a valuation of £447 million. CM4 Raspberry Pi Compute Module 4 CM4It is said that part of Raspberry Pi’s current pitch to investors is that it can sell more product to businesses and internationally. Arm and Sony are both investors in Raspberry Pi.
