Hot topic – how heat flow affects the Earth’s magnetic field

The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth’s core, where temperatures exceed 5,000-degress C. New research from geophysicists at the University of Leeds suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities – or anomalies, as scientists call them – of the Earth’s magnetic field.

Key witness helps scientists detect ‘spooky’ quantum entanglement in solid materials

Quantum entanglement occurs when two particles appear to communicate without a physical connection, a phenomenon Albert Einstein famously called “spooky action at a distance.” Nearly 90 years later, a team led by the U.S. Department of Energy’s Oak Ridge National Laboratory demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material.

Quantum Computing Enables Unprecedented Materials Science Simulations

Researchers have for the first time used a quantum computer to generate accurate results from materials science simulations that can be verified with practical techniques. Eventually, such simulations on quantum computers could be more accurate and complex than simulations on classical digital computers.
