Physicists at the University at Buffalo have proposed a quantum sensing technique that could identify altermagnets using tiny defects in diamond. The method would help confirm the properties of these recently theorized materials. It was detailed in a paper published in Physical Review Letters.

NASA's upgraded Cold Atom Lab is back in operation aboard the International Space Station, enabling new research into quantum states of matter. The facility creates Bose-Einstein condensates at temperatures near absolute zero.

Researchers have found that packed rice grains weaken under rapid compression but remain stronger under slow pressure. This unusual property has been used to create a metamaterial that automatically adjusts its behavior based on the speed of applied forces.

A new study shows that transfer learning can reduce the computational costs of searching for physics beyond the standard cosmological model by more than a factor of ten. The approach trains AI first on simpler simulations before moving to complex ones. However, it can lead to negative transfer that hinders detection of genuinely novel effects.
