Researchers at the University of California, Irvine have discovered a new state of quantum matter. The state exists within a material that the team reports could lead to a new era of self-charging computers and ones capable of withstanding the challenges of deep space travel.

“It’s a new phase of matter, similar to how water can exist as liquid, ice or vapor,” said Luis A. Jauregui, professor of physics & astronomy at UC Irvine and corresponding author of the new paper in Physical Review Letters.

“It’s only been theoretically predicted—no one has ever measured it until now.”

Physicists at UC Santa Barbara have become the first to experimentally observe a quirky behavior of the quantum world: a “quantum boomerang” effect that occurs when particles in a disordered system are kicked out of their locations. Instead of landing elsewhere as one might expect, they turn around and come back to where they started and stop there.

“It’s really a fundamentally quantum mechanical effect,” said atomic physicist David Weld, whose lab produced the effect and documented it in a paper published in Physical Review X. “There’s no classical explanation for this phenomenon.”

Scientists find twisting 3D Raceway for Electrons in Nanoscale Crystal Slices

Mysterious quantum properties in material point to new applications in electronics. Researchers have created an exotic 3D racetrack for electrons in ultrathin slices of a nanomaterial they fabricated at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) The international team of scientists from Berkeley Lab, UC Berkeley, and Germany observed, for the first time, a unique behavior in which electrons rotate around one surface, then through the bulk of the material to its opposite surface and back.

The possibility of developing “topological matter” that can carry electrical current on its surface without loss at room temperature has attracted significant interest in the research communit...

New Protocol to detect Entanglement of Many-Particle Quantum states has been developed. These systems could help us not only to improve our understanding of matter but to develop measurement techniques beyond current existing technologies. Entanglement is a consequence of the probabilistic rules of quantum mechanics and seems to permit a peculiar instantaneous connection between particles over long distances that defies the laws of our macroscopic world – a phenomenon that Einstein referred to as “spooky action at a distance.”
