Physicists have finally secured direct evidence that quantum spin ice, a long-hypothesized and highly unusual state of matter, actually exists in a real material. The confirmation caps years of ...

Physicists call this strange state a quantum spin liquid, and for decades it has been one of the most elusive phases of matter in physics. Now, a new study reveals some of the clearest evidence yet ...

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful ...

Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not settle into an ordered pattern and continue to fluctuate, even at extremely ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...
