What’s hidden inside hematite? Applying an electric field breaks its inversion symmetry, unmasking multipolar order that’s normally hidden. New research traces this to a magnetic toroidal octupole and quadrupole.

🧲 Why is spin 3/2 special in frustrated magnets? A new study uses local conservation rules on the lattice to explain why it undergoes an abrupt phase transition while other spin values exhibit continuous transitions. Read more: https://t.co/quupnEPums

When a Haar random state splits into two subsystems, they are highly entangled. But when divided into three, a new paper shows that bipartite entanglement cannot be distilled unless one subsystem holds at least half the total qubits.
