High-Temperature Superconductivity Understood at Last
A new atomic-scale experiment all but settles the origin of the strong form of superconductivity seen in cuprate crystals, confirming a 35-year-old theory.
Quantum Simulators Create a Totally New Phase of Matter
One of the first goals of quantum computing has been to recreate bizarre quantum systems that can’t be studied in an ordinary computer. A dark-horse quantum simulator has now done just that.
Physicists Create a Bizarre ‘Wigner Crystal’ Made Purely of Electrons
The unambiguous discovery of a Wigner crystal relied on a novel technique for probing the insides of complex materials.
Eternal Change for No Energy: A Time Crystal Finally Made Real
Like a perpetual motion machine, a time crystal forever cycles between states without consuming energy. Physicists claim to have built this new phase of matter inside a quantum computer.
