A hallmark property of unconventional superconductivity has been discovered in a type-I superconductor, whereas it’s normally observed only in type-II materials. Superconductors can be broadly ...

Researchers have gained access to the rich physics of a landmark model magnet by assembling a crystal out of organic magnetic molecules. The S = 1 Haldane chain is an infinite 1D string of integer ...

Theorists find a persistent signature of a chaotic quantum system’s initial state, implying a memory effect—called a quantum birthmark—that resists thermodynamic equilibration. Figure 1: Evolution of ...

Researchers crushed and heated ice between diamond anvils to confirm the existence of a phase of ice that could be present in the warm mantles of ice giants. In 1986, Voyager 2 flew by Uranus and ...

Using high-power lasers to drive highly magnetized plasmas, researchers have probed the stellar processes that control coronal mass ejections. Solar force. Coronal mass ejections—such as this one ...

Two studies find that fundamental quantum constraints rule out a previously proposed neutrino-laser scheme. In last year’s proposal of a neutrino laser, the researchers sought to exploit the same ...
