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 ...

A carbon nanotube foam springs back to its initial state, regardless of the speed of the compression, a property that could lead to a new type of shock absorber. Perfect padding. Vertically aligned ...

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 ...

New experiments suggest that superconductivity in twisted bilayer graphene depends on an unconventional electron-pairing mechanism. Figure 1: Two twisted bilayer graphene (TBG) layers stacked one on ...

A ring of optical fiber can be made to host phenomena that originated in the realm of high-energy physics. Yang and his colleagues achieved their feat using a platform based on fiber ring resonators, ...

Before determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed. Quantum fluctuations ...

Researchers have proposed methods to tune the properties of altermagnets, a step toward practical applications for this new form of magnet. New theoretical work outlines how to create a switchable ...

Time crystals realized in the so-called quasiperiodic regime hold promise for future applications in quantum computing and sensing. In ordinary crystals, atoms or molecules form a repeating pattern in ...

The demonstration that ions can be precisely manipulated in a trap containing integrated photonics paves the way for a large-scale trapped-ion quantum processor. Figure 1: Mordini and colleagues ...

The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries. The wave nature of electrons is revealed in ...
