Using sheets of light to corral waves of ultracold atoms, researchers have created an experimental platform for studying the event horizons of black holes. Making waves. Researchers have created a ...

Researchers have used radio observations of rapidly spinning neutron stars to search for signals from supermassive black hole pairs at the dawn of galaxy formation. In our lifetimes, an amazing thing ...

In a nonlinear Hall effect (NLHE), an electric field applied in the plane of a material induces a transverse voltage that depends nonlinearly on the field. This voltage can scale with either an odd or ...

Two independent teams have built operating nuclear clocks—devices that might one day rival the best atomic clocks and offer new ways to probe fundamental physics. Photograph of the thorium-229-doped ...

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 ...

Researchers have demonstrated the quantum teleportation of a 100-pixel image by a method that could help to scale up quantum networks. Quantum networks could allow information to be transmitted ...

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, ...

Different analyses of gravitational-wave observations are converging on evidence for a distinct population of massive black hole binaries produced through repeated mergers. Figure 1: Hundreds of ...

Figure 1: Barrios Hita and colleagues have explored a new path for developing a formulation of quantum theory that doesn’t rely on complex numbers [5]. In standard quantum theory, every physical ...

Figure 1: A cross section of the core of a collapsing star. Electron neutrinos (blue arrows) and muon and tau neutrinos (green arrows) are emitted and absorbed within all parts of the core. In the ...

Simulations show that knot-like magnetic structures called hopfions can be pulled apart—a capability that could be harnessed for spintronic memory devices.

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 ...
