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 ...

More than a century after scientists envisioned artificial photosynthesis and fusion power, neither has achieved widespread use—but slow progress is no reason to give up. This image, captured by the ...

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 ...

Through a quantum-switch experiment, researchers attempt to reveal “indefinite causal order”—a quantum phenomenon involving events in a before-and-after superposition. Artistic rendition of the ...

Measurements of the decay of the Higgs boson into muon–antimuon pairs provide evidence for the mechanism by which quarks and leptons acquire their mass. Figure 1: Display of a proton–proton collision ...

A Bose-Einstein condensate of radioactive atoms could turn into a source of intense, coherent, and directional neutrino beams, according to a theoretical proposal. Figure 1: Top: At high temperature, ...

Pairs of skyrmions—tiny whirlpools that emerge in some magnetic materials—might be able to self-propel, a behavior reminiscent of that of active-matter systems such as motile bacteria. Figure 1: ...

New physics may explain discrepant values for the ionization energy of a metastable state of helium. Aaron Bondy is a theoretical physicist at Drake University in Iowa, where he works as a ...

For a wide range of complex fluids, the transition from solid-like at rest to liquid-like when pushed can be predicted from properties of the at-rest state. Slow flow. Slow flow. Yield stress fluids ...

A high-resolution imaging system captures distant objects by shining laser light on them and detecting the reflected light. Seeing the small picture. The remote-imaging system (left) shoots eight ...

Top quarks and antiquarks have been detected in heavy-ion collisions at the Large Hadron Collider, showing that all six quark flavors were present in the Universe’s first moments. The ATLAS ...
