Researchers say defects and atomic vibrations can tune the nonlinear Hall effect in a topological material, opening a path toward ambient energy harvesting.

A German-led team has created and detected the long-predicted butterfly molecule, completing a 20-year search through a family of exotic ultralong-range Rydberg molecules.

Researchers in Japan have reported the first direct observation of matter-wave diffraction in positronium, the short-lived electron-positron system that has long been a target for quantum experiments.

Researchers from Stevens Institute of Technology and Colorado State University have proposed a theory in which time can exist in quantum superpositions, with ticks that may run fast and slow.

A new study reports that, in the asymptotic limit, it is possible to extract the maximum possible work from many copies of a quantum system without knowing the system’s state in advance.

Physicists in Austria say they have carried out the first experiment that appears to verify indefinite causal order, a quantum idea suggesting that the sequence of events may not always be fixed.

Physicists have discovered a novel quantum state that emerges when competing interactions leave atoms unable to settle into an ordered arrangement, opening new pathways in quantum materials research.

Physicists have developed a microscope that resolves the momentum-space structure of quantum materials with unprecedented clarity, opening new windows onto the quantum behaviors that underpin next-generation electronics.

Physicists have invisibly transferred data disguised as background thermal radiation using a phenomenon called negative light, opening new frontiers in covert communication.

Columbia University physicists demonstrated for the first time that embedding a material in a built-in light-confining cavity can alter its superconducting properties without any external stimulus.
