An ultrafast optical technique uncovers new clues to the origin of bulk polarization in quantum ferroelectric materials.

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 ...

Photoelectron interference can reveal otherwise hidden properties of quantum light through an apparent attosecond time shift.

Pairing superconducting qubits with microwave cavities could reduce the hardware requirements for quantum simulations of fundamental physics. Performing simulations of quantum systems on an ordinary ...

When intense quantum light knocks electrons out of atoms, the statistics of the light can be transferred to the electrons. Strong-field ionization—a process in which intense laser light strips ...

Neutrino astronomy and the effort to build a cubic-kilometer-sized detector at the South Pole are recognized by the 2026 Nobel Prize in Physics. Neutrinos from distant astrophysical sources can reach ...

The superconductivity of uranium ditelluride (UTe 2) has a low critical temperature typical of superconducting uranium compounds. Yet its response to an applied magnetic field is extraordinary. Not ...

Regions within a cell in which biomolecules are concentrated, called condensates, form different structures when enzymes are involved, according to experiments. A biomolecular condensate is a small ...

A simplified model of the heart’s mitral valve shows that flow fluctuations can cause a soft valve to close at about one-tenth the pressure required under steady flow. Figure 1: High-speed images show ...

The shape of gold nanostructures changes depending on how they are imaged. This electron-microscope image shows a nanosized cube wrapped in a gold layer. The tiny package is the result of reactions ...

Electron microscopes are windows into the atomic world, creating images that can reveal the atomic arrangements within biological tissues or crystalline solids. But the electron beam that unveils this ...
