Physicists reach atomic-scale telegraphy with light

In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking ...

Twisting and binding matter waves with photons in a cavity

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it ...

Visual observation of photonic Floquet–Bloch oscillations

Recently, the exploration of Bloch oscillations (BOs) in periodically driven quantum systems, equivalent to "Floquet systems," has drawn tremendous attention because their exotic characteristics are profoundly distinct from ...
