An optomechanical system in which light and matter exchange roles promises new kinds of quantum states.

The sloshing of light between optical waveguides replicates the quantum-mechanical exchange between an atom and an electromagnetic mode.

The next generation of ultrahigh energy lasers will be able to produce extremely dense electron-positron plasmas and intense bursts of gamma rays, according to simulations, and both will lead to new types of experiments.

A waveguide’s dielectric properties could result in an effective gauge field for photons even though they have no charge.

Quantum interference of pairs of photons emitted by nitrogen-vacancy centers in diamond paves the way for entanglement of distant qubits.
