Combining two trapping techniques reduces the motion of a levitated bead close to the point where quantum effects should become observable.
An x-ray laser has imaged the three-dimensional structure of the mimivirus by combining hundreds of measurements on single virus particles.
A proposed device would extend a quantum entanglement scheme previously demonstrated for visible photons into the microwave regime, where it could boost radar performance.
A powerful laser beam separates into many smaller filaments that undergo a phase transition similar to fluid percolating through a porous material.
Researchers characterize the multiple ways of entanglement that exist between different frequency bands in a down-converted frequency comb.
A new scheme for cooling a mechanical oscillator in a cavity may allow the observation of quantum effects on macroscopic objects and the realization of ultrasensitive gravitational-wave detectors.
Researchers generated an electron beam with very high orbital angular momentum—potentially good for atomic-scale images of the magnetism in materials.
An array of nanometer-sized aluminum pyramids acts as a directional antenna for light, and the direction depends on wavelength.
A laser-driven particle accelerator, delivering a beam of electrons with a record-breaking energy of 4.2 giga-electron-volts, could lead to compact x-ray lasers or high-energy colliders.
The polarization of an intense laser beam can theoretically be controlled by mixing it with a second beam in a plasma.
