Atomic, molecular and optical (AMO) physics explores the quantum behaviour of electrons, atoms and light, and their mutual interactions across energy, length and time scales. In atoms and molecules, ...

Physicists and chemists at Heidelberg University have realized a photonic microchip that is driven by light just as easily as electronic components via a "plug." Their development could serve as the ...

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

An international team of researchers has shown that superconductivity can be modified by coupling a superconductor to a dark electromagnetic cavity. The research opens the door to the control of a ...

In the dynamic realm of optical physics, researchers are continually pushing the boundaries of how light can be manipulated and harnessed for practical applications. As reported in Advanced Photonics ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

In June, more than 1,200 physicists will present new research at the 56th Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics being held in Portland, ...

Glass nanostructures etched using high-intensity femtosecond laser pulses promise to keep vast quantities of data safe for billions of years, describe Peter Kazansky, Ausra Cerkauskaite and Rokas ...

Researchers show that precisely layering nano-thin materials creates excitons -- essentially, artificial atoms -- that can act as quantum information bits, or qubits. By taking two flakes of special ...

As digital data streams increase in speed and data rate, losses in PCB traces become ever more of a bottleneck.
