Figure 1: Level structure of quantum dot and spin manipulation. In order to tackle the large energy difference, we use a frequency downconversion technique that converts a single 910-nm photon ...
An optomechanical single-photon frequency shifter is demonstrated in integrated AlN waveguides. A frequency shift up to 150 GHz is achieved at telecom wavelength. The device shows near-unity ...
Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international ...
Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...
Our research revealed the frequency-dependent effects of THz photon modulation on neurons and explored the mechanism of its long-term effects.
However, this time the energy absorbed by the atom is taken from the auxiliary field and not from that of the cavity. As a result, the photon is still there after having been seen, and is ready to ...
Researchers at the European XFEL have developed a new device for X-ray measurements at high photon energies—a so-called Laue spectrometer. It enables X-ray light with photon energies of more ...
While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...
The High Energy Photon Source (HEPS), China’s flagship synchrotron radiation facility, has officially begun its joint-commissioning phase after successfully completing photon beam commissioning ...
For photosynthesis, one photon is all it takes. Only a single particle of light is required to spark the first steps of the biological process that converts light into chemical energy, scientists ...
Photon Brothers specializes in residential and commercial solar. It also offers solar maintenance, relocation and repair. Products include Qcell, the REC Group, Silfab Solar and Tesla Powerwall.
