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 ...

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 Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international ...

However, they do have energy and momentum. The energy of a photon is given by Planck's constant times the frequency of the light, and the momentum of a photon is given by Planck's constant times ...

WB frequency screening experiments showed that 34.5 THz photon stimulation increased postsynaptic density protein 95 (PSD95) expression by 26.0% compared to the control group, while THz ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...

And, almost as a bi-product of the model, we were able to produce this image of a photon, something that hasn’t been seen before in physics,” first author Dr Benjamin Yuen said in a statement.

It provides an extremely high precision of about 1.2 x 10-4 at a photon energy of around 18.6 keV. Compared to conventional spectrometers, it achieves a signal strength that is four to 22 times ...

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 ...
