Sentences with phrase «small number of photons»

The current experiments use such a small number of photons that it would take a standard laptop a fraction of a second to make the same calculation.

Because one of the leading techniques is the manipulation of small numbers of photons, one critical need has been for a highly efficient photon counter that can measure the number of photons in a pulse of light.

Not exact matches

In the quantum world, physicists study the tiny particles that make up our classical world — neutrons, electrons, photons — either one at a time or in small numbers because the behaviour of the particles is completely different on such a small scale.

The authors found that their heat engine model only yields high efficiency and output power when the number of photons involved is small; accordingly, its efficiency and power output rapidly decrease as the number of photons increases.

Stephen Hawking theorized in 1974 that black holes radiate small numbers of particles (mainly photons), a process known as «Hawking Radiation».

A very small number of microwave photons are sent into the box where their quantum fields interact with the superconducting circuit.

A number of infinitesimally small, dust devil — like energy vortices called quarks and photons collectively make up the structure of the atom.

To select a small number of parameters conveying the maximal information about the [photon] shower shape, we uncorrelated the above parameters through a principal component analysis in which these seven parameters are transformed into new seven uncorrelated parameters given by the eigenvectors of the covariance matrix.

i.e. if c is higher, then also dQ must be higher in order to get the same dT with the same m. Thus the same number of the longwave photons will give a smaller rise of temperature of water as compared to the material in the pavement.

So to argue for the insignificance of the thermosphere to radiative balance it is not sufficient to point to its small mass and number of molecules — one must accompany this with physics showing for instance the mean free path of photons between interactions with air molecules to be sufficiently long that the thermosphere will not significantly affect outgoing flux.
