  2. Photon - Wikipedia

    en.wikipedia.org/wiki/Photon

    Photons seem well-suited to be elements of an extremely fast quantum computer, and the quantum entanglement of photons is a focus of research. Nonlinear optical processes are another active research area, with topics such as two-photon absorption , self-phase modulation , modulational instability and optical parametric oscillators .

  3. Magnetic photon - Wikipedia

    en.wikipedia.org/wiki/Magnetic_photon

    In physics, a magnetic photon is a hypothetical particle. It is a mixture of even and odd C-parity states and, unlike the normal photon , does not couple to leptons . It is predicted by certain extensions of electromagnetism to include magnetic monopoles .

  4. Photomagnetic effect - Wikipedia

    en.wikipedia.org/wiki/Photomagnetic_effect

    Under the proper circumstances, the photon's magnetic fields effect is as strong as their electric field – as e.g. in solar cells. The discovery is a surprise, because it is not straightforward to derive the strong magnetic effect from the physical equations, and thereby indicate that this quantum mechanical effect would be interesting enough.

  5. Quantization of the electromagnetic field - Wikipedia

    en.wikipedia.org/wiki/Quantization_of_the...

    Photons are massless particles of definite energy, definite momentum, and definite spin. To explain the photoelectric effect , Albert Einstein assumed heuristically in 1905 that an electromagnetic field consists of particles of energy of amount hν , where h is the Planck constant and ν is the wave frequency .

  6. Virtual photon - Wikipedia

    en.wikipedia.org/wiki/Virtual_photon

    These classifications are based on the direction of the energy and momentum of the virtual photons and their contribution to the electromagnetic force. [2] Virtual photons can have a range of polarizations, which can be described as the orientation of the electric and magnetic fields that make up the photon. The polarization of a virtual photon ...

    Photons that don’t easily interact with each other, for example, can be used in communication to offer near distortion-free transfer of information at light speed.

  8. Photomagnetism - Wikipedia

    en.wikipedia.org/wiki/Photomagnetism

    The energy diagram of the transitions between the ground state and the magnetic state. Solid arrows represent absorption of photons and dashed arrows represent non radiative processes. Photomagnetism (photomagnetic effect) is the effect in which a material acquires (and in some cases loses) its ferromagnetic properties in response to light.

  9. Absorption (electromagnetic radiation) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(electromagnetic...

    Upon striking the sample, photons that match the energy gap of the molecules present (green light in this example) are absorbed, exciting the molecules. Other photons are scattered (not shown here) or transmitted unaffected; if the radiation is in the visible region (400–700 nm), the transmitted light appears as the complementary color (here ...
