Photon field quantization
WebQuantization of the EM Field. The Hamiltonian for the Maxwell field may be used to quantize the field in much the same way that one dimensional wave mechanics was quantized. The radiation field can be shown to be the transverse part of the field while static charges give rise to and . We decompose the radiation field into its Fourier components ... WebOct 30, 2015 · However, one can easily check that a photon in the mode has the energy when substituting the above field operators into the three-dimensional analog of equation …

WebPhoton is the quantum of light and light is electromagnetic wave which carries momentum and energy. i.e, If the total energy transferred to a surface in time t is U, then p=U/c . So there, is interaction of photon with matter. Take an example you can see the surrounding because photons interact with matter. Comment. WebMar 29, 2024 · Field quantization doesn't require a photon picture. A measurement device that creates a record that corresponds to the Planck spectrum just has to be modeled by an operator that has (in the given state) that probability distribution associated with its continuous spectrum (or else by a POVM). That doesn't require a photon picture.

An exception is the case of linear canonical transformations, where, with the right understandings, quantization does commute with the classical transformation. In quantum field theory other methods of quantization have been developed that are easier to
