Instead of quantizing the vector potential A^μ why we do not directly quantize the B and E fields in electrodynamics.
That's exactly the point.Bill_K said:You still have to quantize using the canonical variables A and E ≡ A·.
Let's look at some action S in terms of some variables x, y, ... and their time derivatives dx/dt, dy/dt, ...mritunjay said:... can somebody explain to me why E and B are not canonically conjugate variables?
Quantization of electromagnetic field is a theory in quantum mechanics that describes the discrete nature of electromagnetic radiation. It states that the energy of electromagnetic radiation is not continuous, but rather exists in small, discrete packets called photons.
Quantization of electromagnetic field is important because it provides a more accurate description of the behavior of electromagnetic radiation. It allows for a better understanding of phenomena such as the photoelectric effect and the emission and absorption of light by atoms.
The concept of quantization of electromagnetic field is closely related to the wave-particle duality of light. It explains how light, which was previously thought to only exhibit wave-like behavior, also behaves as a particle (photon) when interacting with matter.
One example of quantization of electromagnetic field in action is the measurement of the energy levels of electrons in an atom. The energy levels can only take on discrete values, which can be explained by the quantization of electromagnetic radiation.
Yes, quantization of electromagnetic field is a well-established theory that has been tested and supported by numerous experiments. It is an essential component of quantum mechanics, which is one of the most successful and extensively tested theories in physics.
