how we can differentiate classical and quantum fields?i searched everywher..but i did not get a satisfactory answer
dilna said:electromagnetic field is a classical field or quantum field?in quantum we speak in erms of photons...if we go for second quantisation to electromagnetic field what we will get??
Classical fields are described by classical mechanics and follow classical laws of motion, while quantum fields are described by quantum mechanics and follow quantum laws of motion.
Quantum fields can be seen as a more advanced version of classical fields, as they take into account the principles of quantum mechanics and can describe phenomena on a subatomic level.
Some examples of classical fields include the electric and magnetic fields, gravitational fields, and fields of fluid flow.
Quantum fields include the electromagnetic field, the Higgs field, and the fields of various subatomic particles such as electrons and quarks.
Classical and quantum fields are used in a wide range of scientific research, from understanding the behavior of matter and energy in the universe to developing advanced technologies such as quantum computing and particle accelerators.
