The second quantization of quantum field theory requires that each such ball-spring combination be quantized, that is, that the strength of the field be quantized at each point in space.
This paper, using theoretical method of second quantization, obtains more brifely the form of Fermion pairs energy level, and calculates energy of Cooper pair.
Hamiltonian of magnons system was simplified by the second quantization method presented by Holstein and Primakoff. The nonlinear interaction term of Hanitltonian was dealt with by mean theory.
1 If we may be allowed one sentence for the experts: the primary function of OpenFermion is to encode the electronic structure problem in second quantization defined by various basis sets and active spaces and then to transform those operators into spin Hamiltonians using various isomorphisms between qubit and fermion algebras.↩
In 1927, Klein was appointed Lektor in Copenhagen but nonetheless continued his research working with Pascual Jordan on the second quantization in quantum mechanics.
The pivotal question was then: how to unify Maxwell's wave theory of light with its experimentally observed particle nature? The answer to this question occupied Albert Einstein for the rest of his life, and was solved in quantum electrodynamics and its successor, the Standard Model (see Second quantization and The photon as a gauge boson, below).
It was known that second quantization guarantees that photons obey Bose - Einstein statistics, but Klein showed that second quantization is not confined to free particles only.
According to our present understanding, the electromagnetic field itself is produced by photons, which in turn result from a local gauge symmetry and the laws of quantum field theory (see the Second quantization and Gauge boson sections below).
