This is a selfcontained and hopefully readable account on the method of creation and annihilation operators also known as the fock space representation or the second quantization formalism for nonrelativistic quantum mechanics of many particles. Pdf method of second quantization in the usual formalism of quantum mechanics,observables are represented by. The second quantization method is thus another representation of quantum mechanics providing alternative representations of wave functions and operators, and has, just. A bosonfermion correspondence allows an analytic definition of functional super derivative, in particular, and a bosonic functional calculus, in general, on bargmann gelfand triples for the second. In the usual formalism of quantum mechanics, the first quantization formalism, observables are represented by operators and the wave functions are normal functions.
It is important for use both in quantum field theory because a quantized eld is a qm operator with many degrees of freedom and in quantum condensed matter theory since matter involves many particles. Introduction and history second quantization is the standard formulation of quantum manyparticle theory. Pure and applied physics the method of second quantization. In the usual formalism of quantum mechanics, the first quantization formalism, observables are represented by. Pdf bosonization method for second super quantization.
The second quantization method for indistinguishable particles. Whether youve loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. In the method of second quantization, the wave functions are also expressed in terms of operators. Applying the hamiltonian to the wave function in this basis is obviously giving the same answer. Other readers will always be interested in your opinion of the books youve read. The formalism starts with the introduction of an abstract vector space, the fock. The second quantization method for indistinguishable particles lecture notes in physics, ufabc 2010. The method of second quantization deals with the method of second quantization and its use to solve problems of quantum mechanics involving an indefinite number of particles, mainly in field theory and quantum statistics. Assuming knowledge only on conventional quantum mechanics in the wave function formalism, we define the creation and annihilation operators. The method of second quantization 1st edition elsevier. Second quantisation in this section we introduce the method of second quantisation, the basic framework for the formulation of manybody quantum systems.
