The principle of symmetric bracket invariance as the origin of first and second quantization

Theodore Garavaglia, Steven Kenneth Kauffmann

The principle of invariance of the c-number symmetric bracket is used to derive both the quantum operator commutator relation $[\hat q, \hat p]=i\hbar$ and the time-dependent Schrödinger equation. A c-number dynamical equation is found which leads to the second quantized field theory of bosons and fermions.

New ordering rule and Lie bracket of quantum mechanics

Slobodan Prvanović

The algebraic multiplication of quantum mechanics is defined as two step operation. 1 The first step is ordinary multiplication while the second is application of the superoperator - symmetrizer. This allows introduction of Poisson bracket as the Lie bracket of quantum mechanics which results in obstruction free quantization.

Dyck language and fermionic second quantization: I. Theory

Jérémy Morere, Thibaud Etienne

This paper proposes a novel framework connecting fermionic second quantization and Dyck languages. By defining translations of creation and annihilation operators using bracket alphabets, the study establishes nullity criteria for expectation values of chains of second quantization operators. Those translations are designed to reveal sufficient conditions for the nullity of the expectation values relatively to one-determinant states or to the physical vacuum. The nullity criteria are purely syntactic, and simply reduce to the inspection of sequences of opening and closing brackets. Moreover, numbers and transformations in Dyck languages can be imported in the context of fermionic second quantization. One of these numbers, the depth, originally absent from second quantization, can be used to introduce more nullity criteria.

The principle of invariance of the c-number symmetric bracket is used to derive both the quantum operator commutator relation [q^,p^]=iℏ[\hat q, \hat p]=i\hbar[q^​,p^​]=iℏ and the time-dependent Schrödinger equation. A c-number dynamical equation is found which leads to the second quantized field theory of bosons and fermions.
