Graphical method for operating in second quantization

Physical Review A, 1994
In our theoretical studies with replacement operators, we found the use of a graphical method very useful for operating with them. Now, for working with spin-orbital fermion operators, we have devised another easy graphical method which has proven to be very helpful to us.

Extraction of local spin-coupled states by second quantized operators

The Journal of Chemical Physics, 2022
We present a methodology for analyzing chemical bonds embedded in the electronic wave function of molecules, especially in terms of spin correlations or so-called “local spin.” In this paper, based on biorthogonal second quantization, the spin correlation functions of molecules are naturally introduced, which enables us to extract local singlet and ...

BAYES' FORMULA FOR SECOND QUANTIZATION OPERATORS

Stochastics and Dynamics, 2006
The Bayes' formula provides the relationship between conditional expectations with respect to absolutely continuous measures. The conditional expectation is in the context of the Wiener space — an example of second quantization operator. In this note we obtain a formula that generalizes the above-mentioned Bayes' rule to general second quantization ...

Second Quantization Operators for Spin Operators

Journal of the Physical Society of Japan, 1992
Based on the commutation relations of spin operators, the second quantization operators derived by Holstein-Primakoff and Dyson and its Hermitean conjugate operators are obtained. The matrix representations for a scalar product of two spins by the Dyson's operators are not in agreement with the rigorous one except for the case of spin 1/2, although ...

Second quantization and pseudodifferential operators

Theoretical and Mathematical Physics, 1986
In the article infinite-dimensional pseudodifferential operators are investigated. The main formulas of the calculus of these pseudodifferential operators are obtained. The so-called Schrödinger's qp-symbols for secondary quantization operators and for operators of an evolution of interacting fields are considered.
