Second Quantized Representation of Quantum-Mechanical Operators

1989
We are already familiar with the second quantized form of wave functions. In this section the second quantized form of various quantum-mechanical operators is going to be established. Then we shall be in a position to undertake any quantum-mechanical analysis in this representation.

Second order explicitly correlated R12 theory revisited: A second quantization framework for treatment of the operators’ partitionings

The Journal of Chemical Physics, 2007
Second order R12 theory is presented and derived alternatively using the second quantized hole-particle formalism. We have shown that in order to ensure the strong orthogonality between the R12 and the conventional part of the wave function, the explicit use of projection operators can be easily avoided by an appropriate partitioning of the involved ...

Algebraic identities relating first- and second-quantized operators

American Journal of Physics, 2000
Second-quantized operators are derived algebraically from first-quantized counterparts, thus providing an alternative to all existing methods, most of which rely upon demonstrating the equivalence of matrix elements of the two operators. This derivation establishes an operator identity between a second-quantized operator and a first-quantized operator ...
