A Generalization of the Second Quantization Method to the Case of Special Tensor Products of Fock Spaces and Quantization of Free Energy

The many-particle Schrödinger operator in Fock spaces is averaged by a method that is a generalization of the averaging given in the author's paper (33, No. 4, 50–64). This provides a new representation of the Schrödinger equation, which is a direct generalization of the second quantization representation. The resulting correspondence between symbols and operators permits one to quantize entropy as well as free energy.
