# nLab second quantization

## Surveys, textbooks and lecture notes

The process of quantization is supposed to assign to a classical field theory a corresponding quantum field theory. One tends to imagine that in some cases the resulting QFT can itself be regarded as a classical field theory, roughly, and the process of quantization be applied again. One then speaks of second quantization .

For more see at sigma model the section Exposition of second quantization of sigma-models.
