Abstract


Introduction/purpose: Quantum field theory techniques are able to describe precisely, inter alia, collective phenomena of statistical and solid state physics.

Method: The path integral method with a Wick rotation shows its complete analogy with the partition function of statistical mechanics.

Results: The Landau-Ginzburg phenomenology successfully describes collective phenomena such as spontaneous magnetization and superconductivity.

Conclusions: Symmetry breaking phenomena could give macroscopic results.
