摘要: We give an overview of the magnetic catalysis phenomenon. In framework quantum field theory, is broadly defined as enhancement dynamical symmetry breaking by external field. start from a brief discussion spontaneous and role in its dynamics. This followed detailed presentation essential features particular, we emphasize that dimensional reduction plays profound pairing dynamics Using general nature underlying physics robustness with respect to interaction types model content, argue universal model-independent support this claim, show how realized various models short-range long-range interactions. phenomenon implies wide range potential applications: certain solid state systems cosmology, particle nuclear physics. finish review remarks about outlook for future research.
