Abstract

The mechanism of the dynamical rearrangement of symmetry in quantum field theory underlies the phenomenon of coherent boson condensation in the vacuum state. Coherent states appear to be related to fractal self-similarity. The dynamical paradigm of coherence opens the way to an integrated vision of natural phenomena and it may possibly rule morphogenetic processes. Robustness properties of physical systems, such as dynamical and functional robustness, topological robustness, multilevel and semantic robustness may find their root in coherence. Possible extension to biology and neuroscience is discussed.
