Quantum criticality, on the other hand, is usually associated with stranger electronic behaviors—things like high-temperature superconductivity or so-called heavy fermion metals like CeRhIn5. One strange behavior in the case of heavy fermions, for example, is the observation of large 'effective mass'—mass up to 1000 times normal—for the conduction electrons as a consequence of their narrow electronic bands. These kinds of phenomena can only be explained in terms of the collective behavior of highly correlated electrons, as opposed to more familiar theory based on decoupled electrons.
ndeed it is now recognized that proteins in plant photosynthesis utilize quantum coherence to make food. Energy from collected photons are conveyed through the plant protein by quantum electron excitations (excitons) via 8 geometrically-arrayed 'chromophores', each a non-polar group of 'pi resonance clouds'. Optimizing efficiency, the excitons propagate through all 8 chromophores simultaneously in quantum superposition.
The key to quantum coherence in photosynthesis is the non-polar, pi resonance environment in which it occurs, an environment from which, it appears, consciousness originates.
Biomolecules are generally 'amphipathic', with charged, water-soluble polar groups on one end, and an oil-like, non-polar group on the other. Oil and water don't mix. When amphipathic biomolecules self-assemble (e.g. in protein folding), the non-polar groups coalesce, forming intra-protein 'hydrophobic pockets', excluding water. The polar ends stick out into the charged, watery environment.
Non-polar hydrophobic pockets inside proteins are composed primarily of pi resonance clouds like the phenyl and indole rings of aromatic amino acids phenylalanine, tyrosine and tryptophan. Non-polar regions occur within proteins, membrane lipid bilayers and nucleic acids, e.g. DNA and RNA.
