1) Water as a macroscopic quantum system

Quantum physics describes the laws that govern the microscopic world of single particles or molecules, whereas classical physics apply to macroscopic systems. There are a few exceptions where the bizarre features of the quantum world become visible macroscopically. Superfluid liquid helium is an example hereof, and liquid water can be considered another, even more special one. This session deals with the quantum field description of liquid water, experimentally observable features through boson condensation, and the breath-taking consequences for physics and emerging technologies.

An enzyme is a protein that catalyses a chemical reaction. The Ecto-NOX protein is unusual in that it catalyses two different reactions, and alternates between them with a period of 24 minutes. James and Dorothy Morré have been investigating the basis of this oscillation for over 30 years, and ten years ago they were surprised to find that water plays a key role in this oscillation. Their conclusion was that the oscillation is linked to changes in the proportion of the two spin isomers of the water molecules that surrounds the protein. More recent work by others casts doubt on this interpretation of the experimental results. An alternative interpretation will be presented where the oscillation is linked to a long range quantum interaction between the water molecules. The results of the Morrés’ investigations into the Ecto-NOX oscillation is consistent with an interaction between water molecules that is associated with the spins of the protons that form the nucleus of the hydrogen atoms.
