"However, the CVF model does this because it incorporates results from initial quantum calculations of interactions between molecules. These interactions, known as many-body problems, go beyond classical physics and are due to the fact that water molecules share electrons in a way that is difficult to measure experimentally," says Franzese.

This uniquely quantum phenomenon cannot be explained by the laws of classical physics, yet it is one of the properties that explains the macroscopic behavior of quantum systems.

It exists everywhere, from our daily lives to the distant universe, while being labelled as "the last great unsolved problem of classical physics" by Richard Feynman.

Of particular interest for researchers in the field are the peculiar and bizarre properties of quantum particles -- which deviate completely from the laws of classical physics and can make materials magnetic or superconducting.

"If as we believe, quantum gravity does indeed exist, this will contribute to unite the current two worlds in physics. Today, classical physics describes the phenomena in our normal surroundings such as gravity, while the atomic world can only be described using quantum mechanics. The unification of quantum theory and gravitation remains one of the most outstanding challenges in fundamental physics. It would be very satisfying if we could contribute to that end," says Tom Stuttard, Assistant Professor at NBI.
