Hamiltonian dynamics provides a unifying framework for the evolution of conservative systems in physics and mathematics, characterised by a function H(q,p) on a symplectic phase space of coordinates q ...

A recent study published in Physical Review Letters reveals that many widely used signatures of criticality in brain data may be statistical artifacts. They propose a more robust framework that, when ...

Using x-ray lasers, researchers at Stockholm University have been able to determine the existence of a critical point in supercooled water at around -63 °C and 1000 atmosphere. Ordinary water at ...

A hidden feature of water, long submerged, has finally been brought to the surface. New experiments have revealed supercooled water’s critical point — a specific pressure and temperature at which two ...
