The theory of non-ideal gases at thermodynamic equilibrium, for instance the van der Waals gas model, has played a central role in our understanding of coexisting phases, as well as the transitions ...

For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A wave of recent experiments is now tearing at those boundaries, revealing ...

Physicists are now watching matter behave in a way that defies everyday intuition, with atoms and even light itself arranging into structures that are rigid like a crystal yet able to flow like a ...

Tangled chains lead to shear thickening Simulations showing the emergence of chains of particles in a suspension. The image on the left shows isolated chains in a suspension with a relatively low ...
