Ordinary matter, when cooled, transitions from a gas into a liquid. Cool it further still, and it freezes into a solid.

Physicists have observed a strange new quantum phase in a graphene-based system, where a superfluid appears to freeze into a solid-like state. Cooling usually pushes matter through a simple sequence.

Solid-state batteries are widely viewed as a key technology for the future of energy storage, particularly for electric ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...
