Research reveals a surprising topological reversal in quantum systems
In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both ...

Beyond equilibrium: Scientists investigate Floquet Fermi liquids
Researchers from Germany and Singapore have studied a non-equilibrium state of Fermi liquids called the Floquet Fermi liquid (FFL), which is formed when Fermi liquids are subjected to a periodic driving force and kept in ...
Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery
Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in ...
