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 ...

How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse—in which the water flows into the device rather than out of it—work? Through a series of experiments, ...

Thermoelectric permanent magnet opens new possibilities in thermal management technologies

A research team has demonstrated that the transverse thermoelectric conversion (i.e., energy conversion between charge and heat currents that flow orthogonally to each other) can be greatly enhanced by applying magnetic fields ...
