A team of Japanese researchers has discovered a method to control Kelvin wave excitation in superfluid helium-4. This breakthrough can refine our understanding of how energy moves in quantum fluids, ...

A free neutron outside a nucleus is not stable. It undergoes beta decay at a probability. Over time, the number of free neutrons decreases exponentially at a time constant, which is called the neutron ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

Superfluid helium represents a fascinating state of matter, manifesting unique quantum mechanical behaviours at ultralow temperatures, including frictionless flow and the absence of viscosity. In ...

Researchers have discovered how superfluid helium 3He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and classical physics of the human ...

This news release is available in German. With their SQUIDs, low-temperature specialists of the Physikalisch-Technische Bundesanstalt (PTB) have made it possible for the magnetic moments of atoms of ...

Researchers used optical trapping for the first time inside an ultracold superfluid made of helium. They were able to trap and monitor nanoparticles optically at ultralow temperatures. This technique ...
