For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring ...

For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity, as permitted by the laws of quantum mechanics, an ascending glissando of the ...

The multi-institutional team known as the JET Collaboration, led by researchers at the U.S. Department of Energy's Lawrence Berkeley National Lab (Berkeley Lab), published their results in a recent ...

A solid material that conducts electricity perfectly at certain temperatures may also qualify as an almost perfectly flowing liquid. If the result is confirmed, the superconducting material would ...

In three spatial dimensions, it is a close relative of the quark-gluon plasma, the super-hot state of matter that hasn’t existed since the tiniest fraction of a second after the big bang that started ...

Spin has an important role in quantum physics. In some ways, it is analogous to a toy spinning top rotating about its axis. In contrast to toy tops, however, quantum particles that have the smallest ...

The main object of this paper is to characterize the perfect fluid spacetimes if its metrics are Ricci solitons, gradient Ricci solitons, gradient A-Einstein solitons and gradient Schouten solitons.

The multi-institutional team known as the JET Collaboration, led by researchers at the U.S. Department of Energy's Lawrence Berkeley National Lab (Berkeley Lab), published their results in a recent ...

Physicists have observed sound waves moving through a 'perfect' fluid. The results should help scientists study the viscosity in neutron stars, the plasma of the early universe, and other strongly ...
