superfluid

[¦sü·pər′flü·əd]
(physics)
A collection of particles which obey Bose-Einstein statistics and are all in the lowest energy state allowed by quantum mechanics, having zero entropy and zero resistance to motion; examples are a fraction of the atoms in liquid helium II and a fraction of the pairs of electrons in a superconductor.

"But then, a second soup of superfluid that moves in the core catches up to the first causing the spin of the star to slow back down.
Maxwell's treatment however, focused more upon the rotational component of the energy and granted the aether qualities which were unfamiliar in fluids and have only more recently been demonstrated to actually exist in superfluids.
During the conference, EY Industry Research Center leader ByeonJoon-young said the ongoing Fourth Industrial Revolution is in a "superfluid," or rapidly changing state.
Physically, it describes a superfluid state of Cooper pairs with zero momentum when the pairing is only between atoms with equal and opposite momenta.
Note that the first example of "superfluid" black holes always has a hyperbolic horizon [20].
In (3), if we set l(u) = u, that is, [g.sup.2](u) = 1 + 2[u.sup.2], then we get the superfluid film equation in plasma physics:
When the space or vacuum for the path of one beam is polarized by the scalar field generated by charged objects, superconductor disks, and/or superfluid toruses, the interference pattern will be varied or shifted.
Ultracold gases in optical lattices constitute an extraordinary tool for the analysis of strongly correlated gases under extremely well controlled conditions [1, 2], as highlighted by the observation of the superfluid to Mott-insulator (MI) transition in ultracold bosons [3], recently followed by the realization of the metal to MI transition in two-component fermions [4, 5].
Our testers protect their face with three mini sun potions: Soap & Glory Make Yourself Youthful Sunshield Superfluid SPF50+, PS15 for 30ml, Boots I LOVED the summery scent of this UVA/UVB lotion.
Washington, Apr 13 ( ANI ): A team of astronomers from the University of Amsterdam has discovered that sudden speed jumps in the rotational velocity of pulsars have a minimum size, and that they are caused not by the unpinning and displacement of just one sub-surface superfluid vortex, but by billions.
The residual term can be due to the presence of nodes in the superconducting gap, a special superconducting phase (like superfluid phase A1 of [sup.3]He), a band of gapless superconductivity (due to impurities), or an inhomogeneous sample (partly nonsuperconducting).
