Keep cooling to 2.2 K and the helium enters its superfluid phase, called helium II. Superfluid helium has several very useful properties and is used in science and technology in multi-tonne quantities ...

One of the materials he built is a molecular net, a wall with molecule-sized pores that can allow superfluid helium to pass quantum information. The holes in this net are about one nanometer across.

Mar. 20, 2024 — Scientists have created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and ...

1. Azerbaijan is a landlocked country in Southwestern Asia bordering Armenia, Georgia, Iran, Russia and Turkey. 2. Even ...

The Pauli Exclusion Principle prevents more than one electron (an example of a fermion) per quantum state; however no such limit is imposed on particles known as bosons, such as helium-4 atoms.

How it works: the bottom animation shows how the addition of an adjustable needle valve between the refrigerator and helium reservoir prevents the relief valve from being used. (Courtesy: S.

Helium is an important resource for many applications, especially MRI machines, but the gas is hard to come by on planet Earth. While the world has been suffering a helium shortage for more than a ...

Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that ...
