superfluid

She was able to achieve this by using a superfluid.

In 1999, one type of superfluid was used to trap light and greatly reduce its speed.

They share the main idea but differ in how the structure and properties of the background superfluid must look like.

Despite having no viscosity, turbulence is possible in a superfluid.

How a superfluid could flow through a solid defies ready explanation.

Some of the things a superfluid can do is:

When poured in a beaker, a superfluid will flow up the sides and out.

Once the first critical angular velocity is reached, the superfluid will form a vortex.

However, there is a well-known mechanism by which a superfluid may be formed from fermions.

Another fundamental property becomes visible if a superfluid is placed in a rotating container.

This property is evidenced, among other areas, in helium-4 when it is cooled to become a superfluid.

Because superfluid has very high thermal conductivity, it makes an excellent coolant.

Similar to a superfluid, a supersolid is able to move without friction but retains a rigid shape.

A superfluid is a special kind of fluid that has properties that are different from normal fluids.

Dr. Leggett expanded his calculations and worked out properties of the superfluid.

Some success has been achieved in using string theory methods to describe the transition of a superfluid to an insulator.

It also has infinite thermal conductivity so that no temperature gradient can form in a superfluid.

The circulation around any closed loop in the superfluid is zero, if the region enclosed is simply connected.

For example, if helium-4 as a superfluid is placed in an open container, it will climb the walls of the container and spill out.

Any quantity of neutronium may be considered a single atomic nucleus; however, under most conditions the substance will behave as a superfluid.

Placing a superfluid in a spinning container will result in quantized vortices.

Fermionic condensates are a type of superfluid.

The vortex strength is quantized, that is, a superfluid can only spin at certain "allowed" values.

It is a superfluid.

Mrs. Jin suspects that this pairing process is the same in Helium-3, also a superfluid.
