What is a fermionic condensate?
A fermionic condensate is a superfluid phase formed by fermionic particles at low temperatures. It is closely related to the Bose-Einstein condensate, a superfluid phase formed by bosonic atoms under similar conditions. Unlike the Bose-Einstein condensates, fermionic condensates are formed using fermions instead of bosonsSource(s):rtc
What are the glitches occasionally observed by astronomers studying pulsars?
Some glitches observed in pulsars are sudden increases in their rotation rate, followed by a slower recovery to the original spin. This is thought to be caused by the transfer of angular momentum between the superfluid interior of the neutron star and its solid crust. Glitches provide valuable insights into the interior structure of neutron stars.
What is a good catch phrase for helium?
Helium is normally a gas; at very low temperatures it does liquify, but it has no solid phase, no matter how cold it gets (it does, however, have a very unusual "superfluid" phase at temperatures approaching absolute zero).
What are some examples of superfluids?
Some examples of superfluids include liquid helium, which undergoes a phase transition to a superfluid state at very low temperatures, and atomic Bose-Einstein condensates created in laboratories through ultracold temperatures. These superfluids exhibit unique properties such as zero viscosity and the ability to flow without any energy loss.
What are the Properties of condensate?
fermionic condensate is a superfluid just like a the bose-einstein codensate but this time it has the property of molecular gasses that enable the fluidity to increase its temperature
What is the superfluid vacuum theory and how does it explain the fundamental nature of the vacuum in quantum physics?
The superfluid vacuum theory proposes that the vacuum of space is not empty but filled with a superfluid that has unique properties. This theory suggests that particles and forces arise from the interactions of this superfluid, providing a deeper understanding of the fundamental nature of the vacuum in quantum physics.
Can red Mercury become a superfluid?
No
Does superfluid have a definite shape and volume?
No.
What is viscosity of super liquids?
They have no viscosity. A superfluid can even seep out of its container.
What is superfluid helium?
Superfluid helium is what you get when you cool helium to near absolute zero under normal atmospheric pressure (1 atm). From absolute zero up, the phases of helium at normal atmospheric pressure are superfluid, liquid, gas; higher pressure than atmospheric is required to produce solid helium. Superfluid is a state of matter that can only be understood using quantum mechanics. It is similar to a liquid, but different in certain ways: in particular, zero viscosity and infinite thermal conductivity. It is related to a Bose-Einstein Condensate. The term superfluid helium usually refers to superfluid ^4Helium, helium-4 with a nucleus containing two protons and two neutrons and overall quantum mechanical spin zero. Superfluid ^4He exists below about 4 degrees Kelvin (at 1 atm). The isotope ^3He, helium with a nucleus with only one neutron, exists as a superfluid at lower temperatures, below one kelvin, and different mathematics is required to describe it; the differences follow from the fact that the ^3He atom has quantum mechanical spin 1/2.
How does a superfluid flow?
It's a great thing, it's had zero viscosity I think (means it has no friction)

What is the best and worst transmitter of sound?
The worst would be a vacuum. The best probably depends on your definition of "best", but maybe something like superfluid liquid helium?
What are twotypes of matter that convection olny happens in?
Convection can happen in any state of matter in which the matter is free to move - such as a liquid, a gas, a plasma, a superfluid, a liquid crystal, etc.
