Do Electrons Stop Moving at Absolute Zero Temperature - What Happens at Absolute Zero Temperature

This video explains, Do Electrons Stop Moving at Absolute Zero Temperature and What Happens at Absolute Zero Temperature. This video also explains the Heisenberg uncertainty principle in quantum mechanics.
Do electrons stop moving at absolute zero temperature? The answer is- No.
Electrons inside an atom continue to move even at the lowest possible temperature known as the absolute zero temperature.
It's value is -273 degree Celsius or 0K.
Actually it is the random motion of atoms and molecules in the matter that is responsible for its temperature not the motion of electrons in the atom.
So at the absolute zero temperature atoms and molecules come to rest but not the electrons.
As it's not possible to slow down the motion of atoms which are already at rest, so we cannot get lower temperature than the absolute zero.
According to the Heisenberg's uncertainty principle in quantum physics, it's not possible to measure the exact position and momentum of a particle at the same time.
So if electrons come to rest we would know their exact position and exact momentum which is zero for rest.
But it's not possible according to the uncertainty principle.
It means electrons keep moving even at the absolute zero temperature.

Thank you very much I was having this doubt since several months and exactly about the fact that if they stop movingwe can measure the velocity and position
Thanks for clearing my doubt man!!!

It would make sense that the reason electrons don't stop or can't stop is because there are no standing waves. You can make electronic standing waves at many temperatures but the electrons you perceive in a standing wave are not the electrons you saw picoseconds ago. Actually, there's no possible way that we know of to measure any electron twice like a snap shot of a picture. The interactions all happen on unfathomable short distances at nearly the speed of light. The interactions are moderated by light but it's not light in excess of the system so we cannot see it. Seeing it would require excess photons. We can deduce interactions magnetically by probing but no where near the resolution which could give a picture of the interactions.

Very interesting and informative! Thank you!.

Idea for consideration...If we make an assumption that electrons did in fact stop moving at absolute zero, wouldn't that still fit the Heisenberg Uncertainty Principle.
I mean, we could tell for a certainty where it is and where it is going. "It is going nowhere because it is frozen in place and the speed, momentum, inertia, etc. all have the value of zero."

Of course we all realize that it is a mute point since nothing can reach absolute zero without some sort of divine intervention because the physical universe lacks the ability to cool itself that much.

It does seem that as long as electrons are moving, then there is still energy within the matter. Any movement would cause heat of some sort, though infinitesimally small. To stop the motion, we would need to remove that energy.

Since we're interested in motion, the Heisenberg Uncertainty Principle doesn't play a role because if we measure the momentum of the electron to be greater than zero, we're done and losing track of position wouldn't be a penalty since the interest is with the motion.

[nicolaslacombe]

Is there any info on the behavior of quarks, muons, gulons etc. in these types of conditions?

[franshartman]

As zero K is impossible to reach, the question seems irrelevant. We can only measure the position or momentum of an electron at positive K.

[beleuf]

It doesn't prove nothing, the Heisenberg principle wasn't made thinking about the zero motion in 0K, so one could say that electrons does stop at 0K until proven wrong.

Top! Realy good synthesy! We cannot dy stupid!

[aleksandararabadzhiev]

The Haisenberg principle is only applicable to positive K so no one knows what would happen to electrons at absolute zero.

[adairjanney]

why does temperature make atoms move faster?

[aroobarahat]

Absolute zero motion of atom cease so we cannot measure the speed and mass( momentum) ...but electron will keep on moving inside the atom ... according to uncertainty principle...
But question is that if the thing is at rest we can measure mass ( but velocity be zero) so indirectly momentum will be zero

[shaqatwinters]

In order to remain in the physical there have to be safe me form of movement? Without it it couldn’t exist in the physical dimension?

[shirinshaikh]

If electrons are moving then some energy will be present there and temperature is proportional to energy means there will be some temperature, then how the temperature will 0 Kelvin ??

[agentoffortune]

If the speed of inner shell electrons would have to exceed the speed of light as in element 138, would any elements with atomic number 138 or higher be able to exist?

[jsuryakan]

At any temperature electron moves.but is it 2D or 3D.
