I and someone was discussing something about entropy and energy transfer, etc. stuff when we came to the conclusion that energy can't be transfered from one isolated system to another. That we know. But can the isolated system transfer energy within itself? And can it if it's in absolute zero in the first place?

 

I know that no motion exists at 0 K, so the isolated system should not have any energy to transfer at all. But according to the Uncertainty Principle, energy particles can pop up from all of nowhere and disappear very quickly. Wouldn't that cause energy transfer to take place?

 

My questions seem confusing, isn't it? Well, please answer as best as you can.

You can't achieve 0 K. Any question that asks what happens after you are there is ill-formed.

To reach absolute 0, would the neutrinos passing through also have to be stopped? Is this one of the limiting factors?

No. It's one of the ways of stating the third law of thermodynamics - no finite process can reach absolute zero.
