Do macroscopic bodies also show quantum nature at extremely low temperatures?

If we consider atoms or molecules and cool them to extremely low tempertures, will they also show quantum nature. Will their wave nature also get dominated? And if they are bosons, will they become a Bose-Einstein condensate?

• It sounds like you have some ideas as to why that may be true, so you should add those ideas to your question. – PM 2Ring Jan 24 at 5:02

A macroscopic mechanical resonator having a high frequency $$\omega$$ can display quantum properties at low temperature T (say, if $$\hbar\omega>kT$$) (https://physicsworld.com/a/quantum-effect-spotted-in-a-visible-object/)
