Reduced Planck Constant vs Dark Matter?

[jwb44]

TL;DR Summary

Is the Reduced Planck Constant the minimum frequently/movement/spin matter can have to exist?

Is the Reduced Planck Constant the minimum frequently/movement/spin matter can have to exist?

So if a matter were to spin lower than 1.054 571 817... x 10-34 J s, it when cease to exist?
Or would matter falling below the Reduced Planck Constant by classified as Dark Matter?
I heard that Higgs boson and axion have 0 spin. But are we sure that the Higgs boson and axion have 0 spin? that would mean 1.054 571 817... x 10-34 J s x 0 = 0. How could they exist with an energy state lower 1.054 571 817... x 10-34 J s? And what would be the lowest energy state possible for a particle to exist? And is it theoretically possible to reduce the 1/2 spin of fermions to 0 spin? what would happen?

The response by @Vanadium 50 appears to cover it. The only note I would add is that Planck's constant does not represent an "energy state"; its units aren't units of energy.
