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.

Thread closed.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
