When the Universe reaches heat death, at absolute zero, do atoms remain intact, or do they degrade into elementary particles?

I'm sorry if the question is a bit unclear; my boyfriend and I were having an argument last night on whether or not, when the Universe reaches heat death, matter still exists as atoms, or do those atoms degrade into elementary particles? 
In short, could I theoretically detect atoms of matter, or, does the strong nuclear force stop working at absolute zero and those atoms degrade into neutrons, protons and electrons?

Edit : corrected strong magnetic force to strong nuclear force.

Though there is no experimental evidence, there are a lot of theories which suggest that protons can eventually decay. As neutrons decay after about 15 minutes outside of an atomic nucleus, this would mean that all atomic matter would eventually decay.
At the same time, the Standard Model (which is the dominant theory in particle physics, it predicted the Higg's Boson) states that protons are stable, and will not decay.
Also, finding out whether or not a nucleus is stable or not is a game of staring at it and waiting to see if it decays, bismuth 209 was recently found to have a finite lifetime after previously being thought to be stable.

By the way, the force that keeps nuclei together is called the strong nuclear force, it's not related to magnetism.
