Sushkov’s experiments use the spins of atoms as miniature compass needles

Alex Sushkov uses a defect in a diamond to feel the tickle of a magnetic field from an individual atom or molecule.

He’s orchestrating troops of lead atoms in hopes they’ll respond to the magnetism of a hypothetical particle called the axion.

Axions are the leading candidate for the identity of the invisible “dark matter” that appears to mold galaxies and galaxy clusters.

Sushkov: If you tip a compass needle away from north, it swings straight back to north.

But if you tip quantum spin, it will kind of spiral back toward north — it wants to “precess” about the magnetic field.

In the case of axions, the hope is that we can get atoms to resonate with any axion fields that might be out there.

In dark matter, we don't even know if it’s axions or something else.

The odds may be zero , or they may be high, but curiosity is what motivates anyone to explore the unknown.

Alex Castellanos : We stand a good chance of covering most of the possible mass range for the axion.
