Researchers verify relationship between rate of a nonequilibrium process and the rate at which it creates entropy

A team of researchers affiliated with multiple institutions in China has verified the relationship between the rate at which a nonequilibrium process happens and the rate at which it creates entropy. In their paper published in the journal Physical Review Letters, the researchers describe experiments with individual calcium atoms in an ion trap and findings about the relationship between their lifespan and the rate at which they are able to exchange energy using different types of baths.
