Abstract :
We describe the frequency shifts for trapped fermions, as in a optical lattice clock. We discuss the behavior of the shift and show that it is not proportional to the difference of partial densities, in contrast to previously observed clock shifts. We provide a simple counter-example and also show that large interactions may effectively cancel the frequency shifts due to collisions.
