Abstract

We develop a formalism to incorporate exchange symmetry considerations into the calculation of collisional frequency shifts for atomic clocks using a density-matrix formalism. The formalism is developed for both fermionic and bosonic atomic clocks. Numerical results for a finite-temperature ⁸⁷Sr ¹S₀ (F=9/2) atomic clock in a magic wavelength optical lattice are presented.
