Ultrastable Optical Clock with Neutral Atoms in an Engineered Light Shift Trap

原子物理 2009-11-10 v1

摘要

An ultrastable optical clock based on neutral atoms trapped in an optical lattice is proposed. Complete control over the light shift is achieved by employing the 5s21S05s5p3P05s^2 {}^1S_0 \to 5s5p {}^3P_0 transition of 87Sr{}^{87}{\rm Sr} atoms as a "clock transition". Calculations of ac multipole polarizabilities and dipole hyperpolarizabilities for the clock transition indicate that the contribution of the higher-order light shifts can be reduced to less than 1 mHz, allowing for a projected accuracy of better than 1017 10^{-17}.
