A new Yb+ optical clock system for testing fundamental physics

Several clock states in Yb+, especially those within the metastable F7/2 manifold, are unusually sensitive to anticipated effects of non-Standard-Model physics. For instance, pronounced clock shifts are predicted due to Lorentz asymmetry, variations of the fine structure constant, or coupling to dark matter. Here we propose a duplex Yb+ quantum sensor dedicated to precision tests of fundamental physics. Basic design aspects of the experimental apparatus are discussed.
