    Optical Pumping of TeH+: Implications for the Search for Varying mp/me

    Molecular overtone transitions provide optical frequency transitions sensitive to variation in the proton-to-electron mass ratio (μ≡mp/me\mu\equiv m_p/m_e). However, robust molecular state preparation presents a challenge critical for achieving high precision. Here, we characterize infrared and optical-frequency broadband laser cooling schemes for TeH+^+, a species with multiple electronic transitions amenable to sustained laser control. Using rate equations to simulate laser cooling population dynamics, we estimate the fractional sensitivity to μ\mu attainable using TeH+^+. We find that laser cooling of TeH+^+ can lead to significant improvements on current μ\mu variation limits
