We present the progress towards the first realization of an optical lattice clock based on the Bosonic 24Mg 1S 0 – 3P 0 optical transition. We achieve the highest Q-factor for Mg with linewidths below 50 Hz which allows a precise determination of t

We optically excite the electronic state 3s3p ^{3}P_{0} in ^{24}Mg atoms, laser cooled and trapped in a magic-wavelength lattice. An applied magnetic field enhances the coupling of the light to the otherwise strictly forbidden transition. We determin

104 magnesium atoms have been trapped in an optical lattice at the predicted magic wavelength of 469 nm. The trap depth of the lattice sites is 16 Er corresponding to a Lamb-Dicke parameter of η = 0.51. The temperature of atoms in the lattice is 10

We load ${10}^{5}$ magnesium atoms in a dipole trap from a millikelvin-hot magneto-optical trap (MOT) using a continuous-loading scheme. Light-assisted two-body processes limit the maximum achievable density in a MOT, resulting in a reduced transfer

Optical atomic clocks have large potential regarding accuracy and stability compared to the best microwave clocks. Alkaline-earth magnesium (Mg) is a promising candidate for a future neutral atom optical clock due to its low sensitivity to blackbody

Magnesium (Mg) is an attractive candidate for a neutral atom optical clock. It shows low sensitivity to black body radiation induced frequency shifts - the dominant uncertainty contribution in today's most accurate neutral atom optical clocks [1]. In
