Feasibility and potential of a thorium-doped barium-lithium-fluoride single crystal as a candidate for solid-state nuclear optical clock material

The authors study the feasibility of using Th:BaLiF3 single crystal as a solid-state nuclear clock material through density-functional-theory calculations. The authors then grow and characterize the crystal in the lab, demonstrating its potential for creating a solid-state nuclear clock in the future.
