Precision spectroscopy of a trapped ${}^{173}$Yb${}^{+}$ ion using a bath of ultracold atoms

Egor Kovlakov, Rene Gerritsma

We demonstrate precision laser spectroscopy of a trapped ${}^{173}$Yb${}^{+}$ ion that is not directly laser cooled by coupling it to ultracold atoms. The atomic bath continuously cools…
