Polarizability of ultracold ${\text{Rb}}_2$ molecules in the rovibrational ground state of ${\mathrm{a}}^3{\Sigma }_u^{+}$

Markus Deiß, Björn Drews, Johannes Hecker Denschlag +3

We study, both theoretically and experimentally, the dynamical polarizability $\alpha (\omega )$ of ${\text{Rb}}_2$ molecules in the rovibrational ground state of ${\mathrm{a}}^3{\Sigma }_u^{+}$. Taking a…
