particle interactions and anharmonicmotion have a significant impact on the tip dynamics.
Conclusion: Our findings will be crucial for the realization of high-sensitivity force spectroscopy with cold-atom tips and could possibly allow for the development of advanced spectroscopic techniques such as Q
-control.
