Query: Sensitivity of a collisional single-atom spin probe   We study the sensitivity of a collisional single-atom probe for ultracold
gases. Inelastic spin-exchange collisions map information about the gas
temperature or external magnetic field onto the quantum spin-population of
single-atom probes. We numerically investigate the steady-state sensitivity of
such single-atom probes to various observables. We find that the probe has
maximum sensitivity when sensing the energy ratio between thermal energy and
Zeeman energy in an externally applied magnetic field, while the sensitivity to
the absolute energy, i.e., the sum of kinetic and Zeeman energy, is low. We
identify the parameters yielding maximum sensitivity for a given absolute
energy, which we can relate to a direct comparison of the thermal
Maxwell-Boltzmann distribution with the Zeeman-energy splitting. We compare our
findings to experimental results from a single-atom quantum probe, showing the
expected sensitivity behavior. Our work thereby yields a microscopic
explanation for the properties and performance of this type of single-atom
quantum probe and connecting thermodynamic properties to microscopic
interaction mechanisms.
