Query: Measurement of Ion Motional Heating Rates over a Range of Trap
  Frequencies and Temperatures   We present measurements of the motional heating rate of a trapped ion at
different trap frequencies and temperatures between $\sim$0.6 and 1.5 MHz and
$\sim$4 and 295 K. Additionally, we examine the possible effect of adsorbed
surface contaminants with boiling points below $\sim$105$^{\circ}$C by
measuring the ion heating rate before and after locally baking our ion trap
chip under ultrahigh vacuum conditions. We compare the heating rates presented
here to those calculated from available electric-field noise models. We can
tightly constrain a subset of these models based on their expected frequency
and temperature scaling interdependence. Discrepancies between the measured
results and predicted values point to the need for refinement of theoretical
noise models in order to more fully understand the mechanisms behind motional
trapped-ion heating.
