摘要：
An upper bound is placed on a combination of CPT- and Lorentz-violating quantities using data from a Penning-trap experiment with a single trapped electron. The experiment involves searching for diurnal variations in the electron anomaly frequency. The theoretical framework is a standard-model extension that violates these symmetries. The figure of merit for Lorentz and CPT symmetry in this context is bounded at 1.6 parts in 10(21).
