Lorentz symmetry and Penning Traps

The Standard-Model Extension has been used to analyze the Penning-trap, a laboratory device that uses electric and magnetic fields to confine charged particles. The goal of these studies has been to find potential signals for Lorentz violation. Papers include:

For an overview of some of the basic theory in these papers, see the presentation Low-energy precision studies in quantum systems given at the June 2013 Summer School on the Lorentz- and CPT-violating Standard-Model Extension.
