Phys. Rev. A 76, 022106 (2007) [6 pages]Electrodynamics of a compound system with relativistic correctionsReceived 19 May 2007; published 24 August 2007 The electromagnetic interaction of a moving compound charged system with leading relativistic corrections is studied. An effective Hamiltonian is obtained by using a set of canonical transformations, and it is demonstrated that the coupling of the total motion to internal degrees of freedom is uniquely determined by Lorentz covariance. Several known results such as the Röntgen term and the interaction of the spin with the electric field are recovered, and new results for various relativistic and recoil corrections are obtained. © 2007 The American Physical Society URL:
