“…We find that, for θm f > 0, the CP potential retains its usual attractive form, while for θm f < 0 it acquires a positive maximum V CPmax located at a distance B max , thus implying the CP potential turns out to be repulsive for distances b > b max . This is consistent with previous calculations which show that Casimir forces can be repulsive if they involve magnetic moments couplings [56,57]. In a similar fashion, it was recently shown that the dynamical properties of the atomic electron can be tuned with the TMEP θ [58].…”

An electric charge near the surface of a topological insulator (TI) induces an image magnetic monopole. Here we study the spectra of hydrogenlike ions near the surface of a planar TI, taking into account the modifications which arise due to the presence of the image monopole magnetic fields. In fact, the atom-TI interaction provides additional contributions to the Casimir-Polder potential while the ion-TI interaction modifies the energy shifts in the spectrum, which now became distance dependent. We show that the hyperfine structure is sensitive to the image magnetic monopole fields in states with nonzero angular momentum, and that circular Rydberg ions can enhance the maximal energy shifts. We discuss in detail the energy splitting of the nP 1/2 and nP 3/2 states in hydrogen. We also analyze the Casimir-Polder potential and find that this magnetic interaction produces a large distance repulsive tail for some particular atomic states. A sizable value of the maximum of the potential requires TIs with very low values of the permittivity together with high values of the topological magnetoelectric polarization.

“…This is a surprising claim, since over its close to sixty year history there has been a host of applications to which the PZW Hamiltonian has been applied, which have agreed with, or led to predictions borne out by experiment. There are many hundreds of papers in the established literature citing the original work, bearing testimony to its efficacy and success; numerous significant applications and advances have built upon it, even over the last decade [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37]. Indeed we know of no cases where the theory has been faulted by experimental studywhich would usually be the condition to invite reappraisal of a previously successful theory.…”

The multipolar Hamiltonian of quantum electrodynamics is extensively employed in chemical and optical physics to treat rigorously the interaction of electromagnetic fields with matter. It is also widely used to evaluate intermolecular interactions. The multipolar version of the Hamiltonian is commonly obtained by carrying out a unitary transformation of the Coulomb gauge Hamiltonian that goes by the name of Power-Zienau-Woolley (PZW). Not only does the formulation provide excellent agreement with experiment, and versatility in its predictive ability, but also superior physical insight. Recently, the foundations and validity of the PZW Hamiltonian have been questioned, raising a concern over issues of gauge transformation and invariance, and whether observable quantities obtained from unitarily equivalent Hamiltonians are identical. Here, an in-depth analysis of theoretical foundations clarifies the issues and enables misconceptions to be identified. Claims of non-physicality are refuted: the PZW transformation and ensuing Hamiltonian are shown to rest on solid physical principles and secure theoretical ground.

“…This weak electromagnetic force is a result of noise currents composed of noise polarization and noise magnetization in matter, which are described by macroscopic electric and magnetic quantities. The noise currents act as a source for a quantized electromagnetic field, which can be expanded in terms of the classical electromagnetic Green's tensor for the Helmholtz equation [5][6][7][8][9][10]. By computing the interaction of an atom with this field one can compute the effect of material bodies on the internal properties of the atom.…”

Casimir-Polder shift and decay rate in the presence of nonreciprocal media

We calculate the Casimir-Polder frequency shift and decay rate for an atom in front of a nonreciprocal medium by using macroscopic quantum electrodynamics. The results are a generalization of the respective quantities for matter with broken time-reversal symmetry which does not fulfill the Lorentz reciprocity principle. As examples, we contrast the decay rates, the resonant and nonresonant frequency shifts of a perfectly conducting (reciprocal) mirror to those of a perfectly reflecting nonreciprocal mirror. We find different power laws for the distance dependence of all quantities in the retarded and nonretarded limits. As an example of a more realistic nonreciprocal medium, we investigate a topological insulator subject to a time-symmetry breaking perturbation.
