“…See (C11) for details. The bi-isotropic relations (9) have been much studied in both theoretical and applied respects [13][14][15][16][17][18][19], being also important to address properties of topological insulators [20][21][22][23][24][25][26][27], axion electrodynamics [28][29][30], construction of optical isolators from chiral materials [31], Casimir effect in chiral media [32], and other applications [33]. Furthermore, bi-anisotropic "chiral materials", described by relations (6) involving anisotropic tensors, were employed to investigate relativistic electron gas [34], time dependent magnetoelectric parameters [35],…”

The classical propagation of electromagnetic waves in continuous matter is described by the constitutive relations and the Maxwell equations. This work investigates the effects stemming from extended constitutive relations on the propagation of waves in bi-isotropic and bi-anisotropic media using a classical general approach, based on the evaluation of dispersion relations and refractive indices. For the bi-anisotropic media, the magnetoelectric parameters were represented by specific symmetric and antisymmetric configurations. The three cases examined have provided real and distinct refractive indices for two propagating modes, which implies birefringence. The propagating modes were also carried out in all cases. The anisotropy or birefringence effect, given by the rotatory power or phase difference, was evaluated in terms of the magnetoelectric parameters of the theory in each case. The propagation orthogonal to the vectors used to parametrize the symmetric and antisymmetric magnetoelectric tensors is described by distinct modes, which may represent a route to identify the kind of bi-anisotropic medium examined.

“…reflective and transmissive properties, Fresnel formula, Brewster angle and the Goos-Hänchen effect of these materials have been studied theoretically in Refs. [30,31]. As for layered topological insulators with a time-reversal symmetry breaking perturbation, potential applications are broad, for example a waveguide that induces polarization rotations due to the magneto-electric effect and mixes the electric and magnetic induction fields at the material's surface [32].…”

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.

“…Some examples of such photon meta systems with nontrivial topological phases are hyperbolic metamaterials in the long wave length limit [6], metawaveguides and metamaterials [7][8][9][10], linear photonic systems and resonant structures [11][12][13], coupled optical [14,15] and microwave [16,17] cavity arrays or networks [18] as well as acoustical systems [19,20] and circuits [21]. Properties of such materials regardless of their particular realisations have been also studied [22][23][24][25].…”

Using full 3D finite element simulation and underlining Hamiltonian models, we demonstrate reconfigurable photonic analogues of topological insulators on a regular lattice of tunable posts in a re-entrant 3D lumped element type system. The tunability allows dynamical in-situ change of media chirality and other properties via alteration of the same parameter for all posts, and as a result, great flexibility in choice of bulk/edge configurations. Additionally, one way photon transport without an external magnetic field is demonstrated. The ideas are illustrated by using both full finite element simulation as well as simplified harmonic oscillator models. Dynamical reconfigurability of the proposed systems paves the way to a new class of systems that can be employed for random access, topological signal processing and sensing.
