“…It would also be advantageous if the negative index could be obtained over a range of directions for propagation of light. One of the proposed routes towards negative refractive indices is based on the use of strongly chiral media [3][4][5][6][7][8][9][10]. This may potentially lead to materials for which some of the problems encountered with metamaterials are alleviated.…”

This paper presents methodology developed for the computational modeling and design of negative refractive index materials (NIMs) based on molecular chirality. An application of the methodology is illustrated by ab initio computations on two organometallic molecules which constitute the monomer units of a chiral polymer. Comparisons with experimental data for the polymer are made. Even though the resulting chirality parameter for the pristine material is small, it is shown that negative index can be achieved by introducing sharp plasmonic resonances with metal nanoparticle inclusions.

“…In the literature, there have been some designs of nanomechanical photonic devices [21][22][23][24][25] by taking advantage of transfer of energy, momentum or angular momentum from electromagnetic fields (at both classical and quantum levels) to electromagnetic media, including time crystals [23,24], quantum wheels and "perpetuum mobile" of the third and fourth kinds [25]. All such new possible devices will exhibit motion (e.g., rotation, precession and nutation) of the electromagnetic materials.…”

Abstract-A subject of plasmonic spinphotonics is developed for surface plasmon polaritons (SPPs). Since an electromagnetic field is a vectorial field, it has spinning angular momentum, and thus spin current is one of its degrees of freedom. A spin current density tensor has 24 independent components because of its antisymmetry in coordinate indices. By using the law of conservation of electromagnetic angular momentum (i.e., orbital angular momentum plus spinning angular momentum), the electromagnetic spin current density tensor is derived, and its characteristics are indicated. Since surface plasmon polaritons can exhibit various intriguing optical and electromagnetic effects and have many practical applications, we consider a new potential effect relevant to spin current transfer. The electromagnetic spin current density tensor and its intensity profile are analyzed for SPPs sustained on a metal-dielectric interface. The plasmonic spin on a metal ring and a straight thin metal belt is calculated, and based on this, a nanomechanical effect caused by plasmonic spin current transfer is suggested. It is expected that such a nontrivial nanomechanical effect will be useful in the design of new nanophotonic devices aiming at sensitive, accurate measurement techniques.

“…Indeed, this study is written in the hope that our revised predictions will stimulate experiments to try and measure Feigel's original effect and related predictions proposed recently. Since the publication of Feigel's result, several theoretical works have emerged, which have been very enthusiastic about Feigel's idea (van Tiggelen et al 2005(van Tiggelen et al , 2006Shen et al 2006;Birkeland & Brevik 2007;Obukhov & Hehl 2008). Some have, however, questioned the soundness of the original argument stating that no unbounded macroscopic Feigel effect should exist if proper regularization is applied to the momentum integral (van Tiggelen et al 2005(van Tiggelen et al , 2006.…”

“…Microscopically, however, recent work suggests that a properly regularised Feigel effect could exist (Kawka et al 2010). Most other alternative macroscopic theories consider the momentum from the vacuum for magnetoelectric fluids (Birkeland & Brevik 2007) and samples of magnetoelectric materials ( van Tiggelen et al 2006) confined in parallel plate geometries, like in the Casimir effect. The latter work predicts an unmeasurably small linear momentum transfer ( van Tiggelen et al 2006).…”

A recent theory by Feigel predicts the finite transfer of momentum from a quantum vacuum to a fluid placed in strong perpendicular electrical and magnetic fields. The momentum transfer arises because of the optically anisotropic magnetoelectric response induced in the fluid by the fields. After summarizing Feigel's original assumptions and derivation (corrected of trivial mistakes), we rederive the same result by a simpler route, validating Feigel's semiclassical approach. We then derive the stress exerted by the vacuum on the fluid that, if the Feigel hypothesis is correct, should induce a Poiseuille flow in a tube with maximum speed at ≈ 100 mm s −1 (2000 times larger than Feigel's original prediction). An experiment is suggested to test this prediction for an organometallic fluid in a tube passing through the bore of a high-strength magnet. The predicted flow can be measured directly by tracking microscopy or indirectly by measuring the flow rate (≈ 1 ml min −1 ) corresponding to the Poiseuille flow. A second experiment is also proposed, whereby a 'vacuum radiometer' is used to test a recent prediction that the net force on a magnetoelectric slab in the vacuum should be zero.
