We study the scattering properties of arrays of core-shell nanoparticles and reveal the existence of polarizationindependent Fano resonances. Such Fano resonances occur through the interaction of a pair of degenerate orthogonal electric and artificial magnetic modes of the same strength with the spectrally narrow geometric resonance due to the diffractive coupling in the array. Furthermore, we ...

Fano resonances in plasmonic systems have been proved to facilitate various sensing applications in the nanoscale. In this work, we propose an experimental scheme to realize a single protein sensing by utilizing its two-photon luminescence enhanced by a plasmonic Fano resonance system. The asymmetric gold hexamer supporting polarization-dependent Fano resonances and plasmonic modes without in-p...

We reveal that asymmetric plasmonic nanostructures can exhibit significantly different absorption and scattering properties for light that propagates in opposite directions, despite the conservation of total extinction. We analytically demonstrate that this is a consequence of nonorthogonality of eigenmodes of the system. This results in the necessity for modal interference with potential enhan...

Fano resonance with electron doping for the in-plane Raman mode near 151 cm?1 in ReS2.

We report on an eKcient numerical technique for directly locating transmission resonances and zeros in semiconductor heterostructures using tight-binding multiband models. The quantum transmitting boundary method is employed to generate the inverse of the retarded Green's function G (E) in. the tight-binding representation. The poles of G (E) are located. by solving a nonlinear non-Hermitian ei...

We investigate Fano-type anomalous transmission of energy of plane waves across lossless slab scatterers with periodic structure in the presence of non-robust guided modes. Our approach is based on rigorous analytic perturbation of the scattering problem near a guided mode and applies to very general structures, continuous and discrete.

In quantum information theory, it is well known that the tripartite entanglement of three qubits is described by the group SL 2; C 3 and that the entanglement measure is given by Cayley’s hyperdeterminant. This has provided an analogy with certain N 2 supersymmetric black holes in string theory, whose entropy is also given by the hyperdeterminant. In this paper, we extend the analogy to N 8. We...
