“…All kinds of photonic crys- * Ilia.Fradkin@skoltech.ru tals and metasurfaces were studied intensively for the last several decades, and their optical properties are known in much detail. In recent years there was a growth of attention to stacks of metasurfaces [29][30][31][32][33][34][35][36][37][38] due to the new opportunities that they provide for the control and manipulation of light. Simultaneously, much fewer studies considered the interaction of crystals that do not have a mutual lattice either because of the periods discrepancy or even misalignment of crystallographic axes.…”

In recent years twisted bi-layers of 2D materials became very popular in the field due to the possibility to totally change their electronic properties by simple rotation. At the same time, in the wide field of photonic crystals, this idea still remains almost untouched, and only some particular problems were considered. One of the reasons is the computational difficulty of the accurate consideration of Moiré superlattices that appear due to the superimposition of misaligned lattices. Indeed, the unit cell of the complex lattice is typically much larger than the original crystals and requires much more computational resources for the computations. Here, we propose a careful adaptation of the Fourier modal method in the form of the scattering matrices for the description of twisted 1D gratings' stacks. Our approach allows us to consider sublattices in close vicinity to each other and account for their interaction via the near-field. In the developed numerical scheme, we utilize the fact that each sublattice is only 1D-periodic and therefore simpler than the resulting 2D superlattice, as well as the fact that even a small gap between the lattices filters out high Fourier harmonics due to their evanescent origin. This accelerates the computations from 1 up to 3 and more orders of magnitude for typical structures depending on the number of harmonics. This paves the way for rigorous study of almost any photonic crystals of the proposed geometry and demonstration of specific Moiré-associated effects.

“…In this case, a majority of NPs are excited with the same phase, which results in ultra-narrow high-Q spectral features. CLRs have been well studied for nanostructures from plasmonic NPs for a long time [44][45][46][47][48][49][50][51][52][53][54][55][56], while the all-dielectric analogues have gained attention only a decade ago [57]. In contrast to plasmonic NPs (in most of the cases characterized by weak magnetic and strong electric responses), all-dielectric NPs with pronounced electric and magnetic optical resonances [58] give rise to a rich variety of tunable CLRs that emerge even in regular rectangular-shaped arrays [32].…”

Collective lattice resonances (CLRs) emerging under oblique incidence in 2D finite-size arrays of Si nanospheres have been studied with the coupled dipole model. We show that hybridization between the Mie resonances localized on a single nanoparticle and angle-dependent grating Wood–Rayleigh anomalies allows for the efficient tuning of CLRs across the visible spectrum. Complex nature of CLRs in arrays of dielectric particles with both electric dipole (ED) and magnetic dipole (MD) resonances paves a way for a selective and flexible tuning of either ED or MD CLR by an appropriate variation of the angle of incidence. The importance of the finite-size effects, which are especially pronounced for CLRs emerging for high diffraction orders under an oblique incidence has been also discussed.

“…[1,2] Plasmonic materials are widely used in applications such as water splitting, [3] photovoltaic cells, [1,[4][5][6][7] plasmon lasers, [8] chemical synthesis, [9] high-resolution imaging, [10] and biomedical and telecom applications. [11][12][13][14] LSP resonance is also actively utilized for nanoscale chemical and biological sensing. [15][16][17][18] The sensor properties are conditioned here by the high sensitivity of the surface resonant frequency (SRF) to the permittivity of the surrounding chemical environment, which leads to the frequency shifting, for example, due to chemical adsorption.…”

“…Therefore, there are a variety of different forms of plasmonic materials, such as individual NPs of different shapes and materials [20] and 2D lattices. [11][12][13]21] A presence of conductive material between two NPs leads to the emergence of a new mode, called the charge transfer plasmon (CTP), where the charge periodically moves between two NPs along a conductive bridge. For example, CTP was experimentally observed in a system consisting of two Au NPs linked by a thick gold bridge of radius %10 to 20 nm.…”

Thermoelectric and plasmonic properties of systems comprising small golden nanoparticles (NPs) linked by narrow conductive polymer bridges are studied using the original hybrid quantum‐classical model. The bridges are considered here to be either conjugated polyacetylene, polypyrrole, or polythiophene chain molecules terminated by thiol groups. The parameters required for the model are obtained using density functional theory and density functional tight‐binding simulations. Charge‐transfer plasmons in the considered dumbbell structures are found to possess frequency in the infrared region for all considered molecular linkers. The appearance of plasmon vibrations and the existence of charge flow through the conductive molecule, with manifestation of quantum properties, are confirmed using frequency‐dependent polarizability calculations implemented in the coupled perturbed Kohn–Sham method. To study the thermoelectric properties of the 1D periodical systems, a universal equation for the Seebeck coefficient is derived. The phonon part of the thermal conductivity for the periodical –NP–S–normalC8normalH8– system is calculated by the classical molecular dynamics. The thermoelectric figure of merit ZT is calculated by considering the electrical quantum conductivity of the systems in the ballistic regime. It is shown that for Au309 nanoparticles connected by polyacetylene, polypyrrole, or polythiophene chains at T = 300 K, the ZT value is {0.08;0.45;0.40}, respectively.
