Summary: The study successfully measured and observed phonon polaritons in monolayer hexagonal boron nitride using monochromatic electron energy-loss spectroscopy, revealing highly confined and ultraslow group velocity characteristics. The large momentum compensation provided by electron beams also enabled phonon polariton excitation over the entire Reststrahlen band of multilayer hexagonal boron nitride.

Summary: This study investigates the magneto-optical rotation of surface plasmon polaritons at the interface of a metal and a four-level atomic system, finding that the external magnetic field plays a vital role in controlling the magneto-optical rotation. When the magnetic field or the probe field is tuned to resonance, the magneto-optical rotation stops completely.

Summary: In analogy to Lifshitz transitions in electronic systems, topological transitions have recently attracted attention in photonics, enabling exotic regimes for light-matter interactions. This study explores enhanced photonic local density of states in twisted hyperbolic bilayers, highlighting the potential applications of topological transitions in photonics for manipulating radiative heat transfer and controlling light at the nanoscale.

Summary: This study proposes an ultra-thin and electric tunable graphene/hexagonal boron nitride/graphene metasurface for detecting molecular fingerprints. The metasurface supports hybrid plasmon-phonon polariton resonance with high-quality factor and can achieve tunability over a broad spectrum. This method enables broadband fingerprint retrieval of bio-molecules and paves the way for highly sensitive, miniaturized, and electrically addressed biosensing and infrared spectroscopy.

Summary: This article reviews and compares the optical properties of metallic nanoparticles and nanovoids, which are capable of generating and controlling plasmon resonances. These systems can concentrate and manipulate fields at the nanometer scale, making them attractive building blocks for emerging applications. Metal particles and nanovoids exhibit different plasmonic modes, dependent on factors such as size, shape, and material properties. Specific geometrical features, like the presence of rims in nanovoids, make them promising structures for designing exotic band spectra due to the coupling between different resonant modes.

Summary: This study obtains the equivalent permittivity distribution of 2D heterostructures using the effective medium theory and analyzes the rotation-induced topological transitions and stack-dependent topological transitions of phonon polaritons. The topological transition points can be predicted by a parameter epsilon x/y, and the phonon polaritons in stacked materials can be precisely designed by controlling the equivalent permittivity. The feasibility of the effective medium theory is verified and the field distributions and dispersions of the 2D heterostructures are compared with the corresponding equivalent structure. The study provides a simpler and clearer criterion for the study of photonic topological transition in anisotropic polaritons and shows great potential in designing multilayer 2D heterostructures.

Summary: This study successfully captures and analyzes the properties and dispersion of plasmon polaritons in thin Bi2Se3 layers using THz near-field imaging technique. The results show that the momentum and decay time of polaritons significantly increase compared to photons, but the propagation length is short. The study further reveals the coupling process between THz radiation and Dirac and Massive carriers on the surface of topological insulators and carriers and photons in the bulk.

Summary: This paper theoretically investigates real-space anisotropic plasmons in WTe2 thin films. The study demonstrates anisotropic near-field plasmonic images with specific interference patterns and isofrequency curves in momentum space. The research reveals a topological transition from elliptic to hyperbolic regime due to the frequency selective forbidden of plasmons along the b axis, and the plasmons and topological transition display significant electrostatic-gating tunability.

Summary: The strong coupling between excitons in few-layer transition-metal dichalcogenide (TMDC) and guided mode resonance (GMR) or bound state in the continuum (BIC) is investigated. The results show that a large Rabi splitting can be achieved by changing the grating period, reaching up to 155 meV or 162 meV, respectively. The physical origins behind this behavior are revealed through studying the electric field distributions at resonance and theoretical verification according to the coupled-oscillator model. The effect of geometric dimensions on the strong coupling is also studied, offering guidance for real fabrication and paving the way for novel, compact TMDC-based polaritonic devices.

Summary: The study demonstrates the direct observation of the plasmonic Doppler effect in biased monolayer graphene, showing a non-reciprocal plasmon propagation due to fast drifting Dirac electron medium hosting the plasmon polariton. Cryogenic near-field infrared nanoscopy was used to measure the Doppler-shifted plasmon wavelength, showing a significant difference between plasmons moving with and against the drifting electron media. These findings open up opportunities for electrical control of non-reciprocal surface plasmon polaritons in non-equilibrium systems.

Summary: Conditions defining the spectral location of bandgaps in the quasi-transverse magnetic surface plasmon polariton modal dispersion for 2D/quasi-2D materials with a tensor response function embedded in a simple isotropic medium are obtained. In the isotropic case, transverse magnetic surface plasmon polariton modes propagate with an inductive surface conductivity. However, in the anisotropic case, quasi-transverse magnetic modes are supported by surfaces with an inductive effective conductivity along the direction of propagation. Examples of natural anisotropic 2D/quasi-2D materials are provided to demonstrate the effectiveness of the method.

Summary: The report investigates the statistical temporal distribution of nonlinear upconverted photoluminescence emitted by gold and silver nanostructures excited by focused near-infrared laser pulses. Regardless of the nano-object's geometry, material's crystalline arrangement, and electronic band structure, a clear signature of photon bunching is systematically observed. The correlation of photons at a picosecond time scale released by nanoscale nonlinear sources of broadband radiation may be used in developing new data processing functionalities in plasmonic devices.

Summary: This research demonstrates that plasmonic nanowire-nanoparticle systems can perform nonlinear wavelength and modal conversions, potentially serving as building blocks for signal multiplexing and novel trafficking modalities.The generation of a localized broadband nonlinear continuum in the nanowire surface as well as at active locations defined by sites where nanoparticles are absorbed may couple to new sets of propagating modes enabling a complex routing of optical signals through modal and spectral conversions. Various aspects influencing the optical signal conversions are presented, including parameters defining the local formation of the continuum and the subsequent modal routing in the nanowire.
