“…Thus, in the strong coupling regime, both the emission and absorption lines distort the plasmon resonance greatly due to the Rabi splitting, which reveals the broken phase of parity-time symmetry and produces exceptional points at the loss-gain compensation frequencies. [67,79] It should be pointed out that in the strong coupling limit, the photonic and excitonic subsystems cannot be treated as separate entities, as they form new polaronic eigenstates with both light and matter characteristics.…”

Since the concept of surface plasmon amplification by stimulated emission of radiation (SPASER) was proposed in 2003, great progresses have been made on two kinds of plasmonic nanolasers, namely SPASER device and SPASER nanoparticle. In comparison, SPASER nanoparticle, with ultra‐narrow emission line, small size, and good biocompatibility, is a kind of promising luminescent nanoprobe and has a bright application prospect in biomedical imaging and sensing. Hence, it is gradually becoming an attractive research hotspot in the world. However, as the research on SPASER nanoparticle is still in its infancy, there are still lots of problems to be solved before it is widely applied. In this paper, the latest research advances of SPASER nanoparticles and their biological applications are reviewed. Besides existing problems, challenges and opportunities of SPASER nanoparticles as next generation luminescent nanoprobes are discussed as well.

Photoluminescence including fluorescence plays a great role in a wide variety of applications from biomedical sensing and imaging to optoelectronics. Therefore, the enhancement and control of photoluminescence has immense impact on both fundamental scientific research and aforementioned applications. Among various nanophotonic schemes and nanostructures to enhance the photoluminescence, we focus on a certain type of nanostructures, hyperbolic metamaterials (HMMs). HMMs are highly anisotropic metamaterials, which produce intense localized electric fields. Therefore, HMMs naturally boost photoluminescence from dye molecules, quantum dots, nitrogen-vacancy centers in diamonds, perovskites and transition metal dichalcogenides. We provide an overview of various configurations of HMMs, including metal-dielectric multilayers, trenches, metallic nanowires, and cavity structures fabricated with the use of noble metals, transparent conductive oxides, and refractory metals as plasmonic elements. We also discuss lasing action realized with HMMs.

“…The existence of Exceptional Points have been demonstrated both experimentally and theoretically in many physical contexts such as optically generated non-Hermitian photonic lattices 64 , fiber-coupled whispering-gallery-mode (WGM) resonators 49,65 , metamaterials 66 , quantum fluids 67 , electronic circuits 68 , acoustic systems 69 , etc. Thus, there is a wide range of physical platforms that can be used to realize the proposed dark matter detection schemes.…”

It is demonstrated that detection of putative particles such as paraphotons and axions constituting the dark sector of the universe can be reduced to detection of extremely weak links or couplings between cavities and modes. This method allows utilisation of extremely sensitive frequency metrology methods that are not limited by traditional requirements on ultra low temperatures, strong magnetic fields and sophisticated superconducting technology. We show that exceptional points in the eigenmode structure of coupled modes may be used to boost the sensitivity of dark matter mediated weak links. We find observables that are proportional to fractional powers of fundamental coupling constants. Particularly, in the case of axion detection, it is demonstrated that resonance frequency scaling with ∼ g aγγ θ and ∼ 3 g aγγ θ dependencies can be realised in a ternary photonic cavity system, which is beneficial as these coupling constants are extremely small. arXiv:1809.07723v2 [hep-ex]
