“…It can have a variety of physical origins such as structured bath spectral densities, strong system-bath couplings, low temperatures, or initial system-bath correlations among others [8,9,[11][12][13][14]. Delay-induced non-Markovian dynamics has been previously studied in the context of the spontaneous emission of single atoms [4,15,[17][18][19][20][21][22][23], bound states in continuum (BIC) of the EM field [24][25][26][27], and entanglement generation in emitters coupled to waveguides [4,28]. The effects of non-Markovianity have also been investigated in collective atomic states in the context of structured reservoirs [29][30][31][32][33] and in the strongcoupling regime [34].…”

We study the collective radiative decay of a system of two two-level emitters coupled to a onedimensional waveguide in a regime where their separation is comparable to the coherence length of a spontaneously emitted photon. The electromagnetic field propagating in the cavity-like geometry formed by the emitters exerts a retarded backaction on the system leading to strongly non-Markovian dynamics. The collective spontaneous emission rate of the emitters exhibits an enhancement or inhibition beyond the usual Dicke super-and sub-radiance due to a self-consistent coherent timedelayed feedback. arXiv:1907.12017v1 [quant-ph]

“…In photonic metastructures realm, this type of Fano or toroidal resonances has been categorized as high-Q quasi-BICs (Q-BIC). Augmentation of optical nonlinearities, [416][417][418] light guiding, [419] beam shaping, [420] quantum photonics, [421] and sensing and imaging [422,423] are some of important use cases of Q-BIC resonant metastructures. In Figure 15, sketches of several types of recently proposed Q-BIC metamaterials and resonators are demonstrated.…”

Biosensors have been designed and developed for detecting biomarkers, biomolecules, proteins, enzymes, organisms, and various types of bacterial and viral diseases since the turn of the century. Initially marred by poor sensitivity, specificity, and selectivity, the advent of the notion of photonic biosensors has successfully addressed such drawbacks. One of the hallmarks of modern pharmaceutical industries is the miniaturization of photonic platforms via continuous scaling down of their sizes, which was accomplished by leveraging the concept of artificial media. Numerous forms of photonic and plasmonic devices have been configured for next-generation technologies since the emergence of metamaterials. Among diverse applications, the development of cost-effective, label-free, selective, precise, and on-chip immunobiosensors with rapid sample-to-result feature has received copious interest, recently. This focused Review brings clarity to the rapidly growing body of available and in-development metamaterials-enabled diagnostic instruments based on inventive and promising approaches. Through centering on the operating principles of plasmonic, photonic, and hybrid metasensors, we mechanistically characterize and describe the properties of such tools and summarize the most recent achievements in devising metasensors and bioimaging tools with high precision. This insightful understanding serves as a comprehensive source for scientists, physicians, and students to construct ultradense and high-throughput clinical screening metadevices.

“…Specifically, we highlight a connection between multidimensional lattices and linear chains and show that this connection can be used to compute the collective decay rates of multidimensional networks. We study collective phenomena such as super-and subradiance [11,[32][33][34] and bound states in continuum (BICs) [35,36] in these multidimensional systems [37]. In our investigations, we discover the concept of multidimensional superradiance, where, unlike the well-known phenomenon discussed by Dicke [38], superradiance becomes partitioned for these multidimensional networks.…”

We study the collective decay rates of multidimensional quantum networks in which one-dimensional waveguides form an intersecting hyperrectangular lattice, with qubits located at the lattice points. We introduce and motivate the dimensional reduction of poles (DRoP) conjecture, which identifies all collective decay rates of such networks via a connection to waveguides with a one-dimensional topology (e.g., a linear chain of qubits). Using DRoP, we consider many-body effects such as superradiance, subradiance, and bound states in continuum in multidimensional quantum networks. We find that, unlike one-dimensional linear chains, multidimensional quantum networks have superradiance in distinct levels, which we call multidimensional superradiance. Furthermore, we generalize the N −3 scaling of subradiance in a linear chain to d-dimensional networks.
