A bound state in the continuum (BIC) is a localized state of an open structure with access to radiation channels, yet it remains highly confined with, in theory, an infinite lifetime and quality factor. There have been many realizations of such exceptional states in dielectric systems without ...
Chen, Formation mechanism of guided resonances and bound states in the continuum in photonic crystal slabs 6, 31908 (2016).Gao, X.; Hsu, C. W.; Zhen, B.; Lin, X.; Joannopoulos, J. D.; Soljacǐ c,́ M.; Chen, H. Formation mechanism of guided resonances and bound states in...
We develop a formalism, based on the mode expansion method, to describe the guided resonances and bound states in the continuum (BICs) in photonic crystal slabs with one-dimensional periodicity. This approach provides analytic insights to the formation mechanisms of these states: the guided resonance...
In QPCs with a highly asymmetric geometry, we observe sharp resonance peaks when the point contacts are gated to the single mode regime, and surprisingly, under certain gating conditions, a complete destruction of the 2e/h first quantum plateau. The temperature evolution of the resonances suggest...
Generally, bound states in the continuum are rare and very fragile, and their stability relies on integrability or symmetries28,29. Familiar stable dimers, such as excitons in semiconductors, have energy resonances in the spectral gap. In the system considered here, the bound states are predicted...
in details. We applied continuum elasticity theory to obtain continuous trajectory of pore formation and closure, and analyzed molecular dynamics trajectories of pre-formed pore reseal. We hypothesized that a transversal pore is preceded by a hydrophobic defect: intermediate structure spanning through the...
Chloramine leads to a significant decrease in the THM and HAA levels; because of this, it is popular in many countries, such as the United States. However, chloramine also has its drawbacks. In particular, it increases the level of highly carcinogenic N-dimethylnitrosamine and results in the ...
We have used density-functional theory combined with solvent continuum models to confirm first, the nature of the reactants, an aluminium hydroxide dimer and silicic acid, second, the reaction products, two distinct hydroxyaluminosilicates A and B and finally, how these are the precursors to ...
Novel continuum model for lithium plating and dendrite formation presented. • Discerns irreversible vs. reversible plating. • Discerns dangerous live dendrites vs. dead/inert Li. • Cogent explanation for dead lithium formation is offered. • Comparison with state-of-the-art experimental data...
The formation of hydroxyaluminosilicates is integral to the biogeochemical cycles of aluminium and silicon. The unique inorganic chemistry which underlies their formation explains the non-essentiality in biota of both of these elements. However, the firs
