Wavelength-scale lasers provide promising applications through low power consumption requiring for optical cavities with increased quality factors. Cavity radiative losses can be suppressed strongly in the regime of optical bound states in the continuum;

Bound states in the continuum (BICs) garnered significant research interest in the field of sensors due to their exceptionally high-quality factors. However, the wide-band continuum in BICs are noise to the bound states, and it is difficult to control and filter. Therefore, we constructed a ...
Solutions to the DLCQ bound state equations are obtained for K=2,3,...,6 by discretizing the light-cone supercharges, which results in a supersymmetric spectrum. Our numerical results imply the existence of normalizable massless states in the continuum limit K -> infinity, and therefore the...
The transverse direction is discussed as a model for universal extra dimensions in the gauge sector. The wave functions are used to calculate the structure functions of the lowest mass states. We discuss the properties of Kaluza-Klein states and focus on how they appear at strong coupling. We ...

Chain Chomps are common enemies in the Super Mario franchise. Chain Chomps were initially conceived for the The Legend of Zelda series, but a developer came across old concept art and decided to implement them in Super Mario Bros. 3. Chain Chomps...
(d) The imaginary part of Mij gives the Chern number C. The positivite semidefiniteness of Mij leads to the bound DsZ|C| on the superfluid weight. The density of states at the Fermi energy n0(EF) is maximal for vanishing bandwidth and so is the critical temperature. In this limit, ...
It’s the 30th Anniversary! Many fans have heard that Christopher Reeve made only one appearance at a science-fiction/superhero type of convention in the United States during his life…that convention was Dixie Trek in Atlanta, Georgia, on May 14, 1994. ...
The best replacement structures to design of small optical devices that have low dissipation are all-dielectric MMs12,13. These are artificial dielectric structures in the form of periodic arrays in which each unit cell contributes to the functionality of the structure. The occurrence of Mie resonan...
