Exceptional-Point Geometry of Weak Topological Boundary States
Rafael A. Molina, Kevin González, Pedro A. Orellana
In this article, we demonstrate that weak topology can be formulated geometrically in terms of exceptional singularities of an analytically continued Bloch Hamiltonian. A general p…

Bound States in the Continuum in a Double Whispering Gallery Resonator
Alexis R. Legón, M. Ahumada, J. P. Ramos-Andrade +2
In this work, we investigate the single-photon transport through two whispering gallery resonators (WGRs) coupled to a one-dimensional waveguide. Using Green's function formalism,…

Beyond symmetry-protected BICs: transmission through asymmetric crossbar junctions in one-dimensional waveguides
Sofía Pinto, Rafael A. Molina, Pedro A. Orellana
Over the last few decades, the study of Bound States in the Continuum, their formation, and properties has attracted lots of attention, especially in optics and photonics. It is pa…
