چکیده
Understanding vanishing transmission in Fano resonances quantum systems and metamaterials, ultralow disordered media is key to elucidating optical interactions. Using analytic theory numerical simulations, we discover the topological structure motion under deformation of zeros complex energy plane. We demonstrate can be controlled create ultranarrow Lorentzian lines spectra time diverging rates frequency change as they converge. This suggests a new approach ultrasensitive detection.

Topological Insulators with Inversion Symmetry
Topological insulators are materials with a bulk excitation gap generated by the spin-orbit interaction that are different from conventional insulators. This distinction is characterized by Z2 topological invariants, which characterize the ground state. In two dimensions, there is a single Z2 invariant that distinguishes the ordinary insulator from the quantum spin-Hall phase. In three dimensio...
متن کاملTopological mirror symmetry with fluxes
Motivated by SU(3) structure compactifications, we show explicitly how to construct half–flat topological mirrors to Calabi–Yau manifolds with NS fluxes. Units of flux are exchanged with torsion factors in the cohomology of the mirror; this is the topological complement of previous differential–geometric mirror rules. The construction modifies explicit SYZ fibrations for compact Calabi–Yaus. Th...
متن کاملSymmetry-protected topological orders in interacting bosonic systems.
Symmetry-protected topological (SPT) phases are bulk-gapped quantum phases with symmetries, which have gapless or degenerate boundary states as long as the symmetries are not broken. The SPT phases in free fermion systems, such as topological insulators, can be classified; however, it is not known what SPT phases exist in general interacting systems. We present a systematic way to construct SPT...
