## Description

- description: "We present a detailed theoretical analysis of a peculiar generation
    of multiple bound states in the continuum\r\n(BICs) in two-dimensional periodic
    arrays of dielectric spheres. They emerge in high-symmetry lattices with the C6v
    and C4v point groups and involve doubly degenerate quasiguided modes at the Gamma
    point that can couple to external radiation. By tuning a system parameter, the
    doubly degenerate modes can exhibit accidental BICs at a critical parameter. In
    the vicinity of the critical parameter, the two bands originating from the degenerate
    mode exhibit multiple off-Gamma BICs. They move and annihilate across the two
    bands by changing the parameter around the critical one. A ring-like high-Q channel
    pinned with multiple BICs emerges particularly for the C6v case. Across the critical
    coupling, the total vorticity of the multiple BICs is conserved. The k · p perturbation
    theory explains some features of the phenomena reasonably well."
