Degenerate bound states in the continuum in square and triangular open acoustic resonators
Almas Sadreev, Evgeny Bulgakov, Artem Pilipchuk +2
We consider square and equilateral triangular open acoustic resonators with the and symmetries, respectively. There is an unique property of square and triangular…

Gate controlled resonant widths in double-bend waveguides: Bound states in the continuum
Almas F. Sadreev, Dmitrii N. Maksimov, Artem S. Pilipchuk
We consider quantum transmission through double-bend - and -shaped waveguides controlled by the finger gate potential. Using the effective non-Hermitian Hamiltonian approach…
