Non-Hermitian band theory naturally arises in active materials because energy is both consumed and dissipated, resulting in the presence of skin modes and odd viscoelasticity. The full potential of these ideas extends from the fundamental understanding of topology in non-equilibrium systems to applicatio...

Observation of tubular edge states In the tubular geometry, the topological picture changes in comparison to the sheet, in that only a discrete number of states fall into the nontrivial range of the band gap. As discussed earlier (Fig. 1), the nontrivial topological properties of the acoustic...
