The power of two

An optimized design for broad-area surface-emitting photonics-crystal laser leads to high brightness of over 300 MW cm−2 sr−1 and an output power of 10 W under pulsed excitation.

    Higher-order topological acoustic metamaterials on kagome lattices, which host topologically protected corner states, can confine sound at corners. This may lead to applications of acoustic metamaterials in local acoustic field enhancement, trapping and manipulating of particles, and acoustic sensing and probing.

    Despite an enormous number of nanopores that could, in principle, be formed in atomically thin materials, advanced modelling reveals that in typical experiments rather limited ensembles of most likely nanopores should be observed.
