  • Non-reciprocal frequency conversion in a non-Hermitian multimode nonlinear system

    Non-reciprocal frequency conversion in a non-Hermitian multimode nonlinear system

    Theory and system description

    The system under consideration is depicted in Fig. 1a, representing a multimodal nonlinear cavity that supports cascaded three-wave mixing processes mediated by a common idler bath mode at frequency ωT. A pump mode…

  • Entanglement distribution in lossy quantum networks

    Entanglement distribution in lossy quantum networks

    We consider an N-partite network that is served by a centralized source that generates and then distributes an N-qubit state (resource) \(\psi\) to the network participants. The links from the source to each node are assumed to be lossy, i.e., a…

  • Revealing the mechanisms of non-thermal plasma-enabled iron oxide reduction through nanoscale operando TEM

    Revealing the mechanisms of non-thermal plasma-enabled iron oxide reduction through nanoscale operando TEM

    The direct reduction of magnetite to iron by H2 can be expressed as:

    $${{\rm{F}}}{{{\rm{e}}}}_{3}{{{\rm{O}}}}_{4}+4{{{\rm{H}}}}_{2}\to 3{{\rm{Fe}}}+4{{{\rm{H}}}}_{2}{{\rm{O}}}.$$

  • Coherent control of anisotropic SPPs in a symmetric double-layer metal/uniaxial dielectric structure

    Coherent control of anisotropic SPPs in a symmetric double-layer metal/uniaxial dielectric structure

    This section contains our outcomes. We find the dispersion relation of SPPs, wavelength, propagation length, and reflection and transmission coefficients (by using the scattering matrix) for a symmetric double-layer metal/uniaxial dielectric…

    Efficient fibre-pigtailed source of indistinguishable single photons

    Source design and fibre coupling

    Our quantum emitters are annealed self-assembled InGaAs QDs grown by molecular beam epitaxy positioned at the centre of an unbalanced GaAs planar microcavity formed from 20(40)-pairs top (bottom) distributed Bragg…

  • Particulate reshapes surface jet dynamics induced by a cavitation bubble

    Particulate reshapes surface jet dynamics induced by a cavitation bubble

    Characteristics of the five jet modes

    We use underwater spark bubbles to drive jet formations on the water surface and employ floating solid spheres to create surface defects (Fig. 1a and ‘Methods’). Figure 1b outlines the key geometric…
