Condensed-matter physics

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three-dimensional lattice, such as diamond, and amorphous materials in which atomic position is more irregular, like in glass.

    Designing efficient nanowire chip-based electrical and optical devices remains a challenge. Here, the authors present an axial p-n junction GaAs nanowire X-ray detector that enables achieving a spatial resolution of 200 nm; probing the internal electrical field and observing hot electron effects at the nanoscale.

    Thin films of complex oxides can be grown and transferred on substrates, which provides opportunities for their manipulation, characterization and potential applications. Here, the authors fabricate and characterize nanodrum resonators of suspended thin single-crystal complex oxides and investigate the temperature dependent properties and associated phase transitions of the isolated ultrathin form.

    Spin angular momenta play a crucial role in topological phases of matter, in acoustic waves they have been demonstrated recently. Here, the authors present a symmetry-breaking metasurface waveguide that assists backscattering suppression of acoustic waves, because of tight spin-momentum coupling.

    Topologically trivial and Majorana bound states can show spectral weight near the ends of a chain of magnetic atoms on a superconductor. Here, the authors disentangle the two contributions by augmenting a spin chain with orbitally-compatible nonmagnetic atoms, where a persistent zero-energy spectral weight at the transition between the two parts is observed.

    Topological spin textures such as merons are attractive for technological applications due to their inherent stability; however, materials exhibiting them are limited. Here, using a mix of theoretical approaches, the authors propose chromium triiodide as a possible candidate for hosting merons.

    Progress towards low-power electronics based on negative capacitance has been slow. For the field to develop, the gap between fundamental research on ferroelectric materials and the engineering of practical devices needs to be bridged.

    Volumes of fluid have previously been made to float above air by vibrating the air–fluid system vertically. It now emerges that an ‘antigravity’ effect enables objects to float upside down on the air–fluid interface.

    The photovoltaics market has long been dominated by silicon, but further improvements of these solar cells require novel approaches. Now, triplet–triplet annihilation photon upconversion has been used to harvest photons from below the bandgap of silicon, extending the spectral response and potentially improving the efficiency of these cells.
