  • The authors investigate how the disorder and the interplay of lateral and axial polarization of the polar vortex topology in SrTiO3/PbTiO3 superlattices can lead to the formation of the chiral and achiral domain walls, and subsequently the triple point topologies.

  • Recent electron microscopy techniques have attracted significant attention for their ability to image electric fields at the atomic level. Here, the authors investigate the possibility to separate the charge density contributions of core and valence electrons in monolayer MoS2, highlighting the limitations induced by the electron probe shape.

  • The polar chiral texture of the vortex or skyrmion structure in ferroelectric oxide PbTiO3/SrTiO3 superlattice attracts attention. Here, the authors report a theoretical framework to probe emergent chirality of electrical polarization textures.

  • A spin–orbit torque efficiency of around 2.7 can be achieved in heterostructures based on the bismuthate BaPb1−xBixO3, which can be used to drive magnetization switching at current densities of 4 × 105 A cm−2.

  • The response of the electronic structure to the non-trivial polarization texture in PbTiO3/SrTiO3 superlattices has not been explored. Here, the authors reveal how the peaks of the spectra shift and change their local electronic structure depending on the position of the Ti cation.
