  • Understanding how local distortions affect the functional properties of high entropy materials remains an open challenge. This work found element-specific distortions beyond nearest neighbors and a flexible cationic sublattice in spinel oxides, linking mean-field magnetism to bond lengths.

  • An electron glass state usually occurs in disordered insulating systems. Here the authors report evidence of glassy dynamics of conduction electrons in an electron-doped quantum paraelectric material KTaO3, in the good metal regime, where quantum fluctuations play an important role.

  • Electron glasses offer a convenient platform for studying glassy dynamics but are typically far from the well-delocalized limit. Here, quantum paraelectric SrTiO3 is studied as an electron gas, revealing the importance of ferroelastic twin walls on glassy electrons.

  • Nature of energy dissipation processes in two dimensional superconductors at high current drives remain largely unexplored. In this study, the authors investigate this for an interfacial superconductor and find distinct behaviours across the Berezinskii Kosterlitz Thouless phase transition.

  • The metal-insulator transition is well-known phenomenon in condensed-matter physics but the mechanisms driving the insulating state can vary from system to system and so understanding the underlying physics is complex. Here, the authors investigate electronic structure of single crystalline, Ca-doped NdNiO3 using synchrotron measurements and DFT calculations, illuminating the importance of bond disproportionation in the observed properties.
