Momentum tunnelling between nanoscale liquid flows
The world of nanoscales in fluidics is the frontier where the continuum of fluid mechanics meets the atomic, and even quantum, nature of matter. Wh…
Dipolar wavevector interference induces a polar skyrmion lattice in strained BiFeO3 films
Skyrmions can form regular arrangements, so-called skyrmion crystals (SkXs). A mode with multiple wavevectors q then describes the ar…
Size-driven phase evolution in ultrathin relaxor films
Relaxor ferroelectrics (relaxors) are a special class of ferroelectrics with polar nanodomains (PNDs), which present characteristics such as slim h…
Exposing hidden periodic orbits in scanning force microscopy
The nonlinear interaction between the tip of a scanning probe microscope (SPM) and a sample is manifested in the emergence of bifurcations and unst…
Discovery of giant unit-cell super-structure in the infinite-layer nickelate PrNiO2+x
The discovery of unconventional superconductivity often triggers significant interest in associated electronic and structural symmetry breaking phe…
Folded pseudochiral Fermi surface in 4Hb-TaSe2 from band hybridization with a charge density wave
Stacking of strongly-correlated 2D materials is opening the possibility to demonstrate novel electronic or magnetic ordering phenomena. In this reg…
Global self-organization of solute induced by ion irradiation in polycrystalline alloys
Most materials are brought into nonequilibrium states during processing and during their service life. Materials for nuclear and space applications…
Scanning vortex microscopy reveals thickness-dependent pinning nano-network in superconducting niobium films
The presence of quantum vortices determines the electromagnetic response of superconducting materials and devices. Controlling the motion of vortic…
