]]>Transmission electron microscopy has been a promising candidate for mapping atomic orbitals for a long time. Here, we explore its capabilities by a first-principles approach. For the example of defected graphene, exhibiting either an isolated vacancy or a substitutional nitrogen atom, we show that t…

]]>Three-dimensional linear spin-wave eigenmodes of a vortex-state Permalloy disk are studied by micromagnetic simulations based on the Landau-Lifshitz-Gilbert equation. The simulations confirm that the increase of the disk thickness leads to the appearance of additional exchange-dominated so-called gy…

]]>The metal-to-insulator transition in ${\mathrm{BaTiO}}_{3}$ is investigated using electrostatic doping, which avoids effects from disorder and strain that would accompany chemical doping. ${\mathrm{SmTiO}}_{3}/{\mathrm{BaTiO}}_{3}/{\mathrm{SrTiO}}_{3}$ heterostructures are doped with a constant sheet carrier density of $3\times {10}^{14}\text{\hspace{0.17em}}\text{\hspace{0.17em}}{\mathrm{cm}}^{-2}$ that is introduced via the…

The critical criterion in a threshold secret sharing scheme is confidentiality: with less than the …

]]>The temperature-pressure phase diagram of the ferromagnet ${\mathrm{LaCrGe}}_{3}$ is determined for the first time from a combination of magnetization, muon-spin-rotation, and electrical resistivity measurements. The ferromagnetic phase is suppressed near 2.1 GPa, but quantum criticality is avoided by the appearanc…

Our work reveals an interacting network of strongly nonlinear dynamical nodes, on which even a simple sound input triggers subnetworks of activated elements that follow …

]]>A continuous quantum field, such as a propagating beam of light, may be characterized by a squeezing spectrum that is inhomogeneous in frequency. We point out that homodyne detectors, which are commonly employed to detect quantum squeezing, are blind to squeezing spectra in which the correlation bet…

When the corresponding equation of state (EOS) is matched with state-of-the-art results for dense nuclear matter, we consistently observe a first-order phase transition at densities be…
