  • The electron spin as a chiral reagent. [Journal Article]
    Angew Chem Int Ed Engl 2019Naaman R, Metzger TS, … Paltiel Y
  • In contrast to the notion that enantiospecific chemical reactions require a chiral reagent molecule or catalyst, this work shows that enantioselective chemical transformations can be induced by the electron spin itself. As electrons are injected from a magnetized electrode into an adsorbed molecule, they have a distinct spin orientation relative to their velocity; i.e., they have a well-defined h…
  • Controlled creation of a singular spinor vortex by circumventing the Dirac belt trick. [Journal Article]
    Nat Commun 2019; 10(1):4772Weiss LS, Borgh MO, … Hall DS
  • Persistent topological defects and textures are particularly dramatic consequences of superfluidity. Among the most fascinating examples are the singular vortices arising from the rotational symmetry group SO(3), with surprising topological properties illustrated by Dirac's famous belt trick. Despite considerable interest, controlled preparation and detailed study of vortex lines with complex int…
  • Electronic properties of polymorphic two-dimensional layered chromium disulphide. [Journal Article]
    Nanoscale 2019Habib MR, Wang S, … Xu M
  • Two-dimensional (2D) Cr-based layered and non-layered materials such as CrI3, Cr2Ge2Te6, Cr2S3, CrSe, and CrOX (X = Cl and Br) have attracted considerable attention due to their potential application in spintronics. Despite few experimental studies, theoretical studies reported that 2D chromium dichalcogenide (CrS2) materials show unique properties such as valley polarization, piezoelectric coupl…
  • Electric Field-Enhanced Adsorption of Chiral Molecules on Ferromagnetic Substrates. [Journal Article]
    J Phys Chem B 2019Santra K, Zhang Q, … Naaman R
  • The effect of an electric field on the adsorption of oligopeptides and DNA on a ferromagnetic substrate magnetized perpendicular to the surface was investigated. The direction of the magnetic moment of the substrate defines different adsorption rates for different enantiomers and the direction of the electric field, perpendicular to the surface, defines different adsorption rates, depending on th…
  • Sensitivity Ellipsoids for Force Control of Magnetic Robots with Localization Uncertainty. [Journal Article]
    IEEE Trans Robot 2019; 35(5):1123-1135Slawinski PR, Simaan N, … Valdastri P
  • The navigation of magnetic medical robots typically relies on localizing an actuated, intracorporeal, ferromagnetic body and back-computing a necessary field and gradient that would result in a desired wrench on the device. Uncertainty in this localization degrades the precision of force transmission. Reducing applied force uncertainty may enhance tasks such as in-vivo navigation of miniature rob…
  • Probing the nanostructure and arrangement of bacterial magnetosomes by small-angle x-ray scattering. [Journal Article]
    Appl Environ Microbiol 2019Rosenfeldt S, Riese CN, … Schenk AS
  • Magnetosomes are membrane-enveloped single-domain ferromagnetic nanoparticles enabling the navigation of magnetotactic bacteria along magnetic field lines. Strict control over each step of biomineralization generates particles of high crystallinity, strong magnetization and remarkable uniformity in size and shape, particularly interesting for many biomedical and biotechnological applications. How…
  • Fermi-arc diversity on surface terminations of the magnetic Weyl semimetal Co3Sn2S2. [Journal Article]
    Science 2019; 365(6459):1286-1291Morali N, Batabyal R, … Beidenkopf H
  • Bulk-surface correspondence in Weyl semimetals ensures the formation of topological "Fermi arc" surface bands whose existence is guaranteed by bulk Weyl nodes. By investigating three distinct surface terminations of the ferromagnetic semimetal Co3Sn2S2, we verify spectroscopically its classification as a time-reversal symmetry-broken Weyl semimetal. We show that the distinct surface potentials im…
  • Magnetic Weyl semimetal phase in a Kagomé crystal. [Journal Article]
    Science 2019; 365(6459):1282-1285Liu DF, Liang AJ, … Chen YL
  • Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and have characteristic surface Fermi-arcs in their electronic structure. Weyl semimetals with broken time reversal symmetry are difficult to identify unambiguously. In this work, using angle-resolved photoemission spectroscopy, we visualized the electronic structure of the ferromagnetic crystal Co3Sn2S2 and disc…
