An increasing prevalence of antibiotic-resistant foodborne infections has resulted in considerable concern about how antimicrobials are used in meat and poultry production. Because many foodborne bacterial pathogens are commonly found among the intestinal bacterial community of poultry, new methods of prevention are being considered. Bacteriophage therapy(More)
The conductance profiles of magnetic transition-metal atoms, such as Fe, Co, and Mn, deposited on surfaces and probed by a scanning tunneling microscope (STM), provide detailed information on the magnetic excitations of such nanomagnets. In general, the profiles are symmetric with respect to the applied bias. However, a set of recent experiments has shown(More)
Recent experimental advances in scanning tunneling microscopy make the measurement of the conductance spectra of isolated and magnetically coupled atoms on nonmagnetic substrates possible. Notably, these spectra are characterized by a competition between the Kondo effect and spin-flip inelastic electron tunneling. In particular they include Kondo resonances(More)
We demonstrate that a quantum spin Hall current, spontaneously generated at the edge of a two-dimensional topological insulator, acts as a source of spin pumping for a magnetic impurity with uniaxial anisotropy. One can then manipulate the impurity spin direction by means of an electrical current without using either magnetic electrodes or an external(More)
We present a theoretical study of the spin transport properties of monoatomic magnetic chains with a focus on the spectroscopical features of the I -V curve associated with spin-flip processes. Our calculations are based on the s-d model for magnetism with the electron transport treated at the level of the nonequilibrium Green’s function formalism.(More)
