Direct observation of non-fully-symmetric coherent optical phonons by femtosecond x-ray diffraction

We directly measure by femtosecond time-resolved x-ray diffraction the E-g symmetry coherent phonon excited in bismuth by a strong optical pulse. The magnitude of the E-g mode observed is 0.2 pm peak-to-peak, compared against the 2.7-pm initial displacemen ...

Topological pumping in class-D superconducting wires

Marco Gibertini

We study adiabatic pumping at a normal metal/class-D superconductor hybrid interface when superconductivity is induced through the proximity effect in a spin-orbit coupled nanowire in the presence of a tilted Zeeman field. When the induced order parameter ...

Multiscale quantum/atomistic coupling using constrained density functional theory

William Curtin

Multiscale coupling of a quantum mechanical (QM) domain to a coarser-scale material description in a larger surrounding domain should yield forces and energies in the QM domain that are the same as would be achieved in a QM simulation of the entire system. ...

Multipactor saturation in parallel-plate waveguides

Michael Mattes, Francisco Edén Sorolla Rosario

The saturation stage of a multipactor discharge is considered of interest, since it can guide towards a criterion to assess the multipactor onset. The electron cloud under multipactor regime within a parallel-plate waveguide is modeled by a thin continuous ...

Large Charge Extraction from Metallic Multifilamentary Nb3Sn Photocathode

Christoph Peter Hauri, Fernando Ardana Lamas

The current density limit for photoemission from metals was measured in an rf photogun to be below 10(9) A/m(2). We have achieved 1.6 x 10(11) A/m(2) by photofield emission from a new type of photocathode made from a metallic-composite, multifilamentary Nb ...
