Massive amplitudes on the Coulomb branch of N=4 SYM

open access: yes, 2011
We initiate a systematic study of amplitudes with massive external particles on the Coulomb-branch of N=4 super Yang Mills theory: 1) We propose that (multi-)soft-scalar limits of massless amplitudes at the origin of moduli space can be used to determine

The growth of bismuth on Bi$_2$Se$_3$ and the stability of the first bilayer

open access: yes, 2018
Bi(0001) films with thicknesses up to several bilayers (BLs) are grown on Se-terminated Bi$_2$Se$_3$(0001) surfaces, and low energy electron diffraction (LEED), low energy ion scattering (LEIS) and atomic force microscopy (AFM) are used to investigate ...

Surface friction of rock in terrestrial and simulated lunar environments [PDF]

open access: yes
The conventional probe-on-the rotating-disk concept was used to determine the surface friction in mineral probe/specimen interfaces. Nine rocks or minerals and two stainless steels were tested in both new (NT) and same track (ST) tests under three ...
