Kavli Affiliate: Edmund Bertschinger | Summary:Initiatives to increase the number, persistence, and success of women in physics in the US reach pre-teen girls through senior women. Programs exist at both the local and national levels. In addition, researchers have investigated issues related to gender equity in physics and physics education. Anecdotal evidence suggests increased media […]
Kavli Affiliate: Miriam Blaauboer | Summary:We theoretically investigate the effect of transverse magnetic anisotropy on spin-flip assisted tunneling through atomic spin chains. Using a phenomenological approach and first-order perturbation theory, we analytically calculate the inelastic tunneling current, differential conductance and atomic spin transition rates. We predict the appearance of additional steps in the differential conductance […]
Kavli Affiliate: Dustin M. Schroeder | Summary:We estimate the sensitivity of a lander-based instrument for the passive radio detection of a subsurface ocean beneath the ice shell of Europa, expected to be between 3~km – 30~km thick, using Jupiter’s decametric radiation. A passive technique was previously studied for an orbiter. Using passive detection in a […]
Kavli Affiliate: Maria T. Zuber | Summary:Previous observations suggested that Ceres has active but possibly sporadic water outgassing, and possibly varying spectral characteristics in a time scale of months. We used all available data of Ceres collected in the past three decades from the ground and the Hubble Space Telescope, and the newly acquired images […]
Kavli Affiliate: Hiraku Nakajima | Summary:Consider the $3$-dimensional $mathcal N=4$ supersymmetric gauge theory associated with a compact Lie group $G_c$ and its quaternionic representation $mathbf M$. Physicists study its Coulomb branch, which is a noncompact hyper-Kähler manifold with an $mathrmSU(2)$-action, possibly with singularities. We give a mathematical definition of the Coulomb branch as an affine […]
Kavli Affiliate: Julia R. Greer | Summary:The atomic-level structures of liquids and glasses are amorphous, lacking long-range order. We characterize the atomic structures by integrating radial distribution functions (RDF) from molecular dynamics (MD) simulations for several metallic liquids and glasses: Cu46Zr54, Ni80Al20, Ni33.3Zr66.7, and Pd82Si18. Resulting cumulative coordination numbers (CN) show that metallic liquids have […]
