Once supersymmetric neutralinos χ̃0 are produced copiously at e+e− linear colliders, their characteristics can be measured with high precision. In particular, the fundamental parameters in the gaugino/higgsino sector of the minimal supersymmetric extension of the standard model (MSSM) can be analyzed. Here we focus on the determination of possible CP–odd phases of these parameters. To that end, ...

We study the statistics of the spacing between Coulomb blockade conductance peaks in quantum dots with large dimensionless conductance g. Our starting point is the ‘‘universal Hamiltonian’’—valid in the g→` limit—which includes the charging energy, the single-electron energies ~described by random matrix theory!, and the average exchange interaction. We then calculate the magnitude of the most ...

Single crystal electron diffraction d a ta from an odd-chain trig lyceride, glycerol trihep tadecanoate, are compared w ith the known structure o f the even-chain hom o-acid triglycerides. Both class­ es o f triglycerides are found to resem ble one ano ther in chain packing: they both have the sam e chain tilt (61 °) for the /?-polymorph and, further, the o rien ta tio n o f the T|| subcell in ...

By means of density functional theory, the adsorption properties of O₂ molecule on both isolated and N-graphene supported gold clusters have been studied. The N-graphene is modeled by a C₆₅NH₂₂ cluster of finite size. The results indicate that the catalytic activity and the O₂ adsorption energies of odd-numbered Au clusters are larger than those of adjacent even-numbered ones. The O₂ molecule i...

Utilizing dispersive gate sensing (DGS), we investigate the spin-orbit field (${\mathbf{B}}_{\mathrm{SO}}$) orientation in a many-electron double quantum dot (DQD) defined an $\mathrm{In}\mathrm{Sb}$ nanowire. While characterizing interdot tunnel couplings, find measured signal depends on electron-charge occupancy, as well amplitude and of external magnetic field. The is mostly insensitive to w...

Energetic oxygen precipitation is one possible explanation for the auroral molecular hydrogen emissions observed by the Voyager ultraviolet spectrometer. These ions deposit their energy in the Jovian thermosphere by means of ionization, dissociation, excitation, and heating processes. The photochemistry of both the neutral gas and the ionosphere is altered by the influx of atomic oxygen. The au...
