Gondolo, Paolo | Dark stars: dark matter in the first stars leads to a new phase of stellar evolution | The _x000C_first phase of stellar evolution in the history of the universe may be Dark Stars, powered by dark matter heating rather than by fusion. Weakly interacting massive particles, which are their own antiparticles, can annihilate and provide an important heat source for the fi_x000C_rst stars... | Dark stars; WIMP; Weakly interacting massive particles | 2008-06 |

Boehme, Christoph | Effect of exchange coupling on coherently controlled spin-dependent transition rates | The effect of exchange interactions within spin pairs on spin-dependent transport and recombination rates through localized states in semiconductors during coherent electron-spin resonant excitation is studied theoretically. It is shown that for identical spin systems, significant quantitative diff... | Spin coherence; Electron spin nutations | 2008-06 |

Dawson, Kyle | Radiation tolerance of fully-depleted P-channel CCDs designed for the SNAP satellite | Thick, fully depleted p-channel charge-coupled devices (CCDs) have been developed at the Lawrence Berkeley National Laboratory (LBNL). These CCDs have several advantages over conventional thin, n-channel CCDs, including enhanced quantum efficiency and reduced fringing at near-infrared wavelengths an... | P-Channel CCDs; SNAP satellite; Space-based telescopes | 2008-06 |
