Kavli Affiliate: Ali Javey | Summary:The epitaxial growth of 111 oriented Au on MoS$_2$ is well documented despite the large lattice mismatch (~8% biaxial strain), and the fact that a Au 001 orientation results in much less elastic strain. An analysis based on density functional and linear elasticity theories reveals that the 111 orientation is […]
Kavli Affiliate: Richard Berry | Summary:Recent experiments on the bacterial flagellar motor have shown that the structure of this nanomachine, which drives locomotion in a wide range of bacterial species, is more dynamic than previously believed. Specifically, the number of active torque-generating units (stators) was shown to vary across applied loads. This finding invalidates the […]
Kavli Affiliate: Christopher Ober| First 5 Authors: F. Ober, F. Ober, , , | Summary:Circumstellar disks are considered to be the birthplace of planets. Specific structures like spiral arms, gaps, and cavities are characteristic indicators of planet-disk interaction. Investigating these structures can provide insights into the growth of protoplanets and the physical properties of the […]
Kavli Affiliate: Patricia Burchat | Summary:Wavelength-dependent point spread functions (PSFs) violate an implicit assumption in current galaxy shape measurement algorithms that deconvolve the PSF measured from stars (which have stellar spectral energy distributions (SEDs)) from images of galaxies (which have galactic SEDs). Since the absorption length of silicon depends on wavelength, CCDs are a potential […]
Kavli Affiliate: Daniel Ralph| First 5 Authors: William Ralph, William Ralph, , , | Summary:Occam’s Razor tells us to pick the simplest model that fits our observations. In order to make sense of his process mathematically, we interpret it in the context of posets of functions. Our approach leads to some unusual new combinatorial problems […]
Kavli Affiliate: Hiroaki Aihara | Summary:We present properties of moderately massive clusters of galaxies detected by the newly developed Hyper Suprime-Cam on the Subaru telescope using weak gravitational lensing. Eight peaks exceeding a S/N ratio of 4.5 are identified on the convergence S/N map of a 2.3 square degree field observed during the early commissioning […]
Kavli Affiliate: Blas Cabrera | Summary:CDMS II data from the 5-tower runs at the Soudan Underground Laboratory were reprocessed with an improved charge-pulse fitting algorithm. Two new analysis techniques to reject surface-event backgrounds were applied to the 612 kg days germanium-detector WIMP-search exposure. An extended analysis was also completed by decreasing the 10 keV analysis […]
Kavli Affiliate: Naoyuki Tamura | Summary:We present basic properties of $sim$3,300 emission line galaxies detected by the FastSound survey, which are mostly H$α$ emitters at $z sim$ 1.2-1.5 in the total area of about 20 deg$^2$, with the H$α$ flux sensitivity limit of $sim 1.6 times 10^-16 rm erg cm^-2 s^-1$ at 4.5 sigma. This […]
Kavli Affiliate: Larry Coldren | Summary:In an oxide apertured quantum dot (QD) micropillar cavity-QED system, we found strong QD hysteresis effects and lineshape modifications even at very low intensities corresponding to less than 0.001 intracavity photons. We attribute this to the excitation of charges by the intracavity field; charges that get trapped at the oxide […]
Kavli Affiliate: Larry Coldren | Summary:A polarization degenerate microcavity containing charge-controlled quantum dots (QDs) enables equal coupling of all polarization degrees of freedom of light to the cavity QED system, which we explore through resonant laser spectroscopy. We first measure interference of the two fine-split neutral QD transitions and find very good agreement of this […]
