Statistical anisotropy of CMB as a probe of conformal rolling scenario
Statistical anisotropy CMB probe conformal rolling scenario
2012/2/21
Search for the statistical anisotropy in the CMB data is a powerful tool for constraining models of the early Universe. In this paper we focus on the recently proposed cosmological scenario with confo...
We present a novel fiber-based near-field optical head consisting of a straw-shaped writing probe and a flat gap sensing probe. The strawshaped probe with a C-aperture on the end face exhibits enhance...
Hypervelocity Impact of the Icy Droplet on Al Shell at Nanoscale: A Molecular Dynamics Probe
hypervelocity impact molecular dynamics debris cloud icy droplet
2012/9/24
Large-scale molecular dynamics (MD) simulations are conducted to investigate the hypervelocity impact of the icy droplet on spacecraft Al shell at the atom ic level. The velocity of the droplet is se...
Probe combination in large galaxy surveys : Application of Fisher information and Shannon entropy to weak lensing
cosmology: cosmological parameters cosmology: large-scale structure of the Universe methods: data analysis methods: statistical
2011/9/27
This paper is aimed at developing a better understanding of the structure of the information that in contained in galaxy surveys, so as to find optimal ways to combine observables from such surveys. W...
Transient photoluminescence enhancement as a probe of the structure of impurity-trapped excitons in CaF$_2$:Yb$^{2+}$
photoluminescence enhancement impurity-trapped excitons Materials Science
2011/8/17
Abstract: We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF$_2$:Yb$^{2+}$. The radically different radiative decay rates of the lowest exciton state and high...
Effect of a plasma grating on pump-probe experiments near the ionization threshold in gases
plasma pump-probe experiments ionization threshold gases
2011/8/4
Abstract: Calculations are performed of the phase shift caused by the spatial modulation in the plasma density due to interference between a strong pump pulse and a weak probe pulse. It is suggested t...

On A Cosmological Invariant as an Observational Probe in the Early Universe
Cosmological Invariant Observational Probe
2011/1/11
k-essence scalar field models are usually taken to have lagrangians of the form ${\mathcal L}=-V(\phi)F(X)$ with $F$ some general function of $X=\nabla_{\mu}\phi\nabla^{\mu}\phi$. Under certain condit...
Three Roads to Probe-Brane Superconductivity
Probe-Brane Superconductivity High Energy Physics
2010/12/24
We study a defect system of two parallel D5 probe branes in a large-N_c D3 background. Using the non-abelian DBI action, we study three different fields that can give rise to a superconducting phase t...
