Disantangling the effects of Doppler velocity and primordial non-Gaussianity in galaxy power spectra
, 2017 We study the detectability of large-scale velocity effects on galaxy clustering, by simulating galaxy surveys and combining the clustering of different types of tracers of large-scale structure. We employ a set of lognormal mocks that simulate a $20.000$

Coherent Quantum Engineering of Free-Space Laser Cooling [PDF]
, 2006 We perform a quantitative analysis of the cooling dynamics of three-level atomic systems interacting with two distinct lasers. Employing sparse-matrix techniques, we find numerical solutions to the fully quantized master equation in steady state.

Optical and Gamma-Ray Variability Behaviors of 3C 454.3 from 2006 to 2011
, 2018 We present our photometric monitoring of a flat spectrum radio quasar (FSRQ) 3C 454.3 at Yunnan observatories from 2006 to 2011. We find that the optical color of 3C 454.3 shows obvious redder-when-brighter trend, which reaches a saturation stage when ...
