Three dimensional cooling and detecting of a nanosphere with a single cavityJul 06 2010Dec 20 2010We propose an experimental scheme to cool and measure the three-dimensional (3D) motion of an optically trapped nanosphere in a cavity. Driven by three lasers on TEM00, TEM01, and TEM10 modes, a single cavity can cool a trapped nanosphere to the quantum ... More
Heating and Dynamics of Two Flare Loop Systems Observed by AIA and EISDec 18 2013We investigate heating and evolution of flare loops in a C4.7 two-ribbon flare on 2011 February 13. From SDO/AIA imaging observations, we can identify two sets of loops. Hinode/EIS spectroscopic observations reveal blueshifts at the feet of both sets ... More
