Local Convertibility and Edge States in Quantum Many Body Systems
Local Convertibility Edge States Quantum Many Body Systems
2016/1/22
In some many-body systems, certain ground-state entanglement (Rényi) entropies increase even as the correlation length decreases. This entanglement nonmonotonicity is a potential indicator of nonclass...
SUB-PIXEL EDGE LOCALIZATION BASED ON LASER WAVEFORM ANALYSIS
Urban Analysis Laser scanning LIDAR Edge Sub-pixel precision
2015/8/13
Laser range data is of high interest in photogrammetry. However, compared to passive imagery, it usually has a lower image
resolution, making geometry extraction and modeling challenging. A method t...
Advances in Edge Sensors for the Thirty Meter Telescope Primary Mirror
Extremely Large Telescopes edge sensors segmented mirrors
2015/5/12
The primary mirror segments are passively constrained in the three lateral degrees of freedom. We evaluate the segment
lateral motions due to the changing gravity vector and temperature, using site ...
The Thirty Meter Telescope project will design and build a thirty-meter diameter telescope for research in astronomy at
optical and infrared wavelengths. The highly segmented primary mirror will use...
Smooth Cascade of Wrinkles at the Edge of a Floating Elastic Film
Thin polymer film liquid uniaxial compression wrinkles wrinkles model capillary force
2014/12/18
An ultrathin polymer sheet floating on a fluid forms a periodic pattern of parallel wrinkles when subjected to uniaxial compression. The wave number of the wrinkle pattern increases sharply near the f...
