Topological Bose-Mott Insulators One-Dimensional Optical Superlattice
2016/1/23
Ultracold atoms in optical lattices can be used to simulate strongly correlated many-body models that are central to the understanding of condensed matter physics. This simulation has attracted a lot ...
Proposal for observing non-Abelian statistics of Majorana-Shockley fermions in an optical lattice
non-Abelian statistics Majorana-Shockley fermions an optical lattice
2016/1/22
Besides the conventional bosons and fermions, in synthetic two-dimensional (2D) materials there could exist more exotic quasiparticles with non-Abelian statistics, meaning that the quantum states in t...
comparison of dem generation and combination methods using high resolution optical stereo imagery and interferometric sar data
DEM/DTM High resolution Combination Fusion Accuracy Multisensor Optical SAR
2015/9/1
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, IKONOS) and...
