Quantum critical behavior of ultracold atoms in two-dimensional optical lattices
Xibo Zhang, Chen-Lung Hung, Shih-Kuang Tung +1
As the temperature of a many-body system approaches absolute zero, thermal fluctuations of observables cease and quantum fluctuations dominate. Competition between different energi…

Extracting density-density correlations from in situ images of atomic quantum gases
Chen-Lung Hung, Xibo Zhang, Li-Chung Ha +3
We present a complete recipe to extract the density-density correlations and the static structure factor of a two-dimensional (2D) atomic quantum gas from in situ imaging. Using im…
