Exploring quantum criticality based on ultracold atoms in optical lattices
Xibo Zhang, Chen-Lung Hung, Shih-Kuang Tung +2
Critical behavior developed near a quantum phase transition, interesting in its own right, offers exciting opportunities to explore the universality of strongly-correlated systems…
Observation of scale invariance and universality in two-dimensional Bose gases
Chen-Lung Hung, Xibo Zhang, Nathan Gemelke +1
The collective behavior of a many-body system near a continuous phase transition is insensitive to the details of its microscopic physics[1]. Characteristic features near the phase…
Slow Mass Transport and Statistical Evolution of An Atomic Gas Across the Superfluid-Mott Insulator Transition
Chen-Lung Hung, Xibo Zhang, Nathan Gemelke +1
We study transport dynamics of ultracold cesium atoms in a two-dimensional optical lattice across the superfluid-Mott insulator transition based on in situ imaging. Inducing the ph…
