Quantum quench and non-equilibrium dynamics in lattice-confined spinor condensates
Z. Chen, T. Tang, J. Austin +3
We present an experimental study on non-equilibrium dynamics of a spinor condensate after it is quenched across a superfluid to Mott insulator (MI) phase transition in cubic lattic…
First-order superfluid to Mott-insulator phase transitions in spinor condensates
J. Jiang, L. Zhao, S. -T. Wang +4
We observe evidence of first-order superfluid to Mott-insulator quantum phase transitions in a lattice-confined antiferromagnetic spinor Bose-Einstein condensate. The observed sign…
Antiferromagnetic spinor condensates in a two-dimensional optical lattice
L. Zhao, J. Jiang, T. Tang +2
We experimentally demonstrate that spin dynamics and the phase diagram of spinor condensates can be conveniently tuned by a two-dimensional optical lattice. Spin population oscilla…
Mapping the phase diagram of spinor condensates via adiabatic quantum phase transitions
J. Jiang, L. Zhao, M. Webb +1
We experimentally study two quantum phase transitions in a sodium spinor condensate immersed in a microwave dressing field. We also demonstrate that many previously unexplored regi…
Optimizing a spin-flip Zeeman slower
L. Zhao, J. Jiang, Y. Liu
We present a design of a spin-flip Zeeman slower controlled by a fast feedback circuit for a sodium Bose-Einstein condensate apparatus. We also demonstrate how the efficiency of th…
Dynamics in spinor condensates controlled by a microwave dressing field
L. Zhao, J. Jiang, T. Tang +2
We experimentally study spin dynamics in a sodium antiferromagnetic spinor condensate with off-resonant microwave pulses. In contrast to a magnetic field, a microwave dressing fiel…
A simple and efficient all-optical production of spinor condensates
J. Jiang, L. Zhao, M. Webb +3
We present a simple and optimal experimental scheme for an all-optical production of a sodium spinor Bose-Einstein condensate (BEC). With this scheme, we demonstrate that the numbe…
Optimal transport on supply-demand networks
Yu-Han Chen, Bing-Hong Wang, Li-Chao Zhao +2
Previously, transport networks are usually treated as homogeneous networks, that is, every node has the same function, simultaneously providing and requiring resources. However, so…
