We analyse systematically, from the viewpoint of the nonlinear physics of solitary waves, the effect of the spatial dimension (D = 1,2,3) on the structure and stability of the Bose-Einstein condensates (BECs) trapped in an external anisotropic parabolic potential. While for the positive ...
In fact, many of the properties of superfluid helium also appear in the gaseous Bose–Einstein condensates created by Cornell, Wieman and Ketterle (see below). Superfluid helium-4 is a liquid rather than a gas, which means that the interactions between the atoms are relatively strong; the ...

A new way of controlling the expansion of matter in a freely falling Bose–Einstein condensate (BEC) has produced the coldest effective temperature ever measured: 38 pK (10–12K) above absolute zero. The method, which allowed researchers in Germany and France to image the condensate’s evolution...
We show that both single-component and two-component Bose-Einstein condensates’ (BECs) ground states can be simulated by a deep convolutional neural network. We trained the neural network via inputting the parameters in the dimensionless Gross-Pitaevski
Here we report production of rubidium Bose–Einstein condensates (BECs) in an Earth-orbiting research laboratory, the Cold Atom Lab. We observe subnanokelvin BECs in weak trapping potentials with free-expansion times extending beyond one second, providing an initial demonstration of the advantages ...
We study the ground-state phases of spin–orbit coupled spin-2 Bose–Einstein condensates in a two-dimensional concentrically coupled annular trap with the attractive and repulsive spin-exchange interactions, respectively. For the system with the attractive spin-exchange interaction, the ground-state ph...
We investigate the Josephson oscillation and transition to self-trapping for Bose-Eiristein-Condensates(BECs) in a triple-well trap. 我们使用平均场方法研究了三势阱中玻色-爱因斯坦凝聚体(BECs)的约瑟夫森振荡和自俘获。 5) Bose-Einstein condensate ...
