反亥姆霍兹线圈和微加工芯片用于磁捕获中性原子，形成玻色-爱因斯坦凝聚体和费米简并气体。尽管它们被广泛使用，但对这些陷阱中涉及的磁场进行详细数值研究的文献并不完整。通过分析和数值研究，研究了反亥姆霍兹线圈和 U 型芯片产生的磁场的物理特性。通过数值模拟强调了电流和这些磁阱的几何方面所发挥的作用。原创研究
Anti-Helmholtz coils and micro-fabricated chips are used for magnetically trapping neutral atoms in forming Bose-Einstein condensates and Fermi degenerate gases. Although they are widely used, literature dealing with a detailed numerical study of the magnetic fi elds involved in these traps is incomplete. Analytical and numerical investigations were carried out to study the physical properties of the magnetic fi elds produced by the anti-Helmholtz coils and a U-chip. The roles played by electric current and geometric aspects of these magnetic traps are emphasized through numerical modelling. original research
