摘要

我们考虑了被困在二维径向周期势中的拉曼诱导自旋张量-动量耦合玻色-爱因斯坦凝聚体的基态性质。通过模拟Gross-Pitaevskii方程，数值研究了自旋张量-动量耦合、失谐和二次塞曼对该系统基态相的影响。结果表明，该系统具有不同的对称性和丰富的基态结构，如环、二瓣和三瓣等，对这些可控参数有很强的依赖性。

Raman-induced Spin-tensor-momentum-coupled Bose-Einstein Condensates in 2D Radially Periodic Potentials

We consider the ground state properties of Raman-induced spin-tensor-momentum-coupled Bose-Einstein condensates trapped in a two-dimensional radially periodic potential. By simulating the Gross-Pitaevskii equations, the effects of spin-tensor-momentum coupling, detuning, and quadratic Zeeman on the ground-state phases of such a system are investigated numerically. Our results show that the system has different symmetry and a rich variety of ground state structures, such as ring, two-lobes and three-lobes, and so on, showing strong dependence on these controllable parameters.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
