论文摘要
范德华的相互作用是偶极子之间的相互作用。同样，四极素二极管的相互作用是四极杆之间的相互作用。在本文中，我们专注于两个偶极或两个四枢轴之间的相互作用。从经典上讲，我们将一个Rydberg原子视为偶极子。外部激发电子和离子芯是偶极子的两个极。量子在机械上，我们考虑Rydberg过渡偶极子。因此，偶极 - 偶极相互作用是两个Rydberg原子之间的相互作用。 rydberg原子具有四极杆成分；因此，两个rydberg原子之间的相互作用具有四极核的相互作用成分。在本文中，我们研究了偶极 - 偶极子和四极菌素对Ultracold Rydberg原子之间相互作用的贡献。结果表明，已经观察到了四极杆块的证据，这对于制造更紧凑的量子计算机，量子电子设备以及量子传感至关重要。
Van der Waals interactions are interactions between dipoles. Similarly, quadrupole-quadrupole interactions are interactions between quadrupoles. In this article, we focus on the interactions between two dipoles or two quadrupoles. Classically, we treat one Rydberg atom as a dipole; an outer excited electron and an ion core are the two poles of a dipole. Quantum mechanically, we consider Rydberg transition dipoles. Therefore, dipole-dipole interactions are the interactions between two Rydberg atoms. Rydberg atoms have quadrupole components; consequently, the interactions between two Rydberg atoms have quadrupole-quadrupole interaction components. In this article, we examine the dipole-dipole and quadrupole-quadrupole contribution to the interactions between ultracold Rydberg atoms. It is shown that the evidence of quadrupole-blockade has been observed, which is essential for fabricating more compact quantum computers, quantum electronics, as well as quantum sensing.
