Evidence of quadrupole-quadrupole interactions in ultracold gases
Jianing Han, Juliet Michell, Morgan Umstead
Van der Waals interactions are interactions between dipoles. Similarly, quadrupole-quadrupole interactions are interactions between quadrupoles. In this article, we focus on the in…
Two-dimensional three-body quadrupole-quadrupole interactions
Jianing Han
Similar to interactions between dipoles, or van der Waals interactions, quadrupole-quadrupole interactions are interactions between quadrupoles. In this article, we study the quadr…
Electric field excitation suppression in cold atoms
Jianing Han, Juliet Mitchell, Morgan Umstead
In this article, the atom excitation suppression is studied in two ways. The first way of exploring the excitation suppression is by an external DC electric field. The second way i…
A magneto-optical trap created by the 2nd-order external cavity diode lasers
Jianing Han, Lindsay Hutcherson, Gayatri Deshmukh +5
In this article, we report on a magneto-optical trap (MOT) created by the 2nd-order external cavity diode lasers (ECDLs). The lasers were characterized. We have observed the non-co…
