“…Such interactions have a variety of applications, such as quadrupole-quadrupole blockade for quantum gates. The experimental testing of the quadrupole blockade and related studies are very similar to the dipole-blockade [23][24][25][26][27][28][29][30][31][32]. These interactions can also be used for quantum information storage at higher densities and quadrupole-quadrupole coupled molecules.…”

The interactions between dipoles are called dipole-dipole interactions. One type of dipole-dipole interaction is van der Waals interaction. Similar to van der Waals interactions, the interactions between quadrupoles are called quadrupole-quadrupole interactions. Atoms can be treated not only as dipoles but also as quadrupoles. In this article, we study the quadrupole interactions between highly excited atoms or Rydberg atoms. In addition, unlike many other calculations, in which the primary focus was on the one-dimensional two-body quadrupole-quadrupole interactions, the primary aim of this article is to study the two-dimensional few-body quadrupole-quadrupole interactions. Specifically, the two-dimensional three-body interactions are investigated. This research has many applications, such as quadrupole-blockade for quantum computing, creating molecules based on quadrupole interactions, or quadrupole-quadrupole molecules.

“…In particular, it has allowed the study of strong-field ionization at intensities beyond saturation [6,10] and provided important insight into XUV-matter interactions [8,11,12]. Recently, ion microscopy has also been applied to the study of Rydberg atoms in strong electric fields [13,14].…”

Ion microscopy is an established technique for laser focus diagnostics and the accurate, intensity-resolved measurement of laser ionization processes. In the present feasibility study, we discuss a new ion microscope design, which improves its resolution across a large range of magnifications and simplifies its operation. Instead of the common two einzel lens configuration, which is usually optimized for a fixed magnification, we propose a generic design consisting of an array of equally spaced ring electrodes, whose individually adjustable voltages are controlled by an evolutionary algorithm. In this way, we can realize aberration minimized magnifications between 25 and 100. Moreover, the algorithm can adjust the voltage settings under changing experimental conditions and facilitates autofocusing for a user-defined magnification.

“…On-resonance quadrupole-quadrupole interactions, which are proportional to 1 R 5 , are experimentally tested [11] in laser-cooled [12][13][14][15][16][17][18] highly excited states [19,20]. Such interactions have a variety of applications, such as quadrupole-quadrupole blockade for quantum gates [21][22][23][24][25][26][27][28][29], quantum information storage at higher densities, and quadrupole-quadrupole coupled molecules. This paper is arranged in the following way: the quadrupole-quadrupole interactions are presented in the next section, which is followed by the discussions about applications to different cases.…”
