Evidence of quadrupole-quadrupole interactions in ultracold gases [PDF]
, 2022 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.

Development of a high-speed MALDI-triple quadrupole mass spectrometric method for the determination of 3,4-methylenedioxymethamphetamine (MDMA) in oral fluid [PDF]
, 2016 3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) is still a widely used illicit designer drug and its detection in different matrices is of major importance for forensic purposes (e.g.

Electron-scale nested quadrupole Hall field in Cluster observations of magnetic reconnection [PDF]
Annales Geophysicae, 2015 This paper presents the first evidence of a new and unique feature of spontaneous reconnection at multiple sites in electron current sheet, viz. a "nested quadrupole" structure of the Hall field at electron scales, in Cluster observations.

Boundary conditions for quadrupolar metamaterials
New Journal of Physics, 2014 One of the long-standing problems in effective medium theories is using the knowledge of the bulk material response to predict the behavior of the electromagnetic fields at the material boundaries.

Electronic spectroscopy of cold ions in a radio-frequency trap [PDF]
, 2010 The low density of ions in mass spectrometers generally precludes direct absorption measurements. The spectrum of ions can nonetheless be obtained by using resonance two-color photofragmentation or multiphoton photofragmentation techniques.
