Studies of disorder in fastionics and of a nuclear quadrupole interaction in ordered markets [PDF]
, 1980 This thesis consists of two completely separate parts. In Part I, we look at disorder in fastionic conductors, and in Part II we examine the pseudoquadrupole effect in ordered magnets.

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.
