在与精神分析的类比中，可以说今天的技术利用了电子的双重人格，一个是负的（它的电荷），一个是反社会的（它的自旋为1/2），而这两者通常是分开考虑的。第一种方法使通过电场产生电荷流和逻辑器件变得容易。后者负责铁磁性（连同库仑相互作用），它主导着信息存储技术。这两种特性之间的联系是自旋-轨道耦合，由于其相对论性，这在固体中是一种弱相互作用。虽然弱，但自旋轨道耦合可以对材料特性产生深远的影响，并且是几种潜在技术上有用的效应的来源。
In an analogy with psychoanalysis, it can be said that today’s technology exploits the dual personalities of the electron, one negative (its charge) and one antisocial (its spin 1/2), and that these are usually considered separately. The first makes it easy to generate charge flow and logic devices via electric fields. The latter is responsible for ferromagnetism (together with the Coulomb interaction), which dominates information storage technologies. The link between these two personalities is the spin-orbit coupling, which is a weak interaction in solids because of its relativistic nature. Though weak, the spinorbit coupling can have profound consequences for materials properties and is the source of several, potentially technologically useful, effects.
