相对论增强下纠缠和库珀对的行为

Behaviour of entanglement and Cooper pairs under relativistic boosts

Veiko Palge, Vlatko Vedral, Jacob A. Dunningham

摘要:

最近的工作表明,当在相对论框架中提升某些限制几何时,单粒子纠缠态是如何转变的。在这里,我们将这项工作扩展到考虑完全一般的惯性助推。然后,我们将我们的单粒子结果应用到多粒子纠缠,通过关注电子的库珀对。我们表明,一个标准的库珀对状态组成的自旋单重态获得自旋三重态组件在相对论增强惯性框架,无论几何形状。我们还表明,如果我们从一个自旋三重态对开始,三个三重态中的两个获得了一个单重态分量,其大小取决于几何形状。不同的单重态和三重态超导对之间的这种转变可能会让我们更好地理解非常规超导性。

英文摘要:

Recent work has shown how single-particle entangled states are transformed when boosted in relativistic frames for certain restricted geometries. Here we extend that work to consider completely general inertial boosts. We then apply our single particle results to multiparticle entanglements by focussing on Cooper pairs of electrons. We show that a standard Cooper pair state consisting of a spin-singlet acquires spin-triplet components in a relativistically boosted inertial frame, regardless of the geometry. We also show that, if we start with a spin-triplet pair, two out of the three triplet states acquire a singlet component, the size of which depends on the geometry. This transformation between the different singlet and triplet superconducting pairs may lead to a better understanding of unconventional superconductivity.
