Integer effects in the entanglement and spin fluctuations of a quantum Hall system with Rashba interactions
arXiv:1601.07611 · doi:10.1088/1742-5468/2016/05/053104
Abstract
We report distinct nonanalytic signatures in the spin-orbit entanglement of a 2D electron gas with Rashba interactions at integer values of the filling factor and at certain level crossings. The accompanying sharp changes in the bulk spin-orbit entanglement entropy can be probed by measuring the fluctuation in the transverse spin polarization of the electron gas.
