Résumé

Far-infrared radiation absorption of a quantum dot with few electrons in an orthogonal magnetic field could monitor the crossover to the fully spin-polarized state. A Rashba spin-orbit coupling can tune the energy and the spin density of the first excited state that has a spin texture carrying one extra unit of angular momentum. The spin-orbit coupling can squeeze a flipped spin density at the center of the dot and can increase the gap in the spectrum.
