Figure 2From: Double Rashba Quantum Dots Ring as a Spin FilterSpin-dependent conductance G σ and spin polarization p as functions of the Fermi level ɛ with λ = U = 0 and various Δt. In this and all following figures, the normal inter-dot tunneling coupling t c = 1 and the dots ’ levels are ɛ1 = ɛ2 = 0Back to article page
