Probability current - Wikipedia

In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid. It is a real vector that changes with space and time. Probability currents are analogous to mass currents in hydrodynamics and electric currents in electromagnetism. As in those fields, the probability curre… WebJun 23, 2014 · A spinful electron moving in a potential energy field experiences the spin-orbit interaction, and that additional term in the time-dependent Schrödinger equation places … Web0 0.5 1 1.5 2 2.5 3 ω / ω p 0 0.5 1 1.5 2 n(ω) n r n i bold = real part light = imag part For γ = 0.02 ω p Free electron gas, index of refraction Figure 1: Plot of the real and imaginary parts of the index of refraction n(ω) = itools localisation
