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… Web12 hours ago · The calculations in this paper are summation rather than integration because the probability density function is discrete. The results of 7) and 8) calculated using the parameter α (the ratio of the probability density of 10 USD in the ideal probability density function as a parameter are shown in Fig. 9. From the figure, in Question −1, the ...

WebIn the Schr˜odinger theory, Eq. (1.1b) plays a triple role; besides the probability current ‰u kit determines the charge current e‰u kassociated with a charge density e‰and a kinetic momentum density m‰u kassociated with a mass density m‰. In the Pauli theory the same expressions (1.1a,b) are usually used for probability density and ... WebNov 22, 2013 · In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability (i.e. probability per unit time per unit area). Intuitively, if one pictures the probability density as an inhomogeneous … WebA simple derivation of the spin probability current density from the expectation value of the spin operator is given. The properties of the spin probability current density are then examined in detail. We show that the spin probability current is solenoidal, virtual, and gives null contribution to the momentum of the particle. chillun fantastic beasts
