- W2054255711 abstract "We discuss the quantum dynamics of particles endowed with a position-dependent effective mass within the de Broglie–Bohm causal interpretation of quantum mechanics. The concomitant equations of motion are derived. The main new characteristic exhibited by these equations is that the non-constant mass gives rise to an additional term in the quantum potential and, consequently, to a Hamilton–Jacobi equation different from the one associated with the standard constant mass situation. We analyze, within the Bohmian approach, two particular aspects of the quantum mechanics of particles with non-constant mass that have received special attention in recent literature: (i) the connection rules at abrupt interfaces, and (ii) the form for the kinetic energy operator. We also provide a variational principle based on Fisher's information measure, which generalizes the one recently advanced by Reginatto for particles with constant mass, that leads to the equations of motion for R(r,t) and S(r,t) (Ψ=R1/2 exp(iS/ℏ) being the wave function)." @default.
