Superluminal systematic particle velocity in relativistic stochastic Bohmian mechanics

摘要

For a Dirac electron scattering from a typical metal-insulator-metal tunnel junction (i.e. incident kinetic energy and barrier height both five orders of magnitude less than mc~2) the stationary-state systematic particle velocity of stochastic Bohmian mechanics can be superluminal in the immediate vicinity of a quasinode of the wave function.
