Probability and complex quantum trajectories

Abstract: It is shown that in the complex trajectory representation of quantum mechanics, the Born's Ψ ⋆ Ψ probability density can be obtained from the imaginary part of the velocity field of particles on the real axis. Extending this probability axiom to the complex plane, we first attempt to find a probability density by solving an appropriate conservation equation. The characteristic curves of this conservation equation are found to be the same as the complex paths of particles in the new representation. The boundary… Show more

“…As in the previous case, the MdBB equations of motion is given by (16), but with (x, y, z) as complex variables. The partial derivatives to be used in these equations are, respectively, given by equations (12), (13) and (14).…”

“…It may be noted that dBB is not the only quantum trajectory formalism available in the literature. The Floyd, Faraggi and Matone (FFM) [10] and the modified de Broglie-Bohn (MdBB) [11,12,13,14,15] trajectory representations have also received wide attention in recent years. The equations of motion used in dBB and MdBB schemes are alike, of the general form mṙ i = ∇ i S, where S represents the Hamilton-Jacobi functions in the respective quantum Hamilton-Jacobi equations in the two schemes.…”

“…A clear advantage of the MdBB complex representation over other trajectory formalisms is that in it the Born probability distribution along the real line can be directly obtained from the velocity field [23]. It is seen that an exponential function involving the integral of the imaginary part of the MdBB velocity field provides this distribution in such a way that on the real line, the more we are inside the closed trajectories, the larger is the probability density.…”

“…This author proposed a timedependent complex quantum trajectory formalism (based on the same connection formula mentioned by Leacock and Padgett) to study the dynamics associated with some simple analytical cases, such as the harmonic oscillator or the step barrier. Later on this modified de BroglieBohm approach, as denoted by John, has also been applied to the analysis of the Born rule and the normalization conditions of the probability density in the complex plane [374,375], or the dynamics of coherent states [376,377]. Analogous studies carried out to determine different dynamical properties with this complex Bohmian representation have been carried out extensively in the literature [349,[378][379][380][381][382][383][384][385][386][387][388][389][390][391][392][393][394][395][396][397].…”
