• Abstract: In this work, we enhance the Bohr model of the hydrogen atom by incorporating Stochastic Mechanics to describe the electron's behavior through Brownian motion. In contrast to traditional quantum mechanics, where the Born rule postulates the physical interpretation of the wave function, our model derives the Born rule by performing statistical averaging of single-particle positions. Because the particle always has a definite, though random, position, there is no need for wave function collapse, as required by the Copenhagen interpretation. In this approach, we use the wave function to compute the electron's optimal drift velocity within its stochastic equation of motion. We develop modified stochastic equations in curvilinear spherical coordinates and demonstrate that the resulting radial and angular kinetic energies align with those from the operator approach. Numerical simulations validate our theoretical framework by showing stable electron orbits and accurately reproducing the probability distribution of finding the electron around the hydrogen nucleus as defined by the Born rule. We show that at very short timescales, wave function-based single electron probability distributions can be inadequate due to insufficient statistical averaging of single-particle trajectories. This model thus offers enhanced insights into the quantum world beyond conventional interpretations. Our findings underscore the potential of applying wave function-derived drift velocities within Stochastic Mechanics to the hydrogen atom, providing new perspectives on atomic dynamics.

  This study demonstrates the existence of an evanescent electron wave outside both finite and infinite quantum wells. We show that this evanescent wave shares the spin characteristics of the wave confined within the well. Our findings suggest that the electron cannot be confined to a mathematical singularity and that quantum information, or quantum entropy, can leak through any confinement.

  We propose an interpretative framework for quantum mechanics corresponding to the specifications of Louis de Broglie's double-solution theory. The principle is to decompose the evolution of a quantum system into two wave functions. For Schr"odinger, the particles are extended and the square of the module of the (internal) wave function of an electron corresponds to the density of its charge in space.
