- Abstract: We propose an extension of Schr\"odinger's equation that incorporates the macroscopic measurement-induced wavefunction collapse phenomenon. Our approach relies on a hybrid between Bohm-de Broglie pilot-wave and objective collapse theories. The Bohmian particle is guided by the wavefunction and, conversely, the wavefunction gradually localizes towards the particle's position. As long as the particle can visit any state, as in a typical microscopic system, the localization effect does not favor any particular quantum state and, on average, the usual Schr\"odinger-like time evolution results. However, when the wavefunction develops spatially well-separated lobes, as would happen during a macroscopic measurement, the Bohmian particle can remain trapped in one lobe, and the wavefunction eventually localizes there. The end result, in macroscopic systems, is a wavefunction collapse that is consistent with Born's rule. We illustrate the theory with a simple double-slit experiment simulation.

It is based on the simultaneous existence of two wave functions in the laboratory reference frame.
The external wave function corresponds to a field that pilots the center-of-mass of the quantum system.
The internal wave function corresponds to the interpretation proposed by Edwin Schr"odinger.

Different attempts to solve the measurement problem of the quantum mechanics (QM) failed because the changes in the quantum formalism lead to contradictions with predictions.
The present work has two purposes: 1) proving that the collapse is unavoidable; 2) applying the CSL model to the process in a detector and showing step by step the modification of the wave-function, until reduction.

We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit.
We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront.
The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
