• Abstract: Prompted by the longstanding interpretational controversy in quantum mechanics, quantum tunneling is heuristically addressed within the Everettian quantum multiverse. In this framework, the universal wavefunction splits into decohered reflected and transmitted branches under the environmetal effect after encountring a potential barrier. The observed tunneling is then experienced by the observer located in a tunneled world. The tunneling probability and the tunneling time are investigated in terms of the tunneled world relative weights and the branching duration, respectively. The macroscopic quantum tunneling, recently honored, is also discussed and the corresponding macroscopic tunneling time is approached based on the obtained results and known data.

  We prove by linking the QFT property of micro-causality to the wavepacket behavior that the tunneling dynamics is fully causal. In all cases (Klein tunneling or regular tunneling across a standard or a supercritical potential) the transmitted wavepacket remains in the causal envelope of the propagator.

  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.
