• Abstract: We analyze the electromagnetic field travelling on resonance with the limiting velocity of the quasi-relativistic particle. We show that a strong longitudinal field leads to the quantum wave function singularity in the form of a shockwave, accompanied by strong energy dissipation. We show that the effect is particularly strong in the case of Dirac electrons in graphene due to the small effective mass. We discuss several experimental tests of these predictions.

  Quantum fluctuations lead to state-dependent non-equilibrium noise, which is exponentially enhanced by wavepacket delocalization. For the case of nanoparticles coupled by the Coulomb interaction such noise can imprint potentially measurable signatures in multiparticle levitation experiments.

  We study the large-scale dynamics of charged particles in a rapidly oscillating field and formulate its classical and quantum effective theory description. Remarkably, the action models the effects of general relativity on the motion of nonrelativistic particles, with the values of the emergent curvature and speed of light determined by the field spatial distribution and frequency.

  We have analyzed the motion of a structured matter wave in the presence of a constant magnetic field and under the influence of a time-dependent external force. From the point of view of the quantum interferometry of matter waves, and also non-relativistic quantum electron microscopy, the results obtained here are important and more reliable than the approximate methods.

  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.
