- Abstract: The correlation between particle and wave descriptions of electron-matter
interactions is analyzed by measuring the delocalization of an evanescent field
using electron microscopy. Its spatial extension coincides with the
energy-dependent, self-coherence length of propagating wave packets that obey
the time-dependent Schr\"odinger equation and undergo a Goos-H\"anchen shift.
In the Heisenberg limit they are created by self-interferences during
coherent-inelastic Coulomb interactions with a decoherence phase {\Delta}{\phi}
= 0.5 rad and shrink to particle-like dimensions for energy losses of more than
1000 eV.

Peierls transition, a hot topic in condensed matter physics, is usually believed to occur in the one-dimensional fermionic systems.
We show that, by means of perturbation analysis and numerical density-matrix renormalization group method, a bosonic analog of the Peierls state can occur in proper parameters regimes.

macroscopic correlations involving macroscopic distances can be observed between entangled photons as well as in atomic gases and matter waves at low temperatures.
We reveal a manifestation of quantum mechanics that involves macroscopic distances and results in a nearly complete depletion of coherence.
Our results suggest an approach to measuring the vacuum temperature and nondestructively sensing the presence of distant objects.

We present a new interpretation of quantum mechanics, called the double-scale theory.
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.

We study the effects of strong inter-particle interaction on diffraction of a Bose-Einstein condensate of $6Li$ molecules created by pulses of a standing wave.
For short pulses we observe the standard Kapitza-Dirac diffraction, with the contrast of the diffraction pattern strongly reduced for very large interactions.
For longer pulses diffraction shows the characteristic for matter waves impinging on an array of tubes and coherent channeling transport.

We argue that spectroscopic experiments offer a technologically feasible platform to explore the effects of quantum time dilation.

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.
