- Abstract: The extension of Standard Model of the Fundamental Particles which consider
the Lorentz Symmetry Violation governed by a background tensor field presented
by Colladay and Kostelecky consider the hypothesis of having a privileged
direction in the space-time. Here we investigated a extension of the
Schr\"odinger Equation inspired on that model taking into account a background
scalar field. We analyze the behavior of this modified Schr\"odinger equation
on a particle trapped in a well and quantum harmonic oscillator.

We develop a framework of integral quantization applied to the motion of spinless particles in the four-dimensional Minkowski spacetime.
The proposed scheme is based on coherent states generated by the action of the Heisenberg-Weyl group.
A direct application of our model, including a computation of transition amplitudes between states characterized by fixed positions and momenta, is postponed to a forthcoming article.

relativistic quantum dynamics of a scalar particle under the effect of Lorentz symmetry violation determined by a tensor $(K_F)_mu,nu,alpha,beta$ out of the Standard Model Extension is investigated.
We see that the bound-state solution of the modified Klein-Gordon equation can be obtained, and the spectrum of energy and the wave function depends on the Lorentz symmetry breaking parameters.

We study the phenomenon of transmission across the singularity that separates the two half-cylinders.
All the local realisations of the free (Laplace-Beltrami) quantum Hamiltonian are examined as non-equivalent protocols of transmission/reflection.
This allows to comprehend the distinguished status of the so-called bridging' transmission protocol previously identified in the literature.

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.
