Motion induced by asymmetric excitation of the quantum vacuum
Jeferson Danilo L. Silva, Alessandra N. Braga, Andreson L. C. Rego +1
During the last fifty-one years, the effect of excitation of the quantum vacuum field induced by its coupling with a moving object has been systematically studied. Here, we propose…
Solving two-dimensional non-relativistic electronic and muonic atoms governed by Chern-Simon potential
Francisco Caruso, José A. Helayël-Neto, Vitor Oguri +1
Bidimensional muonic and electronic atoms, with nuclei composed of a proton, deuteron, and triton, and governed by Chern-Simons potential, are numerically solved. Their eigenvalues…
Still learning about space dimensionality: from the description of hydrogen atom by a generalized wave equation for dimensions D3
Francisco Caruso, Vitor Oguri, Felipe Silveira
The hydrogen atom is supposed to be described by a generalization of Schrödinger equation, in which the Hamiltonian depends on an iterated Laplacian and a Coulomb-like potential $r…
Quantum relaxation in a system of harmonic oscillators with time-dependent coupling
F. B. Lustosa, S. Colin, S. E. Perez Bergliaffa
In the context of the de Broglie-Bohm pilot wave theory, numerical simulations for simple systems have shown that states that are initially out of quantum equilibrium - thus violat…
A time-dependent harmonic oscillator with two frequency jumps: an exact algebraic solution
D. M. Tibaduiza, L. Pires, A. L. C. Rego +3
We consider a harmonic oscillator (HO) with a time dependent frequency which undergoes two successive abrupt changes. By assumption, the HO starts in its fundamental state with fre…
