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…
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…
Efficient algebraic solution for a time-dependent quantum harmonic oscillator
D. M. Tibaduiza, L. B. Pires, D. Szilard +3
Using operator ordering techniques based on BCH-like relations of the su(1,1) Lie algebra and a time-splitting approach,we present an alternative method of solving the dynamics of…
Inhibition of the dynamical Casimir effect with Robin boundary conditions
Andreson L. C. Rego, B. W. Mintz, C. Farina +1
We consider a real massless scalar field in 3+1 dimensions satisfying a Robin boundary condition at a nonrelativistic moving mirror. Considering vacuum as the initial field state,…
Time evolution of the energy density inside a non-static cavity with a thermal, coherent and a Schrodinger cat state
Danilo T. Alves, Edney R. Granhen, Mateus G. Lima +2
In this paper we investigate the time evolution of the energy density for a real massless scalar field in a two-dimensional spacetime, inside a non-static cavity, taking as basis t…
