Dynamical Casimir effect enhanced by decreasing the mirror reflectivity
Andreson L. C. Rego, Alessandra N. Braga, Jeferson Danilo L. Silva +1
In the present paper, we show that a partially reflecting static mirror with time-dependent properties can produce, via dynamical Casimir effect in the context of a massless scalar…
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…
Casimir effect via a generalized Matsubara formalism
Andreson L. C. Rego, C. A. Linhares, A. P. C. Malbouisson
We investigate the Casimir effect in the context of a nontrivial topology by means of a generalized Matsubara formalism. This is performed in the context of a scalar field in E…
New signatures of the dynamical Casimir effect in a superconducting circuit
Andreson L. C. Rego, Hector O. Silva, Danilo T. Alves +1
We found new signatures of the dynamical Casimir effect (DCE) in the context of superconducting circuits. We show that if the recent experiment made by Wilson {\it et al}, which br…
