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…
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…
Time-dependent Robin boundary conditions in the dynamical Casimir effect
C. Farina, Hector O. Silva, Andreson L. C. Rego +1
Motivated by experiments in which moving boundaries are simulated by time-dependent properties of static systems, we discuss the model of a massless scalar field submitted to a tim…
Dynamical Casimir effect for a massless scalar field between two concentric spherical shells with mixed boundary condictions
F. Pascoal, L. C. Céleri, S. S. Mizrahi +2
We analyze the dynamical Casimir effect for a massless scalar field confined between two concentric spherical shells which impose on the field mixed boundary conditions. We thus co…
Primitively divergent diagrams in -deformed scalar field with quartic self-interaction
M. J. Neves, C. A. A. de Carvalho, C. Farina +1
We obtain the primitively divergent diagrams in -deformed scalar field in four-dimensional spacetime with quartic self-interaction in order to investigate the effect of the fund…
Quantum radiation pressure on a moving mirror at finite temperature
L. A. S. Machado, P. A. Maia Neto, C. Farina
We compute the radiation pressure force on a moving mirror, in the nonrelativistic approximation, assuming the field to be at temperature At high temperature, the force has a…
Generalized partition functions, interpolating statistics and higher virial coefficients
P. F. Borges, H. Boschi-Filho, C. Farina
Starting from determinants at finite temperature obeying an intermediate boundary condition between the periodic (bosonic) and antiperiodic (fermionic) cases, we find results which…
Magnetic Permeability of Constrained Fermionic Vacuum
M. V. Cougo-Pinto, C. Farina, A. Tort +1
We obtain using Schwinger's proper time approach the Casimir-Euler-Heisenberg effective action of fermion fluctuations for the case of an applied magnetic field. We implement here…
The Partition Function for an Anyon-Like Oscillator
H. Boschi-Filho, C. Farina, A. de Souza Dutra
We compute the partition function of an anyon-like harmonic oscillator. The well known results for both the bosonic and fermionic oscillators are then reobtained as particular case…
