We develop a matrix perturbation method for the Lindblad master equation. The first‐and
second‐order corrections are obtained and the method is generalized for higher orders. The …

The inverse of the Vandermonde and confluent Vandermonde matrices are presented. In the
case of the Vandermonde matrix, we present a decomposition in three factors, one of them a …

In this paper we will argue that the superposition of waves can be calculated in a simple
way. We show, using the Gauss's method to sum an arithmetic sequence, how it is possible …

This chapter presents the Matrix Perturbation Method for the Lindblad master equation,
which provides both first-and second-order corrections; to ensure generality, the method is …

We solve exactly the master equation of the degenerate and nondegenerate parametric
oscillator in the presence of a squeezed reservoir. We show that the formal solutions of both …

Los sistemas físicos abiertos, esdecir, aquellos que interaccionan con el medio ambiente,
constituyen un problema actual de mucha importancia. Las continuas fluctuaciones y los …

We study the field entropy squeezing as a measure of the entanglement in a three-level
system interacting with a cavity field. Numerical calculations under current experimental …
