Simultaneous control of populations and coherence phase of open two-level quantum systems with a single pulse
Gustavo Fernandes da Costa, Emanuel Fernandes de Lima
We address the control of the dynamics of both population and coherence phase in an open two-level quantum system employing a single external control field. The system dynamics is…

Control of the classical dynamics of a particle in the Morse-soft-Coulomb potential
Gabriel Albertin Amici, José Andrés Guzmán Morán, Emanuel Fernandes de Lima
We introduce the one-dimensional Morse-soft-Coulomb (MsC) potential consisting of a Morse repulsive barrier smoothly connected with a soft-core Coulomb potential at the origin. Thi…

Reverse engineering control of relative phase and populations of two-level quantum systems
Felipe Silveira Fagundes, Emanuel Fernandes de Lima
We consider the simultaneous control of the relative phase and populations of two-level quantum systems by an external field. We apply a reverse engineering approach, which allows…
