Information-theoretic measures of electron correlation in a double quantum dot
W. S. Nascimento, A. M. Maniero, F. V. Prudente +1
In this work, we investigated how variations in spatial confinement affect the electron correlation between two electrons in a symmetric double quantum dot. In strong confinement r…
Entropy production and statistical relaxation of dipolar bosons and fermions in interaction quench dynamics
Barnali Chakrabarti, N D Chavda, F. V. Prudente
We study the out-of-equilibrium dynamics of dipolar bosons and fermions after a sudden change in the interaction strength from zero to a finite repulsive value. We simulate the int…
Informational analysis of the confinement of an electron in an asymmetric double quantum dot
W. S. Nascimento, A. M. Maniero, F. V. Prudente +2
A quasi-unidimensional one-electron double quantum dot is studied within the framework of Shannon informational entropy. Its confinement potential, which is described by an asymmet…
Electron Confinement study in a double quantum dot by means of Shannon Entropy Information
Wallas S. Nascimento, Angelo M. Maniero, Frederico V. Prudente +2
In this work, we use the Shannon informational entropies to study an electron confined in a double quantum dot; we mean the entropy in the space of positions, , in the space o…
3D two-electron double quantum dot: comparison between the behavior of some physical quantities under two different confinement potentials in the presence of a magnetic field
A. M. Maniero, F. V. Prudente, C. R. de Carvalho +1
We have considered a system consisting of two coupled quantum dots containing two electrons, i.e., two quantum dots next to each other with one excess electron each, subjected to a…
On the oscillating properties of a two-electron quantum dot in the presence of a magnetic field
Angelo M. Maniero, Carlos R. de Carvalho, Frederico V. Prudente +1
We give a basic explanation for the oscillating properties of some physical quantities of a two-electron quantum dot in the presence of a static magnetic field. This behaviour was…
Coulomb Correlation and Information Entropies in Confined Helium-Like Atoms
Wallas S. Nascimento, Marcos M. de Almeida, Frederico V. Prudente
The present work studies aspects of the electronic correlation in confined H, He and Li atoms in their ground states using the informational entropies. In this way, diffe…
Evaluating Bohm's quantum force in the scattering process by a classical potential
Wanisson S. Santana, Clebson Cruz, Elisama Lima +1
In this work, we show an application of the de Broglie-Bohm Quantum Theory of Motion (QTM) as a powerful tool for evaluating Bohm's quantum force in the scattering process of a Gau…
Information and quantum theories: an analysis in one-dimensional systems
Wallas S. Nascimento, Marcos M. de Almeida, Frederico V. Prudente
We pedagogically present the information theory as originally established, explaining its essential ideas and paying attention to the expression employed to measure the amount of i…
Effect of a laser field in the confinement potential of two electrons in a double quantum dot
A. M. Maniero, C. R. de Carvalho, F. V. Prudente +1
We have studied a system consisted of two coupled quantum dots containing two electrons subjected by a laser field. The effect of the laser is described by the dressed-band approac…
Shannon entropy: a study of confined hydrogenic-like atoms
Wallas S. Nascimento, Frederico V. Prudente
The Shannon entropy in the atomic, molecular and chemical physics context is presented by using as test cases the hydrogenic-like atoms , and confined…
Determination of the scattering length for Rb-Cs X ground electronic state using a variational method
M. N. Guimarães, F. V. Prudente
We performed the calculation of the scattering length for the elastic collision between the rubidium and cesium atoms. For this we applied a variational procedure based on the R-ma…
