Quantum Statistical Properties of a Nanoelectromechanical System

In the present work, we devised an interaction model between a quantum nanoelectromechanical system (QNEMS) and a quantum bit (QBit), such that the effective Hamiltonian of the model results in a parametric oscillator. The implication is that the statistical properties of the QNEMS modes are dynamic...

Description
Summary:In the present work, we devised an interaction model between a quantum nanoelectromechanical system (QNEMS) and a quantum bit (QBit), such that the effective Hamiltonian of the model results in a parametric oscillator. The implication is that the statistical properties of the QNEMS modes are dynamical, leading to bunching and antibunching of phonons. We also present two situations in which we obtain sub- and super-poissonian distributions.
