Entanglement control in coupled two-mode boson systems

TL;DR

This paper investigates how entanglement evolves over time in a two-mode boson system, revealing that interaction strengths and initial states influence entanglement and squeezing independently, with implications for quantum control.

Contribution

It provides an analytical expression for entanglement dynamics in a two-mode boson model, highlighting independent control of entanglement and squeezing based on system parameters.

Findings

Entanglement dynamics depend on interaction strengths and initial states.

Entanglement and squeezing can evolve independently in the system.

Analytical expression derived for time-dependent entanglement.

Abstract

A two-mode boson model, widely used for the physics of fast rotating nuclei and Bose-Einstein condensates, is studied in the context of entanglement control. We derive an analytical expression for the entanglement between the fields in this model as a function of time. We found that depending on the interaction strengths between boson modes and the nature of the initial boson states the dynamical evolution of the entanglement and the squeezing can occur independently.
