TL;DR

This paper demonstrates how to dynamically create magnetic states in a strongly interacting two-component Bose gas by mapping it to a spin chain model, showing transitions between ferromagnetic and antiferromagnetic configurations.

Contribution

It introduces a method to realize magnetic states dynamically in a Bose mixture using an effective spin chain mapping, highlighting the transition between magnetic phases.

Findings

Spatial profiles transition from ferromagnetic to antiferromagnetic states.

Dynamical spin densities and fidelities are computed for few-body systems.

Effective spin chain model accurately describes the system's magnetic behavior.

Abstract

We describe the dynamical preparation of magnetic states in a strongly interacting two-component Bose gas in a harmonic trap. By mapping this system to an effective spin chain model, we obtain the dynamical spin densities and the fidelities for a few-body system. We show that the spatial profiles transit between ferromagnetic and antiferromagnetic states as the intraspecies interaction parameter is slowly increased.
