Contribution

It introduces a numerical analysis of dressed states in a two-component BEC, highlighting their parameter-dependent spatial behavior and manipulation potential.

Findings

Eigenstates are analogous to quantum optics dressed states.

Spatial behavior of dressed states depends on system parameters.

External fields can manipulate the condensate dressed states.

Abstract

A condensate with two internal states coupled by external electromagnetic radiation, is described by coupled Gross Pitaevskii equations, whose eigenstates are analogous to the dressed states of quantum optics. We solve for these eigenstates numerically in the case of one spatial dimension, and explore their properties as a function of system parameters. In contrast to the quantum optical case, the condensate dressed states exhibit spatial behaviour which depends on the system parameters, and can be manipulated by changing the cw external field.
