Reply to Comment on ``Two-dimensional charged-exciton complexes''

TL;DR

This paper defends the validity of a two-body analytical approach to charged-exciton complexes against criticisms, emphasizing differences in modeling methods and questioning the comparison of binding energies.

Contribution

It clarifies the differences between the authors' effective excitonic model and Varga's atomic-like five-body model, reaffirming the original results' validity.

Findings

Original two-body results remain valid within the effective excitonic model.

Criticisms based on atomic system modeling are considered flawed.

Comparison of binding energies across different models is questionable.

Abstract

We respond to criticisms raised by K. Varga (cond-mat/9802262) and reaffirm that the results in our original paper obtained using a two-body analytical method remains valid within the framework of an effective excitonic composite model. The conceptual model of the excitonic systems as well as the numerical method based on variational functions utilized by Varga differ significantly from ours. Hence comparison of binding energies of the charged-biexciton remains questionable. In this reply, we discuss the shortcomings of modelling the charged-biexciton as a five-body system and treating excitonic complexes as atomic systems, as done in Varga's Comment.
