Intrinsic bistability and dual-core dark solitons and vortices in exciton polariton condensates

TL;DR

This paper introduces a novel class of dual-core dark solitons and vortices in exciton-polariton condensates, characterized by intrinsic bistability and distinct localization scales, expanding understanding of nonlinear excitations in these systems.

Contribution

It reveals the existence of dual-core dark solitons and vortices arising from intrinsic multiplicity of exciton density solutions, a new phenomenon in exciton-polariton condensates.

Findings

Identification of dual-core dark solitons and vortices

Characterization of solutions with two distinct localization scales

Link between solution multiplicity and excitonic discontinuity

Abstract

We investigate a new kind of dark solitons and vortices that can exist in the exciton-polariton condensates. These structures have discontinuity in the excitonic part of the polaritonic field and exist due to an intrinsic multiplicity of the solutions for the exciton density in the given optical field. Reported solutions are characterized by two very distinct localization scales, and hence are coined as dual-core dark solitons and vortices.
