Chiral solitons in spinor polariton rings

TL;DR

This paper theoretically investigates chiral solitons in spinor polariton rings, revealing how geometric phases from magnetic fields and TE-TM splitting induce non-equivalent clockwise and anticlockwise soliton propagation, akin to an Aharonov-Bohm effect.

Contribution

It introduces a new class of rotating localized defect solutions in polariton rings considering realistic parameters, highlighting the role of geometric phases in soliton chirality.

Findings

Chiral solitons exhibit non-equivalent propagation directions due to geometric phase effects.

The interplay of magnetic field and TE-TM splitting induces chirality in polariton solitons.

The system demonstrates an analog of the Aharonov-Bohm effect for solitons.

Abstract

We consider theoretically one-dimensional polariton ring accounting for both longitudinal-transverse (TE-TM) and Zeeman splitting of spinor polariton states and spin dependent polariton-polariton interactions. We present the novel class of solutions in the form of the localized defects rotating with constant angular velocity and analyze their properties for realistic values of the parameters of the system. We show that the effects of the geometric phase arising from the interplay between external magnetic field and TE-TM splitting introduce chirality in the system and make solitons propagating in clockwise and anticlockwise directions non equivalent. This can be interpreted as solitonic analog of Aharonov-Bohm effect.
