Emergence and Ordering of Polygonal Breathers in Polariton Condensates

TL;DR

This paper demonstrates how dual-frequency pumping induces the formation of polygonal breathers with various symmetries in polariton condensates, revealing spontaneous crystalline and glassy lattice orderings.

Contribution

It introduces a novel mechanism for breather formation via dual-frequency pumping and constructs exotic breathers with discrete rotational symmetries in polariton systems.

Findings

Polygonal breathers with nontrivial symmetries are formed.

Crystalline and glassy lattice orderings emerge spontaneously.

The mechanism is applicable to second-order resonant pumping.

Abstract

We show that the simultaneous driving of a polariton condensate with both nonresonant and n^th order resonant pump frequencies allows for a generic mechanism of breather formation; from this, we construct for the second-order resonance a family of exotic breathers with nontrivial discrete order of rotational symmetry. Finally, we demonstrate the spontaneous emergence of both crystalline and glassy orderings of lattices of polygonal breathers, depending on the degree of polygonal excitations at the lattice sites.
