Contribution

It introduces a model highlighting the importance of artificial trapping for sustaining quantum degenerate exciton systems in two-dimensional setups.

Findings

Electrostatic traps enable long-lived, uniform exciton fluids.

Experimental systems likely achieved high degeneracy.

Trapping is crucial for quantum degeneracy in excitons.

Abstract

The dynamics of quantum degenerate two-dimensional dipolar excitons confined in electrostatic traps is analyzed and compared to recent experiments. The model results stress the importance of artificial trapping for achieving and sustaining a quantum degenerate exciton fluid in such systems and suggest that a long-lived, spatially uniform, and highly degenerate exciton system was experimentally produced in those electrostatic traps.
