Many-Body Super- and Subradiance in Ordered Atomic Arrays

Description

Study of collective light-matter interactions in geometrically ordered, spatially extended atom arrays with subwavelength spacing.

Physical System

Ordered Atomic Arrays

• 2D atom arrays with subwavelength spacing
• Site-resolved imaging capability
• Programmable geometry

Collective Regime

• Beyond point-like or homogeneous ensembles
• Network of photon-mediated interactions
• Not confined to single Dicke mode

Key Phenomena

Superradiance

• Nature: Ferromagnetic
• Characteristics: Intense collective emission
• Scaling: Extensive scaling observed
• Features: Superradiant revivals

Subradiance

• Nature: Antiferromagnetic
• Characteristics: Strongly suppressed decay
• Applications: Long-lived photon storage
• Properties: Dark modes for quantum information

Spatial Correlations

• Build-up directly observed
• Transformation of cooperative decay
• Strongly correlated many-body process

Experimental Capabilities

Subwavelength Arrays

• Geometrically ordered structures
• Spatially extended (not point-like)
• Subwavelength spacing between atoms

Imaging and Control

• Site-resolved imaging despite subwavelength spacing
• Programmable configurations
