Super and Sub-Radiance in a Tunable Spacing Quantum Gas Microscope
POSTER
Abstract
Quantum gas microscopy of radiation coupled many-body systems presents an opportunity to study cooperative effects with single-site resolution and high tunability. With a tunable-spacing quantum gas microscope of erbium atoms we are able to observe and engineer cooperative emission on length scales much larger than the emission light's wavelength. Sweeping the spacing-to-wavelength ratio with an accordion optical lattice reveals geometric resonances in super-radiance that are unique to ordered atomic arrays. Our microscope’s single-site resolution reveals ferromagnetic spatial correlations through super-radiant emission and antiferromagnetic correlations in deeply sub-radiant regimes. To build upon this work we plan to controlably address portions of the Hilbert space by dynamically tuning our accordion lattice and to investigate the interplay of coherent extended Bose-Hubbard dynamics with cooperative emission. In conjunction with this work we present recent developments in investigating the dipolar extended Bose-Hubbard model.
