Disentangling Pauli blocking of atomic decay from cooperative radiation and atomic motion in a 2D Fermi gas
Thomas Bilitewski, Asier Piñeiro Orioli, Christian Sanner +6
The observation of Pauli blocking of atomic spontaneous decay via direct measurements of the atomic population requires the use of long-lived atomic gases where quantum statistics,…
Dipole-dipole frequency shifts in multilevel atoms
A. Cidrim, A. Piñeiro Orioli, C. Sanner +4
Dipole-dipole interactions lead to frequency shifts that are expected to limit the performance of next-generation atomic clocks. In this work, we compute dipolar frequency shifts a…
Thermodynamics of a deeply degenerate SU()-symmetric Fermi gas
Lindsay Sonderhouse, Christian Sanner, Ross B. Hutson +6
Many-body quantum systems can exhibit a striking degree of symmetry unparalleled by their classical counterparts. While in real materials SU() symmetry is an idealization, this…
Emergence of multi-body interactions in few-atom sites of a fermionic lattice clock
A. Goban, R. B. Hutson, G. E. Marti +6
Alkaline-earth (AE) atoms have metastable clock states with minute-long optical lifetimes, high-spin nuclei, and SU()-symmetric interactions that uniquely position them for adva…
