Compact Blackbody Radiation Atomic Sensor: Measuring Temperature using Optically Excited Atoms in Vapor Cells
David S. La Mantia, Mingxin Lei, Nikunjkumar Prajapati +6
We demonstrate a blackbody radiation thermometer based on optically excited rubidium atoms in a vapor cell. The temperature measurement is fast, with statistical uncertainty as low…
Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms
Noah Schlossberger, Andrew P. Rotunno, Stephen P. Eckel +14
Rydberg states of alkali atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently…
Revisiting collisional broadening of Rb Rydberg levels: conclusions for vapor cell manufacture
Mingxin Lei, Stephen P. Eckel, Eric B. Norrgard +4
Electrometry based on electromagnetically induced transparency (EIT) in alkali Rydberg vapor cells may suffer reduced sensitivity due to spurious line broadening effects, caused by…
Observation of Asymmetric Sideband Generation in Strongly-driven Rydberg Atoms
Dangka Shylla, Nikunjkumar Prajapati, Andrew P. Rotunno +7
Improving the bandwidth of Rydberg atom-based receivers is an ongoing challenge owing to the long-lived Rydberg state lifetimes that limit the refresh rate of ground state atoms. I…
