Development of a Quantum Blackbody Thermometer toward Primary On-orbit Thermometry
Peter J. Beierle, Denis Tremblay, Noah Schlossberger +3
We present a roadmap to a deployable, intrinsically calibrated thermometer with long-term accuracy of 30 mK, exceeding existing on-orbit resistance-based thermometers. Our quantum…
Atomic and molecular systems for radiation thermometry
Stephen P. Eckel, Eric B. Norrgard, Christopher Holloway +3
Atoms and simple molecules are excellent candidates for new standards and sensors because they are both all identical and their properties are determined by the immutable laws of q…
Chirped magneto-optical trap of molybdenum
Sai Naga Manoj Paladugu, Nickolas Pilgram, Stephen Eckel +1
We have directly loaded a cryogenic beam of molybdenum atoms into a magneto-optical trap. By chirping the detuning of the trapping lasers, we were able to enhance the number of ato…
Population-resolved measurement of an avoided crossing of light-dressed states
Noah Schlossberger, Nikunjkumar Prajapati, Eric B. Norrgard +2
A two-level system coupled by a coherent field is a ubiquitous system in atomic and molecular physics. In the rotating wave approximation, the light-dressed states are well describ…
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…
