A Search for Heterocycles in GOTHAM Observations of TMC-1
Timothy J. Barnum, Mark A. Siebert, Kin Long Kelvin Lee +9
We have conducted an extensive search for nitrogen-, oxygen- and sulfur-bearing heterocycles toward Taurus Molecular Cloud 1 (TMC-1) using the deep, broadband centimeter-wavelength…
Long-range model of vibrational autoionization in core-nonpenetrating Rydberg states of NO
Timothy J. Barnum, Gloria Clausen, Jun Jiang +2
In high orbital angular momentum () Rydberg states, the centrifugal barrier hinders close approach of the Rydberg electron to the ion-core. As a result, these core-non…
Roadmap on STIRAP applications
Klaas Bergmann, Hanns-Christoph Nägerl, Cristian Panda +31
STIRAP (Stimulated Raman Adiabatic Passage) is a powerful laser-based method, usually involving two photons, for efficient and selective transfer of population between quantum stat…
Direct single-shot observation of millimeter wave superradiance in Rydberg-Rydberg transitions
David D. Grimes, Stephen L. Coy, Timothy J. Barnum +3
We have directly detected millimeter wave (mm-wave) free space superradiant emission from Rydberg states () of barium atoms in a single shot. We trigger the cooperative…
Statistical analysis of crystallization database links protein physico-chemical features with crystallization mechanisms
Diana Fusco, Timothy J. Barnum, Andrew E. Bruno +4
X-ray crystallography is the predominant method for obtaining atomic-scale information about biological macromolecules. Despite the success of the technique, obtaining well diffrac…
