Ultralong spin coherence times for rubidium atoms in solid parahydrogen via dynamical decoupling
Sunil Upadhyay, Ugne Dargyte, David Patterson +1
Coherence time is an essential parameter for quantum sensing, quantum information, and quantum computation. In this work, we demonstrate electron spin coherence times as long as 0.…
Spin coherence and optical properties of alkali-metal atoms in solid parahydrogen
Sunil Upadhyay, Ugne Dargyte, Vsevolod D. Dergachev +5
We present a joint experimental and theoretical study of spin coherence properties of 39K, 85Rb, 87Rb, and 133Cs atoms trapped in a solid parahydrogen matrix. We use optical pumpin…
High Sensitivity Microwave Spectroscopy in a Cryogenic Buffer Gas Cell
Jessica P. Porterfield, Lincoln Satterthwaite, Sandra Eibenberger +2
We describe an instrument which can be used to analyze complex chemical mixtures at high resolution and high sensitivity. Molecules are collisionally cooled with helium gas at cryo…
Automated, context-free assignment of asymmetric rotor microwave spectra
Lia Yeh, Lincoln Satterthwaite, David Patterson
We present a new algorithm, Robust Automated Assignment of Rigid Rotors (RAARR), for assigning rotational spectra of asymmetric tops. The RAARR algorithm can automatically assign e…
Enhanced spin coherence of rubidium atoms in solid parahydrogen
Sunil Upadhyay, Ugne Dargyte, Robert P. Prater +5
We measure the transverse relaxation of the spin state of an ensemble of ground-state rubidium atoms trapped in solid parahydrogen at cryogenic temperatures. We find the spin depha…
A study of the ozonolysis of isoprene in a cryogenic buffer gas cell by high resolution microwave spectroscopy
Jessica P. Porterfield, Sandra Eibenberger, Dave Patterson +1
We have developed a method to quantify reaction product ratios using high resolution microwave spectroscopy in a cryogenic buffer gas cell. We demonstrate the power of this method…
