Anthropic constraint on transient variations of fundamental constants
Vsevolod D. Dergachev, Hoang Bao Tran Tan, Sergey A. Varganov +1
The anthropic principle implies that life can emerge and be sustained only in a narrow range of values of fundamental constants. Here we show that anthropic arguments can set power…
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…
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…
