Feasibility of extracting the proton weak charge from quantum-control measurements of atomic parity violation on the or transition in hydrogen
Jiguang Li, Andrei Derevianko, D. S. Elliott
We explore the feasibility of extracting electroweak observables from a measurement of atomic parity violation in hydrogen. Our proposed quantum-control scheme focuses on the $2s-3…
Nuclear-spin-dependent corrections to the transition polarizability in cesium
D. Xiao, H. B. Tran Tan, A. Derevianko
The Stark-interference technique is commonly used to amplify the feeble parity-violating signal in atomic experiments. As a result, interpretation of these experiments in terms of…
Reevaluation of Stark-induced transition polarizabilities in cesium
H. B. Tran Tan, D. Xiao, A. Derevianko
Extracting electroweak observables from experiments on atomic parity violation (APV) using the Stark interference technique requires accurate knowledge of transition polarizabiliti…
Precision theoretical determination of electric-dipole matrix elements in atomic cesium
H. B. Tran Tan, A. Derevianko
We compute the reduced electric-dipole matrix elements with and in cesium using the most complete to date ab initi…
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…
Parity-mixed coupled-cluster formalism for computing parity-violating amplitudes
H. B. Tran Tan, Di Xiao, A. Derevianko
We formulate a parity-mixed coupled-cluster (PM-CC) approach for high-precision calculations of parity non-conserving amplitudes in mono-valent atoms. Compared to the conventional…
