High-density Optical Quantum Sensors with Pulsed Probe Read-out for Correlated Spin-Noise Reduction
Igor Savukov, Young Jin Kim
Optical quantum sensors based on alkali-metal atoms enable highly sensitive magnetic-field measurements at room temperature. Their ultimate performance is limited by intrinsic spin…
Defect assignment of the clock site in
Daniel A. Rehn, Harry W. T. Morgan, Harris E. Mason +6
The performance of solid-state nuclear clocks depends sensitively on the microscopic environment of the thorium nucleus in the host crystal. Here we reassess the…
Parametrical CI+MBPT calculations of Th I energies and -factors for even states
I. M. Savukov
In this paper, we study energies and -factors for a large number of levels of Th I. We found that the accuracy of CI-MBPT can be substantially improved by using multiple adjustm…
Third-order relativistic many-body calculations of energies and lifetimes of levels along the silver isoelectronic sequence
U. I. Safronova, I. M. Savukov, M. S. Safronova +1
Energies of 5l_j (l= s, p, d, f, g) and 4f_j states in neutral Ag and Ag-like ions with nuclear charges Z = 48 - 100 are calculated using relativistic many-body perturbation theory…
Energies, transition rates, and electron electric dipole moment enhancement factors for Ce IV and Pr V
I. M. Savukov, W. R. Johnson, U. I. Safronova +1
Energies, transition rates, and electron electric dipole moment (EDM) enhancement factors are calculated for low-lying states of Ce IV and Pr V using relativistic many-body perturb…
Mixed configuration-interaction and many-body perturbation theory calculations of energies and oscillator strengths of J=1 odd states of neon
I. M. Savukov, W. R. Johnson, H. G. Berry
Ab-initio theory is developed for energies of J=1 particle-hole states of neutral neon and for oscillator strengths of transitions from such states to the J=0 ground state. Hole en…
Measurement of the 6s - 7p transition probabilities in atomic cesium and a revised value for the weak charge Q_W
A. A. Vasilyev, I. M. Savukov, M. S. Safronova +1
We have measured the 6s - 7p_{1/2,3/2} transition probabilities in atomic cesium using a direct absorption technique. We use our result plus other previously measured transition ra…
Large Contributions of Negative Energy States to Forbidden Magnetic-Dipole Transition Amplitudes in Alkali-Metal Atoms
I. M. Savukov, A. Derevianko, H. G. Berry +1
The influence of negative-energy states (NES) on forbidden magnetic-dipole transitions in alkali-metal atoms is investigated. We find that the NES contribut…
