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…
A Low-Noise High-Density Alkali Metal Scalar Magnetometer
S. J. Smullin, I. M. Savukov, G. Vasilakis +2
We present an experimental and theoretical study of a scalar atomic magnetometer using an oscillating field-driven Zeeman resonance in a high-density optically-pumped potassium vap…
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…
Multipole (E1, M1, E2, M2) transition wavelengths and rates between states with n<= 6 in heliumlike carbon, nitrogen, oxygen, neon, silicon, and argon
I. M. Savukov, W. R. Johnson, U. I. Safronova
Transition wavelengths and rates are given for E1, E2, M1, and M2 transitions between singlet and triplet S, P, D, and F states in heliumlike ions of astrophysical interest: carbon…
E1 transitions between states with n = 1 to 6 in helium-like carbon, nitrogen, oxygen, neon, silicon, and argon
W. R. Johnson, I. M. Savukov, U. I. Safronova +1
Wavelengths and transition rates are given for E1 transitions between singlet S, P, D, and F states, between triplet S, P, and D states, and between triplet P and singlet S states…
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…
