The recoil-in-vacuum (RIV) [1] is a method utilizing hyperfine interaction to measure the nuclear g factors for excited states with pico-second lifetimes. It has drawn a lot of attentions recently because of advantages over transient field (TF) method for applications to radioactive beams. The RIV was first introduced in the 1970’s but was seldom used due to the difficulty in calibrating the hy...

Microwave-induced changes in the optical emission of the NV center in diamond have previously been attributed to magnetic resonance of the defect in its A ground state [E. van Oort et al. , J. Phys. C 21, 4385 (1988)]. In this paper, the focus is on the origin of the hyperfine splittings that are observed in the optically detected magnetic-resonance (ODMR) spectra at zero and low magnetic field...

We study the deterministic entanglement of a pair of neutral atoms trapped in an optical lattice by coupling to excited-state molecular hyperfine potentials. Information can be encoded in the ground-state hyperfine levels and processed by bringing atoms together pair-wise to perform quantum logical operations through induced electric dipole-dipole interactions. The possibility of executing both...

Theoretical investigations of the hyperfine structure of the hydrogen molecular ion (one electron and two protons) are discussed. The nuclear spin-rotation interaction has been found to be of the same sign as in the hydrogen molecule and the hyperfine transition frequencies can be accurately predicted. With measurements of the hyperfine structure of the deuterium molecular ion (or of HD) it sho...

The nuclear spin–rotation interaction in the hyperfine structure of the hydrogen molecular ion is investigated. The interaction constants are determined and are found to differ in sign and magnitude compared to another theory, but they are in agreement with some values derived from experiment.

The hyperfine structure of the long-lived 5D3/2 and 5D5/2 levels of Ba + ion is analyzed. A procedure for extracting relatively unexplored nuclear magnetic moments is presented. The relevant electronic matrix elements are computed in the framework of the ab initio relativistic many-body perturbation theory. Both the firstand the second-order in the hyperfine interaction corrections to the energ...

By combining our theoretical calculation and recently measured electric quadrupole hyperfine structure constant of the 3d 2 D 5/2 state in the singly ionized 43 Ca, we determine its nuclear quadrupole moment to one percent accuracy. The obtained result, −0.0444(6)b, is about ten percent improvement over the considered standard value. We have employed the relativistic coupled-cluster theory at s...

We theoretically investigate the spin dynamics of a heavy hole confined to an unstrained III-V semiconductor quantum dot and interacting with a narrowed nuclear-spin bath. We show that band hybridization leads to an exponential decay of hole-spin superpositions due to hyperfine-mediated nuclear pair flips, and that the accordant single-hole-spin decoherence time T2 can be tuned over many orders...

Two fermion relativistic bound states: hyperfine shifts. Abstract We discuss the hyperfine shifts of the Positronium levels in a relativistic framework, starting from a two fermion wave equation where, in addition to the Coulomb potential, the magnetic interaction between spins is described by a Breit term. We write the system of four first order differential equations describing this model. We...
