Abstract: Radiative corrections to electronic structure are characterized by perturbative expansions in $\alpha$ and $Z\alpha$, where $\alpha$ is the fine-structure constant and $Z$ is the nuclear charge. A formulation of the leading-order $\alpha(Z\alpha)$ Uehling contribution to the renormalized vacuum polarization is reported in a form that is convenient for implementation in computational studies of the relativistic electronic structures of molecules. Benchmark calculations based on these methods are reported that include the leading-order vacuum polarization effects within relativistic mean-field methods for the E119$^+$ ion and the closed-shell diatomic species E119F.

Hadronic vacuum polarization correction to the bound-electron $g$ factor [0.0]
The hadronic vacuum polarization correction to the $g$ factor of a bound electron is investigated theoretically. In heavy ions, such effects are found to be much larger than for the free-electron $g$ factor.

Computational Insights into Electronic Excitations, Spin-Orbit Coupling Effects, and Spin Decoherence in Cr(IV)-based Molecular Qubits [63.18666008322476]
We provide insights into key properties of Cr(IV)-based molecules aimed at assisting chemical design of efficient molecular qubits. We find that the sign of the uniaxial zero-field splitting (ZFS) parameter is negative for all considered molecules. We quantify (super)hyperfine coupling to the $53$Cr nuclear spin and to the $13C and $1H nuclear spins.

corrections to the $g$ factor of hydrogenlike ions are calculated without expansion in the nuclear binding field. The total correction to the $g$ factor coming from all diagrams considered in this work is found to be highly relevant for upcoming experimental tests of fundamental physics with highly charged ions.

We show that in an appropriately weighted difference of the bound-electron $g$ factor and the ground state energy, nuclear structural effects can be effectively suppressed.

Anisotropy-mediated reentrant localization [62.997667081978825]
We consider a 2d dipolar system, $d=2$, with the generalized dipole-dipole interaction $sim r-a$, and the power $a$ controlled experimentally in trapped-ion or Rydberg-atom systems. We show that the spatially homogeneous tilt $beta$ of the dipoles giving rise to the anisotropic dipole exchange leads to the non-trivial reentrant localization beyond the locator expansion.
