The shift of the molecular energy levels due to the perturbation is the dc Stark effect. The authors illustrate the dc Stark effect for a molecule in the 1 Σ electronic state. They take the constant electric field vector outside the matrix elements to express the perturbations in terms of the molecule‐specific matrix elements of the dipole moment operator.

ac-Stark Shifting the qubit. In order to ac-Stark shift the qubit we need to populate the resonator with photons using an on-resonance drive. For a drive amplitude $\epsilon$, and a resonator decay rate of $\kappa$, the number of photons in the resonator $\bar{n}=\langle a^\dagger a \rangle = \frac{\epsilon^2}{\Delta^2 +(\kappa/2)^2}$. As first shown by Boxer et al. electroabsorption (or Stark effect) spectroscopy provides an experimental method to determine the extent of delocalization in mixed- 8 Jan 2016 A last comment concerning the perturbation theory, is that we will use the ground state solution for the unperturbed Hamiltonian, [Privman, 1980], The quadratic Stark effect in the ground state of alkali atoms, treated in the frame of 2.1.2 The Stark hamiltonian in terms of irreducible tensor components .

We define an atomic system consisting of two states (a ground state labeled 1 and upper state labeled 2). The Zeeman effect, named after Dutch physicist Pieter Zeeman, is the effect of splitting of a spectral line into several components in the presence of a static magnetic field. It is analogous to the Stark effect, the splitting of a spectral line into several components in the presence of an electric field. Also similar to the Stark effect, transitions between different components have, in general, different intensities, with some being entirely forbidden, as governed by the Question: (6) The Stark Effect Suppose That Our Unperturbed Hamiltonian Is The Hydrogen Atom Without Any Fine Structure Or Other Corrections.

The Hamiltonian of the system can be split into two parts. Namely, the unperturbed Hamiltonian, Returning to the Stark effect, let us examine the effect of an external electric field on the energy levels of the states of a hydrogen atom.
