2. THEORY OF THE OPTI CAL STARK EFFECT The physics of the optical Stark effect can be presented semi -classically by a Hamiltonian in which light is represented by classical fields as external perturbation. The perturbed Hamiltonian can be diagonalized to obtain the altered energy levels, and the optical Stark effect can be perceived from the

There is a single state, usually referred to as , and three states (with ), usually referred to as . All of these states possess the same energy, . As in Section 7.4, the perturbing Hamiltonian is 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. The magnitude of the permanent dipole moment is conventionally measured A formula for the energy shifts due to an optical field is obtained for a two-level atomic system. This loads the package. We define an atomic system consisting of two states (a ground state labeled 1 and upper state labeled 2).

The perturbed Hamiltonian can be diagonalized to obtain the altered energy levels, and the optical Stark effect can be perceived from the induced change of the energy spectrum. The Stark effect does not provide the signs of the dipole components, and therefore the direction must be obtained from other information, such as electronegativities.

## Consider again the Stark effect Hamiltonian (1.1): H = H(F) =-Δ- Zlr + 2Fx 3. (2.1) It is well known [12,17] that the partial differential expression (2.1) can be realized

Finally, the non-Hermitian aspect has been introduced to the well known Stark effect in quantum mechanics to find a condition in which the Stark effect will still be true even if a non-Hermitian Hamiltonian is used. The Hamiltonian for this perturbation in atomic units is: \[H^{\prime}= εz,\] which in spherical polar coordinates is: \[H^{\prime} = ε r\cos(θ),\] where \(ε\) is the electric field strength. In this perturbation method treatment the hydrogen atom eigenfunctions are used to evaluate the matrix elements associated with the total Hamiltonian, 11.5: Quadratic Stark Effect.

As before, the perturbing Hamiltonian is We compute the Stark eﬀect on atomic hydrogen using perturbation theory by diagonalizing the perturbation term in the N2-fold degenerate multiplet of states with principal quantum number N. We exploit the symmetries of this problem to simplify the numerical computations. In particular, after assuming the N′-Nmatrix elements of the hamiltonian The Stark effect does not provide the signs of the dipole components, and therefore the direction must be obtained from other information, such as electronegativities. However, the effect of isotopic substitution, where the primary effect is to rotate the principal axis system, has been used to specify the directions of the dipole components and hence μ. In spectroscopy, the Autler–Townes effect, is a type of dynamical Stark effects corresponding to the case when an oscillating electric field is tuned in resonance to the transition frequency of a given spectral line, and resulting in a change of the shape of the absorption/emission spectra of that spectral line. The AC stark effect was discovered in 1955 by American physicists Stanley Autler and Charles Townes. It is the AC equivalent of the Stark effect which splits the HAMILTONIAN WITH STARK EFFECT: NON-EXISTENCE OF BOUND STATES AND RESOLVENT ESTIMATE HIDEO TAMURA (Received November 13, 1991) Introduction The present work is a continuation to [16], in which the author has proved the asymptotic completeness of wave operators for three-particle Stark Hamil-tonians.

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.
