Course Objectives The course will cover in-depth quantum mechanical treatments and related calculation methods necessary for understanding atomic, molecular, optical, solid state, particle, and many-body systems. Topics:-Hydrogen-like atoms, fine and hyperfine structure.-Stark effect and Zeeman effect.- Time-independent perturbation theory.-Variational method.

The Stark effect is the phenomena of altering atomic energy levels by an external electric field. The external electric field can be applied to an atom or molecule and acts as a perturbation. This effect, though small compared to the spacings between the unperturbed atomic levels, is quite significant. The Stark effect can be readily observed as In the effect the energy levels of hydrogen for weak fields split proportionally to the first power of the field strength (the so-called linear Stark effect). This phenomenon was experimentally shown by Stark from the Balmer series in 1913.

Stark effect quantum mechanics

There are four such states: an l = 0 state, usually referred to as 2 S, and three l = 1 states (with m = − 1, 0, 1), usually referred to as 2P. Stark effect in hydrogen Johannes Stark (15 April 1874 – 21 June 1957) was a German physicist, Introduction to Quantum Mechanics Stark effect The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external static electric field. The amount of splitting and or shifting is called the Stark splitting or Stark shift. In general one distinguishes first- and second-order Stark effects. 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. This study completes the understanding at a fundamental level to understand the well known Stark effect. Doi: 10.28991/esj-2020-01242 The old quantum theory and Schrödinger's wave mechanics (and other forms of quantum mechanics) give the same results for the line splittings in the first-order Stark effect in hydrogen, the leading terms in the splitting of the spectral lines emitted by a hydrogen atom in an external electric field.

Quantum mechanical predictions of this effect are extremely accurate, a fact that provided compelling early evidence for quantum mechanics. The Stark effect is

If you expose an atomic 2-level system to a time dependent periodic electromagnetic wave, according to the AC-Stark effect (or Autler-Townes Effect) we experience an energy shift of the quantum system. I always understood an energy shift to be a shift of the energies of the eigenstates of the system. DOI: 10.4236/jqis.2019.91003 25 Journal of Quantum Information Science The Stark effect is investigated for the Dicke Hamiltonian in the presence of constant fields and hence shifting in eigenvalues is observed due to the t- emi ter-cavity interaction strength.
