In 2004, Alex Zettl used boron-nitride nanotubes to observe a "giant" variety of this effect, and the Autler-Townes effect is an AC version of it. A low-energy tail in the absorption edge of semiconductor spectra known as the Franz-Keldysh effect is related to one type of this effect; that type results in an increase in interband separation and a decrease in exciton binding energy, and is known as the quantum-confined variety.

According to Kramers' theorem, this effect can only break degeneracy completely for a system in which the sum of the particle spins has an integral value. The linear version of this effect can only exists for degenerate states that are not parity eigenstates, while for non-degenerate states, only the quadratic variety exists. Analogous to the Zeeman effect, for ten points, identify this quantum-mechanical effect in which spectral lines are split by an applied electric field.
