Electro-optical properties of Cu2O for P excitons in the regime of Franz-Keldysh oscillations

Magneto-excitons in Cu2O: theoretical model from weak to high magnetic fields

“…In the case of Cu 2 O ν means p, f, h, K excitonic states. The equations have been described in [2,6] (see also [11,16]) and have the form…”

“…Again, note that transition to intermediate field regime is earlier for higher states. We have to remark that for these two regimes of magnetic field, we use two different methods of solution of the constitutive equation (2) and as the consequence one can not expect interpolation to be perfect. For the weak field we have used the perturbation calculus, where the unperturbed, spherically symmetric eigen-functions serve as a basis.…”

“…Extraordinary properties of RE attracted an increasing attention during the last few years, specifically for excitons in high external magnetic fields ( [2][3][4][5][6] and references therein). This model system is well-recognized as a convenient analog to a hydrogen atom, in which the high field' physics occurs already at moderate field strengths achievable in a laboratory.…”

“…The upper value corresponds to B>0 and m=−1, and the lower to the quantum number m=+1 for the same field orientation.The Green's function allows one to calculate the amplitude Y from the (16)  is the amplitude of the propagating wave and M the dipole density in scaled variables. The detailed calculations follow the pattern presented for the electric field using the trial wave functions[2]. For p excitons the trial function has the form[11] Y nm (ζ).…”

“…For p excitons the trial function has the form[11] Y nm (ζ). Furthermore, the y component of the dipole density of the form[2]…”
