“…28 Some enlightened theories were pro-posed to describe or guide these applications and experiments. In fact, the controllability of polariton devices has been theoretically attempted by several groups, 21,32,33 and for simplicity, the dependence of some polariton parameters on applied fields is neglected in their special problems. 31 Most of previous works both in theories and experiments are mainly focused on the polariton characters determined by the microcavity structures and pump geometries.…”

Excitons and polaritons in quasi-molecular eigenbasis of the excitation hopping system interacting with a photon fieldWe study the quantum-well magnetoexcitons by the variational method in the strong coupling regime of excitons with microcavity photons. In such strong coupling regime, we find that the coupling between the exciton internal state and center of mass motion can be neglected. Through the calculations, we find that the magnetic field can reduce the exciton exchange interaction to 30% as L w = 30 nm with L w being the quantum well width. This is in contrast to the magnetic-field enhancement in the exciton Rabi splitting. In this work, we obtain that a magnetic field can enhance the exciton Rabi splitting up to 1.6 times in the case of L w = 30 nm. They both originate from the local enhancement in the exciton internal state due to the magnetic field. In addition, we analyze the behavior of the magnetic response of the exciton energy, Rabi splitting, and exchange interaction in manipulating the polariton parametric scattering, and widening the microcavity applications.

“…These results will be used in the present study. Recently much attention was attracted to the experimental investigations of the influence of a perpendicular magnetic field on the cavity polaritons [12][13][14][15][16][17]. To the best of our knowledge, the strength of a magnetic field used in experimental studies did not exceed 14 Tesla.…”

Abstract. The energy spectrum of the 2D cavity magnetoexciton-polaritons has been investigated previously, using exact solutions for the Landau quantization of conduction electrons and heavy holes provided by the Rashba method [1]. Two lowest Landau quantization levels for electrons and three lowest Landau levels for heavy-holes, lead to the construction of the six lowest magnetoexciton sates. They consist of two dipole-active, two quadrupole-active, and the two forbidden quantum transitions from the ground state of the crystal to the magnetoexciton states. The interaction of the four optical-active magnetoexciton states with the cavity mode photons with a given circular polarization and with well-defined incidence direction leads to the creation of five magnetoexciton-polariton branches. The fifth order dispersion equation is examined by using numerical calculations and the second order dispersion equation is solved analytically, taking into account only one dipole-active magnetoexciton state. The effective polariton mass on the lower polariton branch, the Rabi frequency and the corresponding Hopfield coefficients are determined in dependence on the magnetic field strength, the Rashba spin-orbit coupling parameters and the electron and hole g-factors.

“…The polariton laser in the form of a diode with electron injection was constituted on this basis [9]. The influence of the external magnetic field on the cavity polaritons and on their BEC was investigated for the first time in [10][11][12][13][14]. But these studies were concerned the relatively small strength of the magnetic field, so that the electron structure of the Wannier-Mott excitons remains unchanged, causing only the diamagnetic and Zeeman splitting effects.…”

The properties of the two-dimensional cavity polaritons subjected to the action of a strong perpendicular magnetic and electric fields, giving rise to the Landau quantization (LQ) of the 2D electrons and holes accompanied by the Rashba spin-orbit coupling, by the Zeeman splitting and by the nonparabolicity of the heavy-hole dispersion law are investigated. We use the method proposed by Rashba [1] and the obtained results are based on the exact solutions for the eigenfunctions and for the eigenvalues of the Pauli-type Hamilonians with third order chirality terms and nonparabolic dispersion law for heavy-holes and with the first order chirality terms for electrons. The selection rules of the band-to-band optical quantum transitions as well as of the quantum transitions from the ground state of the crystal to the magnetoexciton states depend essentially on the numbers n e and n h of the LQ levels of the (e-h) pair forming the magnetoexciton. It is shown that the Rabi frequency Ω R of the polariton branches and the magnetoexciton oscillator strength f osc increase with the magnetic field strength B as Ω R ∼ √ B, and f osc ∼ B. The optical gyrotropy effects may be revealed changing the sign of the photon circular polarization at a given sign of the wave vector longitudinal projection k z or eqivalently changing the sign of k z at the same selected circular polarization.
