Effects temperature, pressure and spin-orbit interaction simultaneously on third harmonic generation of wedge-shaped quantum dots

In the present paper, we have studied the effects of temperature and pressure simultaneously on the third harmonic generation (THG) of a GaAs wedge-shaped quantum dot under the influence of spin-orbit interaction (SOI). For this purpose, we have used analytical expression for THG obtained by the compact-density matrix formalism. THG has been calculated for different temperatures and pressures under SOI. According to the obtained results, it is found that (i) THG shows a red shift of peak position in the presence of SOI. (ii) THG shifts toward higher energies with increasing temperature and considering the SOI. (iii) THG moves to lower energies with increasing pressure and considering the SOI.
