PY - 2018 TI - Magnetic Field Effects for the Emission Spectra in a Microcavity-Quantum Dot System JF - Revista Cubana de Física; Vol 35 No 2 (2018) KW - N2 - The behaviour of the photoluminescence spectra of a single quantum dot in a semiconductor microcavity is modeled numerically in the presence of an external and constant magnetic field. The dynamics of the density operator is calculated using the master equation in the Lindblad form for decoherence processes: spontaneous emission, losses through cavity mirrors, and dephasing. An incoherent pumping of excitons is used to feed the system. It is found in the photoluminescence spectra that for magnetic fields lower than 2 T the system is in the strong coupling regime and for magnetic fields greater than 2 T the system emits light like three independent systems. The line that uncouples faster is the σ line. UR - http://revistacubanadefisica.org/index.php/rcf/article/view?path=
