1. Estudo do acoplamento spin-órbita de multipartículas confinadas em pontos quânticos semicondutores
Spin-orbit (SO) coupling provides a way for orbital degrees of freedom to influence spin states. As a result the spin dynamics is affected, thus making spin qubit (quantum version of bit, basic unit of information in the computational language) operations more complex. Furthermore, spin-orbit coupling leads to spin decoherence and relaxation due to phonons,

2. Excitonic emission of a triply charged quantum dot molecule in a magnetic field
We calculate the exciton states of a Quantum Dot (QD) and a Quantum Dot Molecule (QDM) in an exact way for single, double and triply charged excitons without and with an applied external magnetic field. For the case of single quantum dot, we reproduce the experimental results reported in [2]. We also calculate the emission energies for the neutral molecule Q
