Item Dinâmica populacional em sistemas atômicos de dois e três níveis de energia(Universidade Federal de Goiás, 2017-08-10) Alves, Eyber Domingos; Almeida, Norton Gomes de; http://lattes.cnpq.br/3182841849332242; Oliveira, Guilherme Colherinhas de; Almeida, Agnaldo Rosa deIn this work a description of the interaction between electromagnetic radiation and matter will be made. Two and three-level atomic systems will be addressed, which in turn is in the (Lambda) configuration.We will use the Dicke states to calculate the transition probability between the energetic levels for a 2-level ensemble of atoms interacting with a circularly polarized field. We will deduce the master equation for a two-level atom interacting with a thermal reservoir, observing the effects of irreversible spontaneous decay and loss of coherence between quantum states. Finally, we will study the phenomenon of Electromagnetically Induced Transparency (EIT) and Dark states.
