O fenômeno de quebra de simetria no modelo do oscilador anarmônico
Keywords:
dinâmica efetiva, quebra de simetria, oscilador anarmônico fermiônicoAbstract
Neste artigo, descrevemos através de uma técnica não-perturbativa o problema de condição inicial, no contexto da Mecânica Quântica, de um sistema fermiônico autointeragente fora do equilíbrio na presença de um campo magnético. Em particular, no regime de campo médio, estudamos o fenômeno de quebra dinâmica de simetrias neste sistema, identificando os processos físicos associados.
