Summary
We present an exactly solvable model describing the interaction between a two-level system and the electromagnetic field. For long interaction times we evidence some purely quantum-mechanical effects, such as the destruction of coherence of radiation and the Gaussian envelope of the transition probability.
Riassunto
Si espone un modello esattamente solubile per descrivere l’interazione fra un sistema a due livelli e il campo magnetico. Si mettono in luce, per lunghi tempi di interazione, certi effetti puramente quantistici, come la distruzione della coerenza di radiazione e l’inviluppo gaussiano della probabilità delle transizioni.
Резюме
Мы предлагаем точно решаемую модель, описывающую взаимодействие между двухуровневой системой и электромагнитным полем. Для больших времен взаимодействия мы подтверждаем некоторые чисто квантовомеханические эффекты, такие как нарушение когерентности изличения и гауссову фору огибающей вероятности перехода.
