Summary
The quantum behaviour of a scalar test field is described in a massive true vacuum bubble space-time. It is shown that, if we take into account the cosmological-medium contribution, the expectation value of the stress energy tensor of the test field is regular at every instant of the bubble evolution.
Riassunto
Si descrive il comportamento quantistico di un campo scalare di test nello spazio-tempo di una bolla massiva di vero vuoto. Si mostra che se si tien conto del contributo del mezzo cosmologico, il valore d’aspettazione sul vuoto del tensore energia impulso del campo di test è regolare ad ogni istante dell’evoluzione della bolla.
Резюме
Описывается квантовое поведение скалярного пробного поля в пространстве-времени пузырька массивного истинного вакуума. Показывается, что если мы учитываем космологический вклад среды, то величина ожидания в вакууме для тензора энергии-импульса пробного поля является регулярной для каждого момента эволюции пузырька.
