On a sensitive ellipsometer to detect the vacuum polarization induced by a magnetic field

О чуствителяном эллипсометре для определения поляризации вакуума, индуцированной магнитным полем

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

An ellipsometer able to measure ellipticities down to 10−11 is being developed. We present here results of measurements made in order to test the main parts of the apparatus. The feasibility and the limits of such an ellipsometer are discussed, in particular in view of measuring the polarization of the vacuum induced by a magnetic field (photon-photon interaction).

Riassunto

In questo articolo si presentano i risultati di misure fatte allo scopo di mettere a punto un ellipsometro capace di misurare ellitticità dell’ordine di 10−11. Il metodo descritto è stato sviluppato principalmente allo scopo di misurare la polarizzazione del vuoto indotta da un forte campo magnetico (interazione fotone-fotone).

Резюме

Предлагается эллипсометр, позволяющий измерить эллиптичности вплоть до 10−11. Приводятся результаты измерений, проведенных с целью проверки основных частей аппаратуры. Обсуждаются осуществимость и ограничения такого эллипсометра, в частности, применительно для измерения поляризации вакуума, индуцированной магнитным полем (фотон-фотонное взаимодействие).
