Enhancement of pair production in oscillated overlapped fields

Year: 2024

Type: article

Abstract: The electron-positron pair production has been investigated in two overlapped potential wells with varied widths and frequencies. Notably, specific multiphoton absorption processes exhibit distinct changes, the total number of created pairs increases linearly, and appears in periodic oscillation with the spatial extends of the potential wells. Furthermore, the investigation revealed the crucial impact of the smaller frequency on the pair production yield. The optimal combination of frequencies was determined to enhance the creation of pairs in overlapped fields. These findings provide valuable insights into the dynamics of multiphoton absorption processes and offer a pathway toward maximizing pair creation in complex potential landscapes.
