Modified paisley target configuration for magnetic reconnection in laser-plasma interactions

Abstract

High-intensity laser-target interaction generates strong magnetic fields that enable the study of magnetic reconnection. This paper introduces a novel modified paisley target with a central cavity that induces opposing magnetic fields for potential magnetic reconnection. Using particle-in-cell (PIC) simulations via the EPOCH code, we analyzed the plasma dynamics under relativistic laser irradiation. Our results show strong, oppositely directed magnetic fields and high current densities near the cavity, characteristic of reconnection-prone regions. Comparative studies with alternative targets support the efficiency of the modified paisley target configuration. Further three-dimensional simulations are needed to confirm reconnection dynamics.
