外文摘要：The axion,a theoretically well-motivated particle,has been searched for extensively via its hypothetical interactions with ordinary mat-ter and fields.Recently,a new axion detection approach has been considered utilizing the ultra-intense electromagnetic fields produced by laser-plasma interactions.However,a detailed simulation tool has not hitherto been available to help understand the axion-coupled laser-plasma interactions in such a complex environment.In this paper,we report a custom-developed particle-in-cell(PIC)simulation method that incorporates the axion field,the electromagnetic fields,and their interactions.The axion field equation and modified Maxwell's equations are numerically solved,with the axion-induced modulation of the electromagnetic field being treated as a first-order perturba-tion to handle the huge orders of magnitude difference between the two types of field.The simulation is benchmarked with well-studied effects such as axion-photon conversion and the propagation of an extremely weak laser pulse in a magnetized plasma.Such an extended PIC simulation provides a powerful tool to study axions under ultra-intense electromagnetic fields in the laboratory or in astrophysical processes.
