-dispersionless solver for electromagnetic and axion fields in a cylindrical particle-in-cell code
Xiangyan An, Min Chen, Yipeng Wu +3
We develop a quasi-cylindrical direction-splitting (QDS) dispersionless Maxwell solver for the open-source EPOCH particle-in-cell framework. The method preserves the exact axial ph…
Chirped-Pulse Forward Raman Amplification in Nonuniform Plasmas
Zhi-Yu Lei, Zheng-Ming Sheng, Su-Ming Weng +2
Light amplification via Raman scattering in plasma has been severely constrained by stringent phase matching conditions and the need for plasma uniformity. To overcome these limita…
Generating intense attosecond pulses and vectorizing polarization states from laser-plasma interactions
Panfei Geng, Yipeng Wu, Zhixin Fan +7
Vector beams with spatially structured polarization and intertwined spin-orbital angular momentum (SAM-OAM) provide powerful degrees of freedom for tailoring light-matter interacti…
Gigagauss magnetic fields generated via theta-pinching driven by multiple petawatt-class lasers
Huanyu Song, Zhengming Sheng, Linzheng Wang +4
Extremely high axial magnetic fields above the gigagauss (GG) level are supposed to exist in neutron stars, which may be a one of the critical parameters for their internal structu…
Generation of high power spatially-structured laser pulses via forward Raman amplification in plasma
Zhi-Yu Lei, Su-Ming Weng, Min Chen +2
Spatially-structured light with tunable intensity, wavelength, and spatiotemporal profiles has demonstrated significant potentials for fundamental and applied science, including th…
