-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…
Coherently Enhanced Axion-Photon Conversion via Seeded Photons for Short-Pulse Axion Detection
Xiangyan An, Min Chen, Jianglai Liu +7
We propose a seeded axion-photon conversion scheme to enhance the sensitivity of light-shining-through-a-wall (LSW) experiments for axion detection, where the axions are generated…
Acceleration of Ultrahigh Energy Particles from Fast Radio Bursts
Lin Yu, Tianxing Hu, Zhiyu Lei +6
Two extreme events in the universe, fast radio bursts (FRBs) and cosmic rays (CRs), could be correlated, where FRBs with extreme field strength near their sources may contribute to…
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…
Cosmology with the angular cross-correlation of gravitational-wave and galaxy catalogs: Forecasts for next-generation interferometers and the Euclid survey
Alessandro Pedrotti, Michele Mancarella, Julien Bel +2
The spatial clustering of galaxies has long been a key probe of cosmology. Gravitational-wave (GW) sources, which provide direct luminosity-distance measurements, have recently eme…
