Self-Seeded Free-Electron Lasers with Orbital Angular Momentum
Jiawei Yan, Gianluca Geloni
X-ray beams carrying orbital angular momentum (OAM) are an emerging tool for probing matter. Optical elements, such as spiral phase plates and zone plates, have been widely used to…
High-repetition-rate seeded free-electron laser enhanced by self-modulation
Hanxiang Yang, Jiawei Yan, Haixiao Deng
Recently, the self-modulation scheme of a weakly pre-bunched electron beam has been proposed [Yan et al., Physical Review Letters 126, 084801 (2021)], which is of great promise for…
Optimization and stability analysis of the cascaded EEHG-HGHG free-electron laser
Hanxiang Yang, Jiawei Yan, Zihan Zhu +1
X-ray free-electron lasers (XFELs) are powerful tools to explore and study nature for achieving remarkable advances. Generally, seeded FELs are ideal sources for supplying full coh…
Physics-informed graph neural networks enhance scalability of variational nonequilibrium optimal control
Jiawei Yan, Grant M. Rotskoff
When a physical system is driven away from equilibrium, the statistical distribution of its dynamical trajectories informs many of its physical properties. Characterizing the natur…
