作者：余同普 alexander Pukhov 盛政明刘峰 Gennady Shvets Department of Physics National University of Defense Technology State Key Laboratory of High Performance Computing National University of Defense Technology Institut für Theoretische Physik I Heinrich-Heine-Universitt Düsseldorf Institut für Theoretische Physik I Heinrich-Heine-Universitt Düsseldorf Key Laboratory for Laser Plasmas(MoE) and Department of Physics Shanghai Jiao Tong University Institut für Laser-und Plasmaphysik Heinrich-Heine-Universitt Düsseldorf Department of Physics The University of Texas at Austin

By using multidimensional particle-in-cell simulations, we study the electromagnetic emission from radiation pressure acceleration of ultrathin mass-limited foils. When a circularly polarized laser pulse irradiates the foil, the laser radiation pressure pushes the foil forward as a whole. The outer wings of the pulse continue to propagate and act as a natural undulator. Electrons move together with ions longitudinally but oscillate around the latter transversely, forming a self-organized helical electron bunch. When the electron oscillation frequency coincides with the laser frequency as witnessed by the electron,betatronlike resonance occurs. The emitted x rays by the resonant electrons have high brightness, short durations, and broad band ranges which may have diverse applications.

Over the last two decades,computational methods have made tremendous advances,and today many key properties of lithium-ion batteries can be accurately predicted by first principles *** this reason,computations have become a cornerstone of battery-related research by providing insight into fundamental processes that are not otherwise accessible,such as ionic diffusion mechanisms and electronic structure effects,as well as a quantitative comparison with experimental *** aim of this review is to provide an overview of state-of-the-art ab initio approaches for the modelling of battery *** consider techniques for the computation of equilibrium cell voltages,0-Kelvin and finite-temperature voltage profiles,ionic mobility and thermal and electrolyte *** strengths and weaknesses of different electronic structure methods,such as DFT+U and hybrid functionals,are discussed in the context of voltage and phase diagram predictions,and we review the merits of lattice models for the evaluation of finite-temperature thermodynamics and *** such a complete set of methods at hand,first principles calculations of ordered,crystalline solids,i.e.,of most electrode materials and solid electrolytes,have become reliable and ***,the description of molecular materials and disordered or amorphous phases remains an important *** highlight recent exciting progress in this area,especially regarding the modelling of organic electrolytes and solid–electrolyte interfaces.
