Relativistically-intense laser beam with large field gradient ("laser gate") enables strong inelastic scattering of electrons crossing the beam. This process allows for multi-MeV electron net acceleration per pass within the wavelength space. Inelastic scattering even in low-gradient laser field may also induce extremely tight temporal focusing and electron bunch formation down to quantum, zept...

A QCD analysis of jet production in deep-inelastic scattering is presented. The studies are based on recent measurements of jet cross sections in the H1 experiment at HERA which are directly sensitive to the gluon density in the proton. The inclusion of H1 data on the inclusive deep-inelastic scattering cross section enables us to perform a consistent, simultaneous determination of the quark an...

Gases of inelastically colliding particles model the dynamics of granular materials [1,2], geophysical flows [3], and large-scale structure of matter in the universe [4]. Typically, a fraction of the kinetic energy is dissipated in each collision, leading to interparticle velocity correlations, a clustering instability [5–9], and in the absence of external energy input, an inelastic collapse [1...
