We analyze the inelastic electron-electron scattering in undoped graphene within the Keldysh
diagrammatic approach. We demonstrate that finite temperature strongly affects the screening
properties o...

We study the time-dependence of the magnetization profile, ml(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with an exponentially decr...
