Hamiltonian reductions for modeling relativistic laser-plasma interactions

We show two applications of Hamiltonian reductions related to relativistic laser-plasma interactions starting from the Vlasov–Maxwell equation. The use of the Hamiltonian formalism ensures a consistent asymptotic ordering and results in reduced models that maximally preserve the structure of Vlasov–Maxwell system.

► We examine Hamiltonian reductions of the Vlasov–Maxwell system. ► We demonstrate a fluid-like reduction without a closure. ► We construct a self-consistent moment-based description of a beam-plasma system.
