  2. 1. Compact Relativistic Matter Shells with Massless and Charged Particles

    Author : Maximilian Thaller; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spherical Symmetry; massless Einstein-Vlasov system; Einstein-Vlasov-Maxwell system; Static Solutions; Vlasov matter; General Relativity; Einstein-Vlasov-Maxwell system;

    Abstract : The Vlasov model is a matter model that is widely used in physics. In the context of astrophysics and cosmology it describes an ensemble of self gravitating, collisionless particles. These particles can be interpreted as for example ions, stars, or galaxies. READ MORE

  4. 2. On the Einstein-Vlasov system: Stationary Solutions and Small Data Solutions with Charged and Massless Particles

    Author : Maximilian Thaller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Static Solutions; Vector Field Method; non-linear wave equation; massless Einstein-Vlasov system; General Relativity; Conformal Einstein Field Equations; Minkowski stability; Vlasov matter; symmetric hyperbolic system; Einstein-Vlasov-Maxwell system;

    Abstract : The Vlasov matter model describes an ensemble of collisionless particles moving through space-time. These particles interact via the gravitational field which they create collectively. In the framework of General Relativity this gravitational field is described by space-time curvature. READ MORE

  5. 3. On the cylindrically symmetric Einstein-Vlasov system

    Author : Mikael Fjällborg; []
    Keywords : ;

    Abstract : For the cylindrically symmetric ''asymptotically flat'' Einstein equations in the case of electro-vacuum it is known that solutions exist globally and even that this class of spacetimes are causally geodesically complete. Hence the strong cosmic censorship holds for this class. READ MORE

  6. 4. Modelling of laser plasma interaction with applications to particle acceleration and radiation generation

    Author : Benjamin Svedung Wettervik; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasma; ion acceleration; continuum methods; electron wakefield acceleration; raditation generation; coherent X-ray pulses; Vlasov-Maxwell equations;

    Abstract : The development of laser systems with ultra-high intensities has allowed the study of the relativistic interaction of laser light and ionized matter, plasmas, as well as opened up prospects for compact particle accelerators, generation of high intensity X-ray, XUV radiation, and probing QED-effects, which are present in the high intensity regime. To describe laser matter interaction, it is necessary to self-consistently account for the paths of a large number of particles and the corresponding electromagnetic fields, with the addition of stochastic effects at high laser intensities.

  7. 5. Modelling of laser plasma interaction with applications

    Author : Benjamin Svedung Wettervik; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electron wakefield acceleration; ion acceleration; coherent X-ray pulses; plasma; Vlasov-Maxwell equations; continuum methods; radiation generation;

    Abstract : The development of laser systems with ultra-high intensities has both opened up prospects for compact particle accelerators, as well as probing QED-effects, which are present in the high intensity regime. To describe laser matter interaction, it is necessary to self-consistently account for the paths of a large number of particles and the corresponding electromagnetic fields, with the addition of stochastic effects at high laser intensities.
