Interfaces in Numerical Relativistic hydrodynamics
… for modelling sharp interfaces<br/>between relativistic fluids. The motivation for this work lies in obtaining accurate<br/>models of neutron star interiors for use in multidimensional simulations<br/>in general relativity. The interior structure of a neutron star is believed to<br/>contain …

Causal and stable stochastic relativistic hydrodynamics
… on causal and stable formulations of stochastic relativistic hydrodynamics. Connections between causality, stability, and the foliation independence of equal-time fluctuations are used to formulate stochastic hydrodynamics in the linear regime. This approach is applied to several conventional …

The Discontinuous Galerkin Method applied on the equations of ideal relativistic hydrodynamics
To solve numerically the problems of ideal relativistic hydrodynamics we have developed a high-order accurate and time-explicite code. For the spatial discretisation we use the Discontinuous Galerkin Method (DGM). Numerical we studied the propagation of relativistic jets and the accretion onto …

Numerical solutions of the general relativistic equations for black hole fluid dynamics
… numerical solution of the equations of General Relativistic Hydrodynamics, to implement the algorithm in a computationally efficient manner, and to apply the resulting computer code to the problem of perturbed Bondi-Hoyle-Lyttleton accretion onto a Kerr black hole. The algorithm will also be …

Full 3+1 dimensional simulation of the relativistic Boltzmann equation
Relativistic hydrodynamics has been the tool of choice to simulate the dynamics of the quark-gluon plasma produced in heavy-ion collisions. Despite the success of hydrodynamics, it has several shortcomings stemming from the fact that it assumes a system close to equilibrium. An alternative to …

Second Order And Fluctuating Hydrodynamic Theory Of Two-Particle Transverse Momentum Correlations In Nuclear Collisions
<p>Relativistic heavy ion collision experiments show clear evidence of creation of a very short-lived phase of nuclear matter consisting of color-deconfined quarks and gluons. This matter is known as the quark-gluon plasma (QGP). Fluctuation and correlation measurements of the detected particles …

The trial of the holographic principle
… and conformal fluid dynamics. Foundations of relativistic hydrodynamics, conformal invariance, and geometry of anti-de Sitter spaces are discussed. We then detail an explicit calculation relating the dynamics of a non-stationary nonsymmetrical 3+1 dimensional black hole on an anti-de Sitter …

Signals of Collectivity in Heavy-Ion Collisions in the Far From Equilibrium Regime
… of the main observables in the field of ultra-relativistic heavy-ion collisions (HIC), which can be reproduced by theoretical descriptions from a realistically modelled initial stage.<br /><br /> In this thesis we see that it is possible - already by considering a few collisions - to translate …

Type I X-ray bursts as probes of the neutron star accretion flow
… a reflection code and post-processed general relativistic hydrodynamics simulation data of a disk being impacted by an X-ray burst to calculate how the reflection spectrum of an accretion disk evolves during an X-ray burst. The simulations of the third project examine the effect of neutron …

Finite system size effects on the effective coupling in scalar quantum field theory
… can be modeled well using nearly inviscid relativistic hydrodynamics. One would expect the equation of state (EOS) used in such hydrodynamic simulations to receive significant contributions in systems of size characteristic of p+p collisions. Indeed it has been shown that free scalar …

Cosmic Echoes of the Early Universe: From Primordial Black Holes to Gravitational Waves

Accurate numerical relativity simulations of non-vacuumspace-times in two dimensions and applications to critical collapse
… code will be developed, which solves the relativistic equations of hydrodynamics in axisymmetry. Therefore we consider an improved formulation of the conserved form of these equations. The second part will use the new code to investigate the critical behaviour of two colliding neutron …

Transport in a Strongly Coupled Charged Relativistic Quantum Fluid in the Presence of a Chiral Anomaly & a Strong Magnetic Field Via Hydrodynamics & Holography
Motivated by applications to the quark gluon plasma state generated in heavy ion collisions, I study a 4-dimensional supersymmetric conformal field theory in the thermal state, carrying axial charge, and subject to a strong external magnetic field, $B$. This theory has a chiral anomaly, which …
