Current and past research interests

I started to work on quark matter hadronization in 1995. I have developed a model called MICOR that is based on the assumption that constituent quark matter is created in high energy heavy ion collisions. The aim was to explain the experimental momentum spectra of hadrons in CERN SPS Pb+Pb and RHIC Au+Au collisions by a hadronization process similar to coalescence.

In 2000, I began working on a simplified model of rescattering processes, the pion wind model, using the GCP generic cascade program. In the same year, we started the development of a new general cascade code, called PSYCHE, with S. E. Vance and Y. Nara. In 2001, the RHIC Transport Theory Collaboration was formed, with our program in the center. The latest version of the program, called Gromit is even more general, not just the interactions, particles and initial conditions but also the cascade algorithm is definable. It can be used to perform a "full" secondary interaction simulation starting from arbitrary initial state. In my investigations, I used my hadronization model, MICOR, to generate the initial states.

In 2005, I created a high precision adaptive mesh refinement (AMR) code, called GridRipper. Initially, it was applied to simulate the time evolution of physical fields in flat space-time, such as the Klein-Gordon equation and the Yang-Mills-Higgs system. In general, the code is able to solve hyperbolic systems of partial differential equations using the chosen integration scheme (like RK2, RK4 or ICN). The initial condition is either defined by arbitrary formulae, generated by program code or produced as the numerical solution of an ordinary differential equation. In 2008, we found a new numerical framework with I. Rácz, which made it possible to follow the time evolution of the Einstein equations even after the appearance of trapped surfaces, until a singularity is reached. Based on this finding, I applied GridRipper in problems related to cosmic inflation and the gravitational collapse of fluids and scalar fields in spherical symmetry, leading to the birth of baby universes.
