We show that results for the thermodynamics of strongly interacting matter obtained by state of the
art Monte-Carlo simulations of lattice QCD can be adequately described within a generalized BethUhlenbeck type approach, where the hadron resonance gas (HRG) phase appears as a mixture of
(multi-) quark clusters. The underlying chiral quark dynamics is coupled to a background gluon

We deepen the understanding of the primordial composition of the Universe in the temperature range $130\,\mathrm{GeV}>T>0.02\,\mathrm{MeV}$ within the Big Bang model. Massive elementary particles: $t,b,c$-quarks, $\tau,\mu$-leptons, and $W, Z$-gauge bosons emerged at about $T=130\,\mathrm{GeV}$. These elementary particles in the following were abundantly present as the Universe expanded and...
Recent advances in laser technology and plasmonics, combined with knowledge from heavy-ion collisions, highlight the key role of resonating particles in boosting wave energy absorption, aiding fusion initiation.
In this study, we employ numerical modeling to investigate the interaction between laser radiation pulses and matter doped with gold nanoparticles of various shapes.
We investigate...
We develop a compact experimental setup to accelerate atoms from thin foils and gas targets. The energy and flux of plasma ions are measured with a Thomson parabola spectrometer and nuclear track detectors. We focus on the aneutronic p11B reaction which generates three energetic alpha particles. The yield of fusion products is measured with time-of-flight spectroscopy. We investigate the...
This study explores how gold nanoparticle doping enhances medium absorption under laser infrared pulses of intensities ~10^15 - 10^18 W/cm2. Traditionally, not the particle-in-cell method comes first in mind, however, we can also investigate effects which cannot be considered with common methods. Using numerical modeling and the EPOCH software, we investigate how nanoparticles of various...
