A nucleus having 4n number of nucleons, such as Be, C, O, etc., is theorised to possess
clusters of α particles (He nucleus). The Oxygen nucleus (O) has a double magic number, where the presence of an α-clustered nuclear structure grants additional nuclear stability. In this study, we exploit the anisotropic flow coefficients to discern the effects of an α clustered nuclear geometry w.r.t. a...
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
field...
Jet substructure measurements are a powerful tool that probe the parton shower differentially in regions of the QCD radiation phase space. They allow us to study the fragmentation patterns of parton showers in proton-proton collisions as well as their modification by the quark-gluon plasma (QGP) in heavy-ion collisions. Jet substructure can also be used to search for QGP-like modifications in...
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...
Crater experiments in laser research play a crucial role in advancing our understanding of laser-material interactions and optimizing various laser applications. These experiments involve directing high-intensity laser pulses at different materials to study the resulting craters' size, shape, and morphology. The primary purposes of these experiments include characterizing material properties...
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...
The standard model of modern cosmology, which is based on the Friedmann–Lemaître–Robertson–Walker metric, allows the definition of an absolute time. However, there exist (cosmological) models consistent with the theory of general relativity for which such a definition cannot be given since they offer the possibility for time travel. The simplest of these models is the cosmological solution...
Jupiter's magnetosphere is one of the largest natural particle accelerators in our Solar System. Its dynamic processes are governed by the fast rotation of the planet, creating complex current systems and particle transport mechanisms. The Galilean satellites play important roles as plasma sources, influencing the dynamics and distribution of charged particles in the Jovian magnetosphere....
