5 From hadron resonance gas to quark-gluon plasma by Mott dissociation of quark clusters

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 using the Polyakov gauge. The transition to the quark-gluon plasma (QGP) phase appears as a
Mott dissociation of the quark clusters described by a model for hadron phase shifts that encodes
the dissociation of bound states in the continuum of scattering states triggered by the chiral
symmetry restoration transition. An important ingredient are Polyakov-loop generalized distribution
functions of multi-quark clusters which are derived here for the first time [1].
This new approach gives a quantitative understanding for the observation of ultrarelativistic heavyion collision that the abundances of hadrons produced in these experiments are well described by a
statistical model within a sudden chemical freeze-out at a well-defined hadronization temperature
despite the fact that the melting of the chiral condensate proceeds as a smooth crossover.
We report for the first time the remarkable finding that the ratio of generalized baryon number
susceptibilities $R_{42}^B(T)=\chi_4^B (T)/\chi_2^B (T)$, which interpolates between the value
$R_{42}^B(T\simeq 140 {\rm MeV})=1$ for a pure HRG and
$R_{42}^B(T>250 {\rm MeV}) \sim1/9 $ for the QGP shall not be mistaken for a measure of the
fraction of hadrons in the system. Its deviation from unity can actually quantify the degree of
overlap of quark wave functions which leads to the quark Pauli blocking effect in the HRG which
leads to repulsive residual interactions which we model by a temperature dependent excluded
baryon volume.

Particles in Strong Fields

12 Elementary Particles and Plasmas in the first hour of the early Universe

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 cooled - our interest is to search for periods of possible chemical non-equilibrium of great importance in baryogenesis. Once the temperature dropped below $T=150$\,~MeV quarks and gluons hadronize into matter. We follow the Universe evolution in depth and study near $T=\mathcal{O}(2)$\,~MeV the emergence of the free-streaming neutrino era and develop methods to understand speed of the Universe expansion. We subsequently follow the early universe pass through the hot dense electron-positron plasma epoch and we analyze the paramagnetic characteristics of the electron-positron plasma when exposed to an external primordial magnetic field. The high density of positron antimatter persisted into the Big Bang Nucleosynthesis era which thus requires study of nuclear reactions in the presence of a highly mobile plasma phase, a topic of the following lecture by Chris.

Plasmonics and fusion

22 Particle Simulation of Various Gold Nanoantennas in Laser Irradiated Matter for Fusion Production

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 the response of gold-doped materials to short, intense bursts of infrared radiation, with a focus on the ejection dynamics of electrons from nanoantennas of different shapes.
Our analysis involves calculating and examining various properties, such as momentum and energy, of the resulting charges. Specifically, we compare the energies of ionization products under different doping scenarios to identify conditions that produce ions with the highest energy and momentum after a radiation pulse. Virtual experiments are conducted to investigate the effects of nanoantenna dopants with crossed and circular shapes, varying in size.
We track the dynamics of the interaction between the laser radiation and the doped matter, monitoring ionization products and their energies, as well as field intensities around resonating dopants.
These findings are pivotal for future fusion research, especially in the context of high energy short laser ignition pulses within the NAPLIFE project.

24 Particle acceleration and fusion reactions driven by ultrafast laser pulses

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 effect of metal nanoparticles to the yield and energy of the ions and fusion products, too. The plasmonic near field enhancement can locally increase the efficiency of accelerating processes. We test more target geometries with a 30 mJ/40 fs Ti:Sa laser system.

26 Comparative Analysis of Optical Absorption and Resonating Dynamics of Nanoantenna Dopes at Intense Laser Shots

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 shapes act as resonant nanoantennas. We analyze the absorption characteristics of the medium and calculate ionization product energies for protons, electrons, and ions. Comparative analysis identifies optimal conditions for energy absorption and ion enhancement with nanoparticles of different shapes and sizes, including quadrupole, dipole, and spherical forms.
Additionally, we examine ionization dynamics with quadrupole nanoantennas and address energy absorption saturation.
