The only way to study the properties of asymmetric nuclear matter at high densities in the laboratory conditions is to investigate the relativistic heavy ion collisions. A complementary source of information are the astrophysical observations and gravitational waves. The degree of compression and pressures achieved during the heavy ion collision depend on the susceptibility of the nuclear...

The study of the density dependence of the equation of state (EOS) of nuclear matter at supra-saturation densities is a major topic of modern nuclear physics, with important implications in many fields. These span from astrophysics, such as the behavior of neutron stars and core collapse supernovae, to heavy ion collision (HIC) phenomena. Symmetry energy can be investigated not only by means...

Streaming readout (SRO) data acquisition is emerging as a key paradigm for high-luminosity nuclear and particle physics experiments, enabling triggerless operation through continuous, time-stamped data streams processed in software. By organizing detector hits into time slices and performing real-time reconstruction and selection using global detector information, SRO enables efficient data...

Microstrip detectors are essential, high-resolution position-sensitive sensors used in nuclear physics for tracking, vertex reconstruction, and beam monitoring. In addition to those detectors pad arrays are used when moderate position resolution is required combined with unambiguity in particle detection, for example in beam monitoring. Different ancillary detectors are based on microstrips...

The region of the nuclear chart corresponding to light radioactive nuclei has, over the years, yielded many surprising results, among others the discovery of the halo structure in neutron and proton dripline nuclei. This region of the nuclear chart is also rich of many other phenomena like the appearance of molecular-like structures where -particle-clusters are bound together by the exchange...

The second $0_{2}^+$ state of $^{12}$C at an excitation energy of 7.654 MeV, known as the Hoyle state [1], is crucial to understanding how $^{12}$C is formed in stellar nucleosynthesis. Despite recent studies, there is no consensus on the properties of the Hoyle state, with different theoretical models predicting a range of radii values and spatial arrangements [2-3].
Experimentally, only a...

Clustering in finite nuclei is best understood not as an isolated peculiarity of a few light systems, but as a structural and dynamical regime whose signatures run from spectroscopy to decay. In this talk, I will discuss how cluster correlations emerge, evolve, and eventually disappear as nuclei are driven across density- and temperature-controlled regimes, including dilution-induced quantum...

It has been shown for several years that cluster states in nuclei could be understood through universal microscopic approaches [1, 2]. Furthermore, starting from a nuclear matter model including clusters, and with a finite nucleus-matter correspondence, it is possible to predict and observe alpha clusters at the surface of Tin isotopes[3]. Here, we present a unified theoretical framework for...

The formation of nuclear clusters, emerging as many-body correlations at sub-saturation densities, constitutes an essential feature for the construction of a reliable Equation of State (EOS). Phenomenological models based on energy density functionals (EDFs) offer a convenient approach to account for these bound states by introducing clusters as additional degrees of freedom (DOF)[1].

The effect of $N/Z$ has been probed through different processes such as reactions around the Fermi energy where nuclear dynamics is prominent. Alternatively, the fusion of two nuclei is a process where both the initial structure of the two nuclei and the collision dynamics can play an important role. Light nuclei in particular provide a rich testing ground for the interplay of nuclear...

These spectrometers deliver intense beams of exotic heavy nuclei, which are used as projectiles in inverse kinematics for fission studies performed with the SOFIA/R3B setup. Building on...

In March 2025, at the GSI laboratory in Germany, the ASY-EOS II experiment was conducted. The reaction ^{197}Au+^{197}Au was studied at beam energies of 280, 400, 600, and 1000 AMeV. The experiment was designed to investigate high-density nuclear matter and to provide a new and robust constraint on the symmetry energy term of the nuclear equation of state (EoS).

The nuclear symmetry energy and its density dependence, particularly above saturation density, remain among the most significant uncertainties in the nuclear equation of state (EoS). These properties play a crucial role in both intermediate-energy heavy-ion collisions and the structure of neutron star matter. Experimental information at supra-saturation densities, however, is still limited,...

Heavy ion collisions provide a unique laboratory for studying nuclear matter under extreme conditions. The mid-rapidity region, characterized by particles emitted perpendicular to the beam axis, shows experimentally a neutron enrichment. The isospin transport processes and the density-dependent behaviour of the symmetry energy affect the transport of nucleons to this region of interaction...

The trace anomaly of dense matter, $\Delta \equiv 1/3 - P/\varepsilon$, defined in terms of the ratio of pressure $P$ to energy density $\varepsilon$, quantifies deviations from conformal symmetry and plays a central role in both the hydrodynamic response and gravitational equilibrium. While $\Delta(\varepsilon)$ has recently been inferred from neutron star observations, we report the first...

Neutrino physics is essential for understanding a wide range of astrophysical phenomena.
