Zakopane 2026 Conference on Nuclear Physics

Many-body Green's function theory stands out among microscopic theories for its capability to encapsulate infromation on ground state properties, response and single particle spectroscopy within the same framework. Different aspects of the many-body correlations and dynamics of a given nucleus can then be investigated simultaneously with the same microscopic approach.

The first part of the...

A major goal of nuclear theory is to explain the structure and properties of atomic nuclei in an ab initio approach starting from nuclear forces fixed in free-space scattering. Apart from the two nucleon forces, the three-body forces are also important in describing systems from light nuclei to nuclear matter. However, an accurate and simultaneous ab initio prediction for both light nuclei and...

The optical potential is a well-established and widely used tool to describe nucleon-nucleus scattering processes. Within this approach, it is possible to compute the scattering observables for elastic processes across a wide region of the nuclear landscape and extend its usage to inelastic scattering and other types of reactions.

Since phenomenological approaches lack predictive power, we...

Atomic nuclei are ideal probes to test fundamental symmetries. For instance, nuclei are used as targets to detect dark matter particles, and electric dipole moments of nuclei can help to unveil why there is more matter than antimatter in the universe.

Nuclear $\beta\beta$ decays also play a paramount role. If no neutrinos happen to be emitted in the decay, this would immediately imply that...

The nuclear shell structure serves as the backbone for exploring the complex nuclear structure that emerges from nucleon-nucleon interactions. In recent years, it has become the forefront for both experimental and theoretical research in nuclear physics. Recent studies indicate that the shell structure is altered by the extreme proton-to-neutron number ratio in neutron-rich exotic nuclei, a...

Recent experiments have shown that fission fragments carry intrinsic angular momentum with essentially no correlation between fragments, motivating new theoretical studies. Different microscopic models will be discussed to understand the generation of fragment spin in fission. These approaches, based on time-dependent density functional theory and a time-dependent collective Hamiltonian,...

Nuclear energy density functional (EDF) theory provides a unified framework for describing both static and dynamical properties of nuclei and extended nuclear matter. In particular, its time-dependent extension enables microscopic studies of non-equilibrium phenomena in strongly paired systems, such as those expected in the inner crust of neutron stars, where nuclei coexist with a superfluid...

The synthesis of superheavy elements is a major foundational scientific problem of joint interest to both the fields of physics and chemistry. Experimentally, fusion-evaporation reactions are commonly employed for the synthesis of superheavy nuclei, but thus far have only resulted in neutron-deficient superheavy nuclei.
The pursuit of the "island of stability" for superheavy nuclei thus...

Most current neutron star EoS inferences are intentionally agnostic: they reconstruct the cold beta-equilibrated pressure-density relation without committing to a microscopic composition. This is appropriate for masses, radii, and tidal deformabilities. Still, it leaves out quantities that depend on the off-equilibrium energy functional, such as composition, frozen sound speeds, direct-Urca...

Time-dependent density functional theory (TDDFT) provides a fundamental framework for describing nuclear collective time-dependent processes, ranging from small-amplitude collective oscillations to large-amplitude phenomena such as fission and heavy-ion reactions. However, due to its mean-field nature, TDDFT accounts only for one-body dissipation effects and fails to describe the spreading...

Atomic nuclei are complex many-body systems with a number of constituents ranging from very few to several hundred [1-2]. Among the difficult aspects, nuclei are self-bound systems that require treating a continuum of wave functions in Hilbert space. The nuclear strong interaction is poorly understood and highly non-perturbative, with the onset of multi-body interactions beyond the usual...

Quantum computing offers a fundamentally new paradigm for simulating the real-time dynamics of quantum many-body systems, overcoming the exponential scaling limitations of classical approaches. By encoding quantum states directly into qubits and leveraging entanglement as a computational resource, quantum algorithms can efficiently capture the complex correlations that govern nuclear...

An accurate description of many-body dynamics in nuclear physics is a major challenge for classical simulation techniques. Hamiltonian simulation on digital quantum computers offer the possibility of reducing the computational cost when tackling these problems. In this talk, I will discuss recent advances in the simulation of both nuclear and neutrino systems using quantum computers and show...

Nuclear many-body calculations on classical computers typically involve Monte Carlo simulations. These suffer from the fermionic sign problem where the signal-to-noise ratio diminishes as the system size grows. Moreover, these simulations are performed in Euclidean which complicates calculations of real-time dynamics from such simulations. Quantum computation avoids these issues by unitary...

Quantum computers have the potential to efficiently tackle problems that grow exponentially in complexity on classical computers. In the context of simulating physical systems, they may help reduce the problems related to the rapid expansion of Hilbert space with increasing particle number and handle highly entangled states more effectively.

In this contribution, we explore prospects for...

The dynamics of quantum many-body systems underpin some of the most compelling open questions in low-energy nuclear physics. From the microscopic mechanisms driving fusion to the large-amplitude collective motion governing fission, these processes span a remarkable range of complexity. Understanding them, especially at the limits of nuclear stability, requires models that capture continuum...
