●    Lattice QCD: Utilizing large-scale numerical simulations to calculate fundamental properties of quarks and gluons.
●    Quantum Computation: Exploring how quantum computation might accelerate the calculations in quantum field theories and nuclear many-body problems.
●    Relativistic Heavy-Ion Collisions: Studying the Quark-Gluon Plasma (QGP), chiral effects, and transport phenomena in extreme conditions.
●    Nuclear Astrophysics: Investigating nucleosynthesis, neutrino-matter interactions, and the physics of compact objects like neutron stars.
●    High-Energy Neutrinos and Cosmic Rays: Modeling atmospheric and astrophysical particle fluxes and their interactions.
●    Nuclear and Atomic Theory for Fundamental Symmetries, Low-Energy Neutrinos, and Dark Matter Physics: Applying nuclear and atomic many-body theories to searches of physics beyond the Standard Model, including precision tests in nuclear beta decay, atomic parity and time-reversal violations, direct detection of low energy neutrinos and dark matter candidates.
●    Effective Field Theory (EFT): Developing systematic frameworks for nuclear forces, electroweak processes, and perturbative QCD.

V. Expected achievements:
In the coming years, the Theoretical Nuclear Physics thematic group expects to make significant contributions to our understanding of matter at its most fundamental level. Our core members will utilize Lattice QCD and Effective Field Theories to provide precision predictions for hadron structures and electroweak matrix elements, which are vital for interpreting experiments at global facilities like the Electron-Ion Collider (EIC).
In the regime of high-energy density, our group will continue to lead research in Relativistic Heavy-Ion Collisions, specifically focusing on the spin-polarization effects and chiral transport phenomena that characterize the strongest magnetic fields in the universe. Simultaneously, we aim to bridge the gap between nuclear physics and Astrophysics by exploring how neutrino physics and nuclear equations of state govern the evolution of supernovae and the merger of neutron stars.
The group will also play a pivotal role in the multi-messenger era, improving models for high-energy cosmic rays and neutrinos to better understand the results from observatories like IceCube. Furthermore, by calculating nuclear responses with high precision, we will provide the theoretical foundation necessary for dark matter direct detection and other low-energy tests of fundamental symmetries. Through these diverse yet interconnected efforts, the TG members will solidify Taiwan’s position as a key hub for nuclear theory, fostering close collaborations between local researchers and the international experimental community.
