Dr. Yoram Alhassid

Biography

Yoram Alhassid is a theoretical physicist known for his studies on correlated quantum many-body systems and finite-size effects. His research spans nuclear physics, mesoscopic physics, and cold atom physics. A primary focus of Alhassid's work is addressing the significant challenge of deriving the microscopic nuclear properties that underlie effective interactions. This understanding is critical for interpreting astrophysical processes such as nucleosynthesis in supernovas and is essential for the analysis of results expected from new radioactive beam facilities. Alhassid employs configuration-interaction (CI) shell models for microscopic studies, though the combinatorial growth of the many-particle space presents challenges, particularly in mid-mass heavy nuclei. His group is actively developing sophisticated quantum Monte Carlo methods to calculate nuclear properties in model spaces that are orders of magnitude larger than those treated by conventional methods. The group has made notable advancements, including the development of an auxiliary-field Monte Carlo approach which allows for precise calculations of nuclear level density, a key statistical property.
