Abstract

Quantum many-body systems are at the heart of various research fields, including nuclear, atomic, and condensed-matter physics. Fascinated by the beauty and elegance of universal features common to very different and complex many-body systems, I focus on studying universality and on utilizing it for developing predictive tools for the many-body system. Specifically, I will present a theory for describing short-range physics in such systems. To demonstrate its validity, I will consider nuclear systems, and show how it provides a comprehensive picture of short-range correlations and captures quantitatively the impact of short-range correlated pairs on different quantities. I will then focus on recent efforts to construct a systematic framework for the description of short-range physics, extending the relevance and applicability of the theory and opening the path for description of different properties of quantum many-body systems. I will discuss the connection to major experimental efforts in nuclear physics and beyond, studies of physics beyond the Standard Model, neutrino-oscillation studies, and relevance to different subfields of physics. If time permits, I will also share my work on quantum computing and plans for the future, with the goal of providing an accurate description of dynamics in quantum many-body systems.
