Universality, short-range physics, and quantum computing for the quantum many-body problem

Abstract

Quantum many-body systems are at the heart of various research fields, including nuclear, atomic, and condensedmatter 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 manybody 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, studies of physics beyond the Standard Model, 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
