Jacobus Verbaarschot is a theoretical physicist interested in nonperturbative effects in Quantum Mechanics and Quantum Field Theory such as correlations of quantum spectra, classical solutions of nonlinear field theories, the spontaneous breaking of chiral symmetry, QCD at nonzero baryon density. He has been particularly fascinated by the interplay between chaos and symmetry in quantum systems. He has studied this problem both in simple systems with only two degrees of freedom and strongly interacting field theories with infinitely many degrees of freedom. The unifying feature in these studies has been the description of eigenvalue correlations in terms of Random Matrix Theory. He believes that a full understanding of a problem in mathematical physics requires a synergy between analytical and numerical methods which is reflected in many of his over 100 research articles. A significant fraction of his publications has been devoted to analysis of mathematical problems in Random Matrix Theory. He has summarized his work in several review articles and lecture notes.
