### Event details

At nonzero quark chemical potential lattice QCD simulations are severely hindered by the sign problem, which arises when the fermion determinant becomes complex. As the spectral properties of the Dirac operator are described by random matrix theory, the latter can be used to improve our understanding of the sign problem. In this talk I will discuss the correspondence between QCD and RMT in the presence of a chemical potential and will present a novel solution to the sign problem in dynamical simulations of random matrices.
