Dr. Carl Lehmann

Carl is a Postdoctoral Researcher at the University of Würzburg. His main scientific interests are strongly correlated electron systems, with a particular focus on the emergence and physical consequences of Green’s-function zeros and non-Hermitian topology in Green’s functions. He combines analytical techniques, including quantum field theory, with numerical approaches such as nonequilibrium Green’s-function methods, density-matrix renormalization group (DMRG), and exact diagonalization.
