Jakša Vučičević is Associate Research professor at the Institute of Physics Belgrade, Serbia. He received his PhD in condensed matter physics from the University of Belgrade in 2015, under supervision of Dr Darko Tanasković. In the two-year period 2015-2017, he was a postdoc in the ERC funded group of Dr Olivier Parcollet at IPhT, CEA Saclay in France. Dr Vučičević focuses on the theory of strongly correlated electrons, which is relevant for a large class of materials, including cuprate superconductors and kappa-organic systems. During his PhD studies, he contributed to the understanding of quantum critical phenomena associated with the Mott metal-insulator transition. Since his postdoc years, Dr Vučičević specializes in the development of numerical methods for the quantum many-body solution of interacting lattice models. Most recently, he was involved in a breakthrough discovery of the analytical solution of temporal integrals in Feynman diagrams, which solves a long-standing problem in the computation of dynamic response functions in interacting quantum systems at finite temperature. Since January 2023, he is the PI of the ERC Starting Grant SCLoTHiFi. The project aims to apply the newly developed real-frequency diagrammatic Monte Carlo method to the computation of spectral and transport properties of the two-dimensional Hubbard model and its generalizations, and this way shed light on the physical mechanisms that determine the normal phase resistivity and the superconducting critical temperature in the cuprates and other related systems.
