"In this thesis we study strongly correlated quantum systems in extreme temperature and\r\ndensity conditions. A prominent example is the quark-gluon plasma produced in ultra-\r\nrelativistic heavy-ion collisions. Since the degrees of freedom in the systems of interest are\r\nstrongly coupled the use of non-perturbative methods is required. Our working method\r\nis lattice field theory allowing for high precision ab-initio calculations of physical quan-\r\ntities based on Monte Carlo simulations. We study QCD-like theories at finite density.\r\nThis introduces the sign problem to the lattice preventing the applicability of importance\r\nsampling algorithms. Promising methods to tackle the sign problem are the Complex\r\nLangevin evolution on the one hand and Lefschetz Thimbles on the other hand. In this\r\nwork we propose novel algorithmic ideas to both approaches which are put to work in\r\nsimple models with a sign problem as well as in lattice gauge theories. Moreover, we in-\r\nvestigate real-time properties of quantum systems at finite temperature which is necessary\r\nfor the computation of transport coefficients. To that end we conduct lattice simulations\r\nin imaginary time which are aimed at improving the spectral reconstruction of thermal\r\nfeatures. Moreover, we study simulations directly in real-time by means of the Complex\r\nLangevin evolution equipped with variable transformations."^^ . "2019" . . . . . . . "Felix Paul Gerhard"^^ .
