Correlated quantum lattice models and their computational solutions constitute an important research direction in contemporary condensed matter physics. In this talk, I will present few examples of such models motivated from field theoretical analysis and their solutions by employing state-of-the-art numerical tools, ranging from quantum Monte Carlo, tensor renormalization group, stochastic analytical continuation, etc. Such joint efforts have proved to greatly help us to understand few fundamental questions in non-Fermi-liquid, frustrated magnets, twisted bilayer graphene and topological state of matter. I will try to convey the message that through the fruitful dialogue between theoretical and numerical communities, a bridge connecting together theory, numerical and experimental studies of correlated electron systems can be built.
