Abstract
 

In this talk, I will present recent developments in conceptual and technical aspects of numerical simulations in correlated electron systems, in particular in the new quantum Monte Carlo methods. Fresh results on itinerant quantum critical points, i.e. the critical phenomena arising from the strong coupling between Fermi surface and bosonic fluctuations will be discussed, as well as the recently discovered, fundamental duality relations between interaction-driven topological phase transitions and deconfined quantum critical points. For the latter, not only its static but also dynamical properties, are revealed via unbiased large-scale numerical efforts. In the end, I will point out promising future directions in combining numerical methods and quantum field theory in the era of big-data and artificial intelligence in pursuing the understanding of correlated electron systems.
