Event description: 

Based on the recent conceptual and technical developments of quantum Monte Carlo simulations in correlated electron systems, I will present and discuss fresh results of itinerant quantum critical points, i.e., the critical phenomena arising from the strong coupling between Fermi surface and bosonic fluctuations, which are made possible by the self-learning Monte Carlo scheme. After which, I will also discuss the lately proposed duality relations between interaction-driven topological phase transitions and deconfined quantum critical points, which is verified via unbiased large-scale quantum Monte Carlo simulations.
