Revealing Fermionic Quantum Criticality from New Monte Carlo Techniques — •Zi Yang Meng — Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China

In this talk, I will present recent developments in the numerical investigations of fermionic quantum criticality in the form of Fermi surfaces coupled to various critical bosonic fluctuations. The thence obtain itinerant quantum critical points reveal rich and fundamental physics that has immediate impact on both theoretical and experimental investigations in the correlated electrons systems such as Cu- and Ir-based superconductors, heavy-fermion systems as well as the interacting topological state of matter and phase transitions. These developments are made possible due to the insightful model design as well as the timely algorithmic developments in the Monte Carlo techniques.
