Date & Time


Auxiliary-Field Quantum Monte Carlo Computation Workshop

The workshop aims to establish a core community of AFQMC practitioners and to advance the development of the AFQMC codes needed for ab initio simulations of real materials by presenting and discussing the latest algorithmic advances from condensed matter physics, quantum chemistry, and ultracold atoms, and linking these to specific plans for code and library development. We hope the workshop will lead to roadmaps for the development of AFQMC and its integration with activities at the CCQ.
