Numerical generation of snapshots for fermionic quantum gas microscopy — •Stephan Humeniuk1 and Yuan Wan1,21Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China — 2University of Chinese Academy of Sciences, Beijing 100049, China

Fermionic quantum gas microscope experiments with single-site single-atom resolution have enabled the detection of snapshots of the many-body wavefunction in occupation number space, which has opened the way for analysis techniques that go beyong standard correlation functions. Employing a nested, direct sampling approach for fermion pseudo density matrices as they arise naturally in determinantal quantum Monte Carlo simulations, a stream of Fock space configurations on large systems can be generated numerically. This approach is useful for carefully benchmarking and emulating equilibrium quantum gas microscope experiments.
