    "abstract": "We formulate a general multi-mode Gaussian operator basis for fermions, to\nenable a positive phase-space representation of correlated Fermi states. The\nGaussian basis extends existing bosonic phase-space methods to Fermi systems\nand thus enables first-principles dynamical or equilibrium calculations in\nquantum many-body Fermi systems. We prove the completeness and positivity of\nthe basis, and derive differential forms for products with one- and two-body\noperators. Because the basis satisfies fermionic superselection rules, the\nresulting phase space involves only c-numbers, without requiring anti-commuting\nGrassmann variables.",
