pre-print
Zombie States are a recently introduced formalism to describe coupled coherent Fermionic states which address the Fermionic sign problem in a computationally tractable manner. Previously it has been shown that Zombie States with fractional occupations of spin-orbitals obeyed the correct Fermionic creation and annihilation algebra and presented results for real-time evolution [Dmitrii V. Shalashilin, J. Chem. Phys. 148, 194109 (2018)]. In this work we extend and build on this formalism by
