Dataset corresponding to "Observation of Strong-to-Weak Spontaneous Symmetry Breaking in a Dephased Fermi Gas"

The provided files implement the numerical and data-analysis procedures used to extract the quantities presented in the manuscript from single-site-resolved experimental snapshots and from the corresponding machine-learned Gaussian states. The code includes routines for learning fermionic Gaussian states from experimental data and for evaluating the different correlation functions discussed in the publication.

In particular, it provides the analysis used to calculate Rényi-1 and Rényi-2 correlators and the corresponding condensate densities. The implementation includes the quantum–quantum (QQ), quantum–classical (QC), and classical–classical (CC) estimators used in the manuscript. For the Rényi-2 quantities, the analysis evaluates coincidences between pairs of experimental configurations as well as pairs of configurations related by the displacement of a particle.
