Emergent causal order and time direction: bridging causal models and tensor networks
Carla Ferradini, Giulia Mazzola, V. Vilasini
Can the direction of time and the causal structure of space-time be inferred from operational principles? Causal models and tensor networks offer complementary perspectives: the fo…

Cyclic functional causal models beyond unique solvability with a graph separation theorem
Carla Ferradini, Victor Gitton, V. Vilasini
Functional causal models (fCMs) specify functional dependencies between random variables associated to the vertices of a graph. In directed acyclic graphs (DAGs), fCMs are well-und…

Cyclic quantum causal modelling with a graph separation theorem
Carla Ferradini, Victor Gitton, V. Vilasini
Causal modelling frameworks link observable correlations to causal explanations, which is a crucial aspect of science. These models represent causal relationships through directed…
