Temporal Coarse-Graining as the Origin of Macroscopic Friction in Quantum Spin Chains via Data-Driven Liouvillian Extraction
The episode discusses a paper using data-driven methods to show that macroscopic friction and viscosity emerge from temporal coarse-graining in quantum spin chains. Hosts explain how this emergence is tied to the causal direction of inference and how restricting observable dictionaries affects the resulting model's dissipation properties.
