Thermodynamic Uncertainty Relation Violations in Quantum Collisional Models
How the thermodynamic uncertainty relation — a trade-off bounding a current's precision by the entropy it dissipates — can be violated when open-system dynamics are modeled as a driven spin interacting through discrete collisions with a stream of auxiliaries. Learners study how the Markovian (Lindblad) limit and two kinds of non-Markovian memory (longer collisions, interacting auxiliaries) give rise to steady-state versus necessarily-transient violation regimes, while the stricter quantum TUR bound remains intact.
