Large Deviation Functions of Open Quantum Systems with Strong Symmetries
Fei Liu, Jiayi Gu, Hailong Wang +1
In open quantum systems with strong symmetries, the global rate function is typically non-convex and thus cannot be directly computed from the global scaled cumulant generating fun…
Balancing Power, Efficiency, and Constancy under Broken Time-Reversal Symmetry
