Large Deviation Functions for Open Quantum Systems with a Strong Symmetry
Fei Liu, Jiayi Gu, Hailong Wang +1
In open quantum systems with strong symmetries, the global scaled cumulant generating function (SCGF) is generally nonanalytic, so the Gärtner-Ellis theorem cannot directly yield…

Computing Large Deviations of First-Passage-Time Statistics in Open Quantum Systems: Two Methods
Fei Liu, Jiayin Gu
We propose two methods for computing the large deviations of the first-passage-time statistics in general open quantum systems. The first method determines the region of convergenc…
