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…

Semi-Markov Processes in Open Quantum Systems. III. Large Deviations of First Passage Time Statistics
Fei Liu, Shihao Xia, Shanhe Su
In a specific class of open quantum systems with finite and fixed numbers of collapsed quantum states, the semi-Markov process method is used to calculate the large deviations of t…
