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 t…
Quantum Coherence as a Thermodynamic Resource Beyond the Classical Uncertainty Bound
Shanhe Su, Cong Fu, Ousi Pan +3
Thermodynamic uncertainty relations (TURs) establish a fundamental trade-off between current precision and entropy production in nonequilibrium systems, yet the role of genuine qua…
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…
