Hierarchical Reconstruction of Time-arrow from Multi-time Correlations
Yijia Cheng, Ruicheng Bao, Zhonghuai Hou
The entropy production rate (EPR), a key measure of thermodynamic irreversibility in stochastic thermodynamics, is difficult to determine directly in experiments, motivating lower-…

Universal trade-off between irreversibility and intrinsic timescale in thermal relaxation with applications to thermodynamic inference
Ruicheng Bao, Chaoqun Du, Zhiyu Cao +1
We establish a general lower bound for the entropy production rate (EPR) based on the Kullback-Leibler divergence and the Logarithmic-Sobolev constant that characterizes the time-s…

Accelerating Quantum Relaxation via Temporary Reset: A Mpemba-Inspired Approach
Ruicheng Bao, Zhonghuai Hou
Slow relaxation processes spanning widely separated timescales pose fundamental challenges for probing steady-state properties and engineering functional quantum systems, such as q…
