My paper "Statistical decision theory in thermodynamics" is now on arXiv. arxiv.org/abs/2610.26617

Statistical decision theory in thermodynamics

We introduce statistical decision theory in stochastic thermodynamic systems. Statistical decision theory integrates several statistical tasks, such as estimation, hypothesis testing, and...

Anisotropic information geometry of entropy production

We reveal that the information geometry of entropy production exhibits an intrinsic anisotropy, providing a unified origin for the inequivalent geometric constraints obeyed by its different...

Trade-off Relation for Black Hole Entropy Fluctuations

Black holes respond to infalling quantum matter fields by changing their entropy. Since such matter is quantum in nature, the entropy response should be sensitive to its quantum fluctuations. We...
