Microscopic Dynamical Entropy II: Statistical and Stochastic Thermodynamics of Hamiltonian Systems
Mingnan Ding, Michael E. Cates
The Microscopic Dynamical Entropy (MDE) introduced in Ref. [1] describes irreversible relaxation of selected variables x within a finite closed Hamiltonian system of fixed total en…

Microscopic Dynamical Entropy I: Quantifying Hamiltonian Irreversibility in Large and Small Systems
Mingnan Ding, Michael E. Cates
We introduce a Microscopic Dynamical Entropy (MDE) for Hamiltonian systems, defined with respect to a chosen partition of degrees of freedom into a system X and its environment Y.…

An ideal entropy transporter with finite power and vanishing fluctuation
Mingnan Ding, Jun Wu, Xiangjun Xing
We study a micro-magnet that interacts with a spin-polarized electric current, a heat bath, as well as a static magnetic field. The resulting non-equilibrium steady-state transport…
