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.…
Non-equilibrium coupling to a diffusing density breaks Ising universality
Mattia Scandolo, Johannes Pausch, Michael E. Cates +1
The Ising universality class is remarkably robust to non-equilibrium perturbations, which generically flow to zero under renormalization. We show that this robustness fails when an…
Wetting and Pattern Formation in Non-Reciprocal Ternary Phase Separation
Xiao Ma, Michael E. Cates
Non-reciprocal interactions are among the simplest mechanisms that drive a physical system out of thermal equilibrium, leading to novel phenomena such as oscillatory pattern format…
What exactly is 'active matter'?
Michael te Vrugt, Benno Liebchen, Michael E. Cates
As the study of active matter has developed into one of the most rapidly growing subfields of condensed matter physics, more and more kinds of physical systems have been included i…
Hyperuniformity at the Absorbing State Transition: Perturbative RG for Random Organization
Xiao Ma, Johannes Pausch, Gunnar Pruessner +1
Hyperuniformity, where the static structure factor obeys with , emerges at criticality in systems having multiple, symmetry-unrelated, absorbing states. Impo…
