Oscillatory-nonnormal decomposition of dissipation in Ornstein-Uhlenbeck processes
Ryuna Nagayama, Artemy Kolchinsky, Sosuke Ito
We provide a decomposition of the steady-state entropy production rate associated with an Ornstein-Uhlenbeck process into two contributions: one associated with oscillatory behavio…
Elementary derivation of the dissipation-coherence bound for stochastic oscillators
Artemy Kolchinsky
The dissipation-coherence bound is a conjectured tradeoff between entropy production and the quality of stochastic oscillations. We show that this bound can be derived by combining…
Cycle affinity and winding localize eigenvalues of Markov generators
Artemy Kolchinsky, Naruo Ohga, Sosuke Ito
The complex eigenvalues of Markov generators govern oscillatory properties of relaxation, autocorrelation, and linear response. We show that these eigenvalues are localized by none…
Wasserstein-2 gradient flows and the geometry of entropy production in classical and quantum stochastic thermodynamics
Olga Movilla Miangolarra, Ralph Sabbagh, Artemy Kolchinsky
The second law does more than set the direction of thermodynamic evolution: it endows nonequilibrium transformations with an underlying geometry. In this work, we provide a unified…
Quo vadis, stochastic thermodynamics?
Jan Korbel, Artemy Kolchinsky, Sarah A. M. Loos +4
Stochastic thermodynamics is a framework for describing non-equilibrium processes at the level of fluctuating trajectories, where the state of a system evolves as a stochastic time…
Inferring entropy production in many-body systems using nonequilibrium maximum entropy
Miguel Aguilera, Sosuke Ito, Artemy Kolchinsky
We propose a method for inferring entropy production (EP) in high-dimensional stochastic systems, including many-body systems and non-Markovian systems with long memory. Standard t…
