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…
Decoding cell signaling via optimal transport and information theory
Mintu Nandi, Sosuke Ito
Cellular signal processing performs reliably despite molecular noise. Mutual information (MI) is widely used to quantify signaling fidelity, capturing how well outputs discriminate…
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…
Information-Geometric Signatures of Nonconservative Driving
Andrea Auconi, Sosuke Ito
We propose an information-geometric signature of nonconservative driving that detects violations of detailed balance using the Kullback--Leibler divergence and the Fisher informati…
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…
Random Coarse-Graining with Applications to Measuring Irreversibility
Ruicheng Bao, Naruo Ohga, Sosuke Ito
Thermodynamic irreversibility is a fundamental concept in statistical physics, yet its experimental measurement remains challenging, especially for complex systems. At the same tim…
