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…
Interplay between Standard Quantum Detailed Balance and Thermodynamically Consistent Entropy Production
Xin-Hai Tong, Kohei Yoshimura, Tan Van Vu +1
We demonstrate that, for a quantum Markovian semigroup on a finite-dimensional Hilbert space, if it satisfies the standard quantum detailed balance condition, its generator admits…
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…
Improving Variational Counterdiabatic Driving with Weighted Actions and Computer Algebra
Naruo Ohga, Takuya Hatomura
Variational counterdiabatic (CD) driving is a disciplined and widely used method to robustly control quantum many-body systems by mimicking adiabatic processes with high fidelity a…
Characteristic oscillations in frequency-resolved heat dissipation of linear time-delayed Langevin systems: Approach from the violation of the fluctuation-response relation
Xin Wang, Ruicheng Bao, Naruo Ohga
Time-delayed effects are widely present in nature, often accompanied by distinctive nonequilibrium features, such as negative apparent heat dissipation. To elucidate detailed struc…
Microscopic theory of Mpemba effects and a no-Mpemba theorem for monotone many-body systems
Naruo Ohga, Hisao Hayakawa, Sosuke Ito
Mpemba effects (MPEs), where a hotter system cools faster than a colder one, present intriguing anomalies in relaxation processes. Despite their universal observation and significa…
Thermodynamic bounds on spectral perturbations, with applications to oscillations and relaxation dynamics
Artemy Kolchinsky, Naruo Ohga, Sosuke Ito
In discrete-state Markovian systems, many important properties of correlations functions and relaxation dynamics depend on the spectrum of the rate matrix. Here we demonstrate the…
Thermodynamic Bound on the Asymmetry of Cross-Correlations
Naruo Ohga, Sosuke Ito, Artemy Kolchinsky
The principle of microscopic reversibility says that, in equilibrium, two-time cross-correlations are symmetric under the exchange of observables. Thus, the asymmetry of cross-corr…
Information-geometric structure for chemical thermodynamics: An explicit construction of dual affine coordinates
Naruo Ohga, Sosuke Ito
We construct an information-geometric structure for chemical thermodynamics, applicable to a wide range of chemical reaction systems including non-ideal and open systems. For this…
Inferring nonequilibrium thermodynamics from tilted equilibrium using information-geometric Legendre transform
Naruo Ohga, Sosuke Ito
Nonstationary thermodynamic quantities depend on the full details of nonstationary probability distributions, making them difficult to measure directly in experiments and numerics.…
