Inferring Microscopic Explanatory Structures from Observational Constraints via Large Deviations
Akihisa Ichiki
We study how macroscopic observational constraints restrict admissible microscopic explanatory structures when no intrinsic order or dynamics is assumed a priori. Starting from an…
Relativity of Observation: Operational Intensive Variables in Nonequilibrium Thermodynamics
Akihisa Ichiki
We formulate nonequilibrium thermodynamics in which intensive variables acquire operational meaning through measurement protocols consistent with local reciprocity. Using physical…
Stochastic dynamics without detailed balance condition connecting simple gradient method and Hamiltonian Monte Carlo
Akihisa Ichiki, Masayuki Ohzeki
Sampling occupies an important position in theories of various scientific fields, and Markov chain Monte Carlo (MCMC) provides the most common technique of sampling. In the progres…
Mathematical understanding of detailed balance condition violation and its application to Langevin dynamics
M. Ohzeki, A. Ichiki
We develop an efficient sampling method by simulating Langevin dynamics with an artificial force rather than a natural force by using the gradient of the potential energy. The stan…
Full-order fluctuation-dissipation relation for a class of non-equilibrium steady states
Akihisa Ichiki, Masayuki Ohzeki
Acceleration of relaxation toward a fixed stationary distribution via violation of detailed balance was reported in the context of a Markov chain Monte Carlo method recently. Inspi…
Langevin dynamics neglecting detailed balance condition
Masayuki Ohzeki, Akihisa Ichiki
An improved method for driving a system into a desired distribution, for example, the Gibbs-Boltzmann distribution, is proposed, which makes use of an artificial relaxation process…
