Thermodynamics and Holographic RG Flow in 3D C-metric
Shaohua Xue, Yingyu Yang, Li-Xin Li
In this paper, we investigate the microscopic derivation of the entropy and the holographic RG flow in 3D C-metric. We first discuss the case of a sector in BTZ (Banados-Teitelboim…
Half-wormholes in a complex SYK model
Yingyu Yang
We compute the half-wormhole contribution in a complex SYK model with one time point. When the chemical potential is zero, the result is similar to two decoupled Majorana SYK model…
The foundations of statistical physics: entropy, irreversibility, and inference
Jonathan Asher Pachter, Ying-Jen Yang, Ken A. Dill
Statistical physics aims to describe properties of macroscale systems in terms of distributions of their microscale agents. Its central tool is the maximization of entropy, a varia…
Statistical Uncertainty Principle in Stochastic Dynamics
Ying-Jen Yang, Hong Qian
Maximum entropy principle identifies forces conjugated to observables and the thermodynamic relations between them, independent upon their underlying mechanistic details. For data…
Duality Symmetry, Two Entropy Functions, and an Eigenvalue Problem in Gibbs' Theory
Jeffrey Commons, Ying-Jen Yang, Hong Qian
We generalize the convex duality symmetry in Gibbs' statistical ensemble formulation, between Massieu's free entropy and the Gibbs entropy as a function…
Nonequilibrium Stationary Process and Fluctuation-Dissipation Relations
Ying-Jen Yang, Hong Qian
A stochastic dynamics has a natural decomposition into a drift capturing mean rate of change and a martingale increment capturing randomness. They are two statistically uncorrelate…
Potentials of Continuous Markov Process and Random Perturbations
Ying-Jen Yang, Yu-Chen Cheng
With a scalar potential and a bivector potential, the vector field associated with the drift of a diffusion is decomposed into a generalized gradient field, a field perpendicular t…
Bivectorial Nonequilibrium Thermodynamics: Cycle Affinity, Vorticity Potential, and Onsager's Principle
Ying-Jen Yang, Hong Qian
We generalize an idea in the works of Landauer and Bennett on computations, and Hill's in chemical kinetics, to emphasize the importance of kinetic cycles in mesoscopic nonequilibr…
Unified formalism for entropy productions and fluctuation relations
Ying-Jen Yang, Hong Qian
Stochastic entropy production, which quantifies the difference between the probabilities of trajectories of a stochastic dynamics and its time reversals, has a central role in none…
The optimal system, similarity reduction and group-invariant solutions to the Fractional Porous Medium equation and Fractional Dual Porous Medium equation
Ying Yang, Li-zhen Wang
In this paper, we developed the group analysis to the time Fractional Porous Medium Equation (FPME) and the time Fractional Dual Porous Medium Equation (FDPME). The symmetry groups…
