Abstract

In the present paper, a new model of the collision term, of the Boltzmann Kinetic equation dealing with binary gas mixture affected by a centrifugal field, is introduced. The new model is representing a modification of the BGK (Bhatnagar-Gross-Krook) model of the Boltzmann kinetic equation to be suitable for studying the influence of centrifugal field affected on gases mixture. The scientific achievement of the new model is that it is a very simple model without any mathematical complexity; but without any loss of generality. We shed light upon that the new model is satisfied the conservation of energy, conservation of mass, and conservation of momentum laws, the second law of thermodynamic, and the principle of maximum entropy production that is like the BGK model itself. Complete mathematical model for a centrifugal field, used in Uranium enrichment process affected on gases mixture between two coaxial circular porous rotating cylinders, is presented which is an important application for our new model. We also, introduced the complete irreversible thermodynamics properties of the system for the first time at all, for the best of our knowledge. The entropy, entropy flux, entropy production, thermodynamic forces, kinetic coefficients are presented for our model system. The ratios between the different contributions of the internal energy changes are predicted via the extended Gibbs equation. The main important implementation of the model is the uranium enrichment that is used in nuclear energy generation or nuclear weapons, many medical applications and various industrial amazing applications. The flow of a binary gases mixture of UF6, and N2 between rotating cylinders is the first important suggested problem enforcement of the new model.

Universal sampling of spin systems across quenched disorder

Statistical physics extracts macroscopic laws by averaging over the many microscopic degrees of freedom of a system. Disordered systems demand a second and far harder average, one over the quenched randomness itself. The classic analytical routes, the replica and cavity methods, become uncontrolled outside mean-field or tree-like limits, and conventional numerical algorithms like parallel tempering require expensive, independent equilibration for every disorder realization. In this work, we introduce a universal neural variational framework that amortizes inference across the disorder ensemble, eliminating both the need for per-instance Markov chain equilibration and the cost of retraining instance-specific variational ansatzes. Built on an encoder-decoder Transformer architecture, after training once, it produces an explicit approximation to the Boltzmann distribution given previously unseen disorder realizations without further optimization. We validate this framework on 2D Edwards-Anderson models, and apply it to the random-bond Ising model, successfully capturing the Binder cumulant crossings near the Nishimori multicritical point. These results shift the object of variational inference from the single instance to the disorder ensemble, opening a route to frustrated many-body systems where instance-by-instance computation is prohibitive.

Information-Theoretic Characterization of Macroscopic Chaos Emerging from the Chemical Master Equation

Open chemical reaction networks exhibit stochastic concentration dynamics at finite system sizes, whereas their macroscopic limit is governed by deterministic rate equations that can display chaos. In this Letter, we show theoretically that a rate of information loss constructed from two-time mutual information recovers the Kolmogorov-Sinai entropy in the deterministic limit. We verify this result through numerical simulations of a Markov jump process for a three-species system involving seven reactions.

Orientational order on non-orientable domains

We study the statistical properties of passive and active many-body systems with orientational degrees of freedom on non-orientable domains. By rephrasing topological constraints as non-local symmetry relations on an orientable double-cover, we show that non-orientability eliminates global rotational soft modes without acting like an external field. In a passive XY model, this results in topological caging, where orientational fluctuations that exhibit conventional diffusive behavior on a torus saturate on a Klein bottle to a finite value that we compute exactly in the thermodynamic limit. In models of active self-propelled particles with orientational degrees of freedom, topological caging persists despite continuously changing interaction neighborhoods. In an active Ising spin model, non-orientability enforces the coexistence of ordered anti-parallel domains with vanishing global polar order, a state that is absent on orientable domains.
