Dynamics and Structure of Molten Neodymium Titanate
Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.ABSTRACT Binary rare earth titanates can be vitrified using levitation melt quenching, and their glasses are promising for optical applications. To better understand their thermophysical properties and dynamics, we have used molecular dynamics (MD) and empirical potential structure refinement (EPSR) to simulate molten neodymium titanate, 83TiO2–17Nd2O3.

Equilibrium and Nonequilibrium Viscosity of PbSiO3 Glass: Viscous Flow and Structural Relaxation
Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.ABSTRACT Viscosity measurements above ∼1012 Pa·s are intrinsically time dependent, and thus equilibrium values can only be defined after structural relaxation is completed. This work investigates the evolution of nonequilibrium viscosity in PbSiO3 glass below the glass transition region and its approach to equilibrium viscosity during structural ...

The Well-Posedness and Ergodicity of a CIR Equation Driven by Pure Jump Noise
MathematicsThe current paper is devoted to the dynamical property of the stochastic Cox–Ingersoll–Ross (CIR) model with pure jump noise, which is an extension of the CIR model.

Knowledge as a Breaking of Ergodicity
Neural ComputationAbstract We construct a thermodynamic potential that can guide training of a generative model defined on a set of binary degrees of freedom. We argue that upon reduction in description, so as to make the generative model computationally manageable, the potential develops multiple minima.

Generalized free wreath products and their operator algebras
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract We develop a new approach on free wreath products, generalizing the constructions of Bichon and of Fima‐Pittau. We show stability properties for certain approximation properties such as exactness, Haagerup property, hyperlinearity, and K‐amenability. We study qualitative properties of the associated von Neumann algebra: factoriality, primeness,

Towards the boundary of the fine curve graph
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract The fine curve graph was introduced as a geometric tool to study homeomorphisms of surfaces. In this paper, we study the Gromov boundary of this space and the local topology near points associated with certain foliations and laminations. We then give several applications including finding dynamically explicit elements with positive stable ...

Geometric ergodicity and perfect simulation [PDF]
, 2004 This note extends the work of Foss and Tweedie (1998), who showed that availability of the classic Coupling from the Past (CFTP) algorithm of Propp and Wilson (1996) is essentially equivalent to uniform ergodicity for a Markov chain (see also Hobert and ...
