Law of large numbers for certain cylinder flows
, 2012 We construct new examples of cylinder flows, given by skew product extensions of irrational rotations on the circle, that are ergodic and rationally ergodic along a subsequence of iterates. In particular, they exhibit law of large numbers.

Small Methods, EarlyView.A/B‐site co‐doping combined with templated grain growth enables synergistic defect and domain engineering in textured PIN–PMN–PT ceramics. The approach simultaneously enhances piezoelectric response and mechanical quality factor, achieving a balanced soft–hard characteristic.

Equilibration of quantum cat states
SciPost Physics, 2020 We study the equilibration properties of isolated ergodic quantum systems initially prepared in a cat state, i.e a macroscopic quantum superposition of states.

Ergodic sampling of the topological charge using the density of states
European Physical Journal C: Particles and Fields, 2021 In lattice calculations, the approach to the continuum limit is hindered by the severe freezing of the topological charge, which prevents ergodic sampling in configuration space.

An estimation of the logarithmic timescale in an ergodic dynamics
, 2017 An estimation of the logarithmic timescale in quantum systems having an ergodic dynamics in the semiclassical limit of quasiclassical large parameters, is presented.

The importance of considering regimes in long‐term asset allocation to real estate
Real Estate Economics, EarlyView.Abstract We investigate the long‐term, regime‐dependent asset allocation of an investor's wealth in a mixed‐asset portfolio that includes publicly traded real estate. We show that augmenting standard VAR models with Markov‐switching features not only improves predictive power for asset returns but also introduces economically meaningful horizon effects

Optimal harvesting for a stochastic competition system with stage structure and distributed delay
Electronic Journal of Qualitative Theory of Differential Equations, 2021 A stochastic competition system with harvesting and distributed delay is investigated, which is described by stochastic differential equations with distributed delay.

Ergodic Properties of Classical SU(2) Lattice Gauge Theory
, 1999 We investigate the relationship between the Lyapunov exponents of periodic trajectories, the average and fluctuations of Lyapunov exponents of ergodic trajectories, and the ergodic autocorrelation time for the two-dimensional hyperbola billiard.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Generalizability theory (G‐theory) defines a statistical framework for assessing measurement reliability by decomposing observed variance into meaningful components attributable to persons, facets, and error. Classic G‐theory assumes homoscedastic residual variances across measurement conditions, an assumption that is often violated in ...
