The dynamics of critical fluctuations in asymmetric Curie-Weiss models

open access: yes, 2017
We study the dynamics of fluctuations at the critical point for two time-asymmetric version of the Curie-Weiss model for spin systems that, in the macroscopic limit, undergo a Hopf bifurcation.

Quaternionic differential operators

open access: yes, 2001
Motivated by a quaternionic formulation of quantum mechanics, we discuss quaternionic and complex linear differential equations. We touch only a few aspects of the mathematical theory, namely the resolution of the second order differential equations with

Magnetoelectric ordering of BiFeO3 from the perspective of crystal chemistry

open access: yes, 2011
In this paper we examine the role of crystal chemistry factors in creating conditions for formation of magnetoelectric ordering in BiFeO3. It is generally accepted that the main reason of the ferroelectric distortion in BiFeO3 is concerned with a ...

Crossing conditions in coupled cluster theory [PDF]

open access: yes, 2017
We derive the crossing conditions at conical intersections between electronic states in coupled cluster theory, and show that if the coupled cluster Jacobian matrix is nondefective, two (three) independent conditions are correctly placed on the nuclear ...

Evaluating the accuracy of the EcoservR toolkit for fine‐resolution habitat mapping

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Accurate habitat maps are essential for monitoring ecological change and supporting nature recovery planning. We evaluate the EcoservR rule‐based habitat mapping toolkit using field survey data from Merseyside and the North York Moors, validating classifications across the Joint Nature Conservation Committee (JNCC) Phase 1 hierarchy.
