Nilpotent orbits of sl(n,R) admit no Gibbs state
Jérémie Pierard de Maujouy, Guillaume Neuttiens
Gibbs states are probability distributions defined on Hamiltonian G-manifolds. They are parametrized by an open set of the Lie algebra g and arise as natural equilibrium states wit…
From Whole-Space Theory to Boundary Value Problems for Mixed-Order PDEs
Guillaume Neuttiens, Jonas Sauer
We develop a general principle for passing from the analysis of partial differential operators on the whole space to boundary value problems on the half-space. The reduction separa…
Nilpotent orbits of classical Lie algebras stable under negation
Guillaume Neuttiens, Jérémie Pierard de Maujouy
Gibbs states are probability distributions defined on Hamiltonian G-manifolds that are naturally parametrized by elements of the Lie algebra g. In this paper, we focus on a specifi…
The Time-Periodic Cahn-Hilliard-Gurtin System on the Half Space as a Mixed-Order System with General Boundary Conditions
Guillaume Neuttiens, Jonas Sauer
A well-posedness and maximal regularity result for the time-periodic Cahn-Hilliard-Gurtin system in the half space is proved. For this purpose, we introduce a novel class of comple…
Universal conductance fluctuations and low temperature 1/f noise in mesoscopic AuFe spin glasses
G. Neuttiens, C. Strunk, C. Van Haesendonck +1
We report on intrinsic time-dependent conductance fluctuations observed in mesoscopic AuFe spin glass wires. These dynamical fluctuations have a 1/f-like spectrum and appear below…
