Confined kinetics and heterogeneous diffusion driven by fractional Gaussian noise: A path integral approach

David Santiago Quevedo, Felipe Segundo Abril-Bermudez, Cristiane Morais Smith · 2026

Many complex systems are described by Langevin-type equations in which the noise exhibits long-range correlations and couples to the system in a state-dependent, multiplicative manner, leading to hete…

Local topological markers for Chern insulators in ribbon geometry

Maks Repse, Tomaz Rejec, Jernej Mravlje · 2026

Local topological markers are used to characterize Chern insulators in the presence of spatial inhomogeneities, such as boundaries and disorder. In this paper, we study the local Chern marker in syste…
