Stochastic Hamiltonians for correlated electron models

, 2019
Microscopically conserving reduced models of many-body systems have a long, highly successful history. Established theories of this type are the random-phase approximation for Coulomb fluids and the particle-particle ladder model for nuclear matter ...

ClusterNet: Classifying Single‐Molecule Localization Microscopy Datasets with Graph‐Based Deep Learning of Supracluster Structure

Small Science, Volume 5, Issue 12, December 2025.
ClusterNet is a graph‐based deep learning pipeline for classifying single‐molecule localization microscopy (SMLM) data. It acts directly on point‐cloud localization data from a field of view of any size, using features of individual clusters of localizations together with their spatial arrangement.

Competition between antiferromagnetic and charge density wave fluctuations in the extended Hubbard model

, 2019
By extending our {\it victory} implementation of the parquet approach to include non-local Coulomb interactions, we study the extended Hubbard model on the two-dimensional square lattice with a particular focus on the competition of the non-local charge ...

The impacts of woody encroachment on nature's contributions to people in North America and Africa: A systematic review

People and Nature, Volume 7, Issue 11, Page 2585-2601, November 2025.
Abstract Woody encroachment is affecting nature's contributions to people (NCP) in grassy ecosystems around the world, but these impacts have not yet been well summarised. Moreover, the impacts of encroachment are likely to vary depending on the historical ecosystem dynamics, climatic conditions, encroacher species, and the temporal, spatial, cultural ...

Two-particle renormalizations in many-fermion perturbation theory: Importance of the Ward identity

, 2002
We analyze two-particle renormalizations within many-fermion perturbation expansion. We show that present diagrammatic theories suffer from lack of a direct diagrammatic control over the physical two-particle functions.

One-particle irreducible functional approach - a new route to diagrammatic extensions of DMFT [PDF]

, 2013
We present an approach which is based on the one-particle irreducible (1PI) generating functional formalism and includes electronic correlations on all length-scales beyond the local correlations of dynamical mean field theory (DMFT).

A Performant, Scalable Processing Pipeline for High‐Quality and FAIR Environmental Sensor Data

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract High‐resolution environmental monitoring is necessary to record, understand, and predict biogeochemical and ecological changes particularly in coastal systems but brings significant challenges in processing and making rapidly available the resulting data.

Assessment of road network vulnerability using multilayer perceptron surrogates with automated closure propagation

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 28, Page 5325-5350, 28 November 2025.
Abstract Road networks face increasing disruptions, yet vulnerability assessment methods either oversimplify traffic dynamics or require extensive computational simulations. This research introduces a novel approach integrating traffic simulation, graph theory, and machine learning for efficient and accurate vulnerability assessment.

Evidence for spin-triplet odd-parity superconductivity close to type-II van Hove singularities

, 2015
Searching for unconventional Cooper pairing states has been at the heart of superconductivity research since the discovery of BCS superconductors. In particular, spin-triplet odd-parity pairing states were recently revisited due to the possibility of ...
