PARSEC.py: A Python‐Based Real‐Space Kohn–Sham Density Functional Theory Code Accelerated by Machine Learned Charge Density

Journal of Computational Chemistry, Volume 47, Issue 23, September 5, 2026.
PARSEC.py is a Python‐based real‐space Kohn–Sham DFT framework that leverages the Python scientific ecosystem for transparent, modular integration of machine‐learned densities and GPU acceleration. This unified design enables more efficient and scalable first‐principles simulations of large chemical and materials systems. ABSTRACT PARSEC.py is a Python‐

Explicit simplicial discretization of distributed-parameter port-Hamiltonian systems [PDF]

, 2014
Simplicial Dirac structures as finite analogues of the canonical Stokes–Dirac structure, capturing the topological laws of the system, are defined on simplicial manifolds in terms of primal and dual cochains related by the coboundary operators.

Linear Boundary Port Hamiltonian Systems defined on Lagrangian submanifolds [PDF]

, 2020
Recently Port Hamiltonian systems have been extended to encompass an implicit definition of the energy function of the system, by defining it in terms of a Lagrangian submanifold.

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

Advanced Electronic Materials, Volume 12, Issue 18, 21 September 2026.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Scattering for infinite dimensional port Hamiltonian systems [PDF]

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2004
In this paper, an introduction to scattering for infinite dimensional systems within the framework of port Hamiltonian system is presented. The classical results on wave propagation can be extended to generic power propagation phenomena, for example to fluid dynamics or flexible structures.

Passivity Enforcement via Perturbation of Hamiltonian Matrices [PDF]

, 2004
This paper presents a new technique for the passivity enforcement of linear time-invariant multiport systems in statespace form. This technique is based on a study of the spectral properties of related Hamiltonian matrices.

Coupled Dynamics Between Networks and Fields in Physical Space: A Theoretical Perspective

Annalen der Physik, Volume 538, Issue 9, September 2026.
Networks embedded in physical space often communicate through dynamical fields that both mediate and respond to collective behavior. A unified theoretical perspective is presented for these network‐field systems, linking established mathematical frameworks and revealing how feedback between discrete interactions and continuous spatial processes can ...

Conservation laws and open systems on higher-dimensional networks [PDF]

, 2008
We discuss a framework for defining physical open systems on higher-dimensional complexes. We start with the formalization of the dynamics of open electrical circuits and the Kirchhoff behavior of the underlying open graph or 1-complex.

High‐Performance Sustainable Elastomers: New Insights Into Rubber‐Filler and Filler–Filler Interactions for Carbon Black‐Filled Natural Rubber After Recycling by Devulcanization and Revulcanization

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
Recycling rubber has often led to poor mechanical performance. Here we achieved excellent tensile strength and elongation to failure at 50 phr recyclate loading. Mechanical devulcanization led to key differences in filler interaction between virgin and recycled rubbers that were otherwise equivalent in terms of network structure and crosslink density ...
