Representation of Archimedean Networks and Inclusion: Computational Applications to Percolation and Network Transitions
We present an alternative geometric representation for the eleven Archimedean lattices, in which each site and bond is uniquely labeled by an ordered pair of integers and characterized via a modular function. This structured labeling enables efficient and systematic implementation of computational models on these lattices, without relying on ad hoc indexing, and provides a versatile framework for future studies on regular tilings. As an application, we obtain, for each Archimedean lattice, th…

Descriptor and Graph-based Molecular Representations in Prediction of Copolymer Properties Using Machine Learning
Copolymers are highly versatile materials with a vast range of possible chemical compositions. By using computational methods for property prediction, the design of copolymers can be accelerated, allowing for the prioritization of candidates with favorable properties. In this study, we utilized two distinct representations of molecular ensembles to predict the seven different physical polymer properties copolymers using machine learning: we used a random forest (RF) model to predict polymer pro…

HIF: The hypergraph interchange format for higher-order networks
Many empirical systems contain complex interactions of arbitrary size, representing, for example, chemical reactions, social groups, co-authorship relationships, and ecological dependencies. These interactions are known as higher-order interactions and the collection of these interactions comprise a higher-order network, or hypergraph. Hypergraphs have established themselves as a popular and versatile mathematical representation of such systems and a number of software packages written in vario…

Electron-phonon-dominated charge-density-wave fluctuations in TiSe$_2$ accessed by ultrafast nonequilibrium dynamics
1T-TiSe$_2$ exhibits a charge-density-wave (CDW) transition below 200 K, which is believed to be driven by a hybrid exciton-phonon mechanism, making it a versatile platform for investigating the interplay between electronic and lattice degrees of freedom. Although the corresponding band structure modifications below the CDW transition temperature are well established, only a few reports discuss the occurrence of the CDW fluctuating phase and its spectral features well above the transition tempe…

Correlated interlayer quantum Hall state in alternating twisted trilayer graphene
Trilayer graphene allows systematic control of its electronic structure through stacking sequence and twist geometry, providing a versatile platform for correlated states. Here we report magnetotransport in alternating twisted trilayer graphene with a twist angle of about 5$^{\circ}$. The data reveal an electron-hole asymmetry that can be captured by introducing layer-dependent potential shifts. At charge neutrality ($ν_{\mathrm{tot}}=0$), three low-resistance states appear, which Hartree-Fock…

Global Synchronization in Matrix-Weighted Networks
Synchronization phenomena in complex systems are fundamental to understanding collective behavior across disciplines. While classical approaches model such systems by using scalar-weighted networks and simple diffusive couplings, many real-world interactions are inherently multidimensional and transformative. To address this limitation, Matrix-Weighted Networks (MWNs) have been introduced as a versatile framework where edges are associated with matrix weights that encode both interaction streng…

Implementation of the magnetic force theorem for large-scale calculations of magnon bands: application to yttrium iron garnet
We present an efficient implementation of the magnetic force theorem which allows for direct evaluation of exchange parameters in q-space. The exchange parameters are calculated directly from Bloch states and the implementation does not rely on any mapping onto localized orbitals. This renders the approach well suited for high-throughput computations, where the construction of a localized basis set (for example Wannier functions) often is impractical. We demonstrate the versatility of the metho…
