Graph Coloring with Physics-Inspired Graph Neural Networks [PDF]

open access: yesPhysical Review Research, 2022
We show how graph neural networks can be used to solve the canonical graph coloring problem. We frame graph coloring as a multi-class node classification problem and utilize an unsupervised training strategy based on the statistical physics Potts model ...

An electrostatics method for converting a time-series into a weighted complex network

open access: yesScientific Reports, 2021
This paper proposes a new method for converting a time-series into a weighted graph (complex network), which builds on electrostatics in physics. The proposed method conceptualizes a time-series as a series of stationary, electrically charged particles ...

Machine-Learning-Based Compact Modeling for Sub-3-nm-Node Emerging Transistors

open access: yesElectronics, 2022
In this paper, we present an artificial neural network (ANN)-based compact model to evaluate the characteristics of a nanosheet field-effect transistor (NSFET), which has been highlighted as a next-generation nano-device.

Neural-prior stochastic block model

open access: yesMachine Learning: Science and Technology, 2023
The stochastic block model (SBM) is widely studied as a benchmark for graph clustering aka community detection. In practice, graph data often come with node attributes that bear additional information about the communities.

Benchmarks for physics-informed data-driven hyperelasticity [PDF]

open access: yesarXiv.org, 2023
Data-driven methods have changed the way we understand and model materials. However, while providing unmatched flexibility, these methods have limitations such as reduced capacity to extrapolate, overfitting, and violation of physics constraints.

Chemical pressure induced substantial negative exchange bias on zero field cooled nanocrystalline LaFeO3

open access: yesMaterials Research Express, 2020
We report a distinctly different zero feld cooled negative exchange bias(EB) effect in Ni doped LaFeO _3 nanoparticle where the EB field is both temperature and concentration dependent.

Coherent backscattering in the topological Hall effect

open access: yesMaterials for Quantum Technology, 2023
The mutual interplay between electron transport and magnetism has attracted considerable attention in recent years, primarily motivated by strategies to manipulate magnetic degrees of freedom electrically, such as spin–orbit torques and domain wall ...
