Neural Network Solves Quantum Few-Body Systems
Paolo Recchia submitted an arXiv preprint on Mar 13, 2026 presenting a neural-network framework to solve quantum few-body systems, including identical and nonidentical particles. The model combines adaptive step sizes with Metropolis-Adjusted Langevin Algorithm sampling and GPU acceleration to approximate ground-state wavefunctions, handling harmonic confinement, Gaussian two-body interactions, and three-body forces while outperforming prior ML methods on ten-particle benchmarks. This approach scales favorably, reduces hyperparameter sensitivity, and captures spatial correlations.
Key Points
- 1Demonstrates neural-network framework approximating ground-state wavefunctions for diverse few-body quantum systems, including ten-particle cases.
- 2Achieves lower relative energy errors than prior machine-learning methods while modeling three-body forces and mixed particle masses.
- 3Enables GPU-accelerated, scalable simulations with stable convergence, reducing hyperparameter sensitivity for practical few-body modeling.
Scoring Rationale
Strong methodological advance with lower errors and demonstrable scalability, limited by a single-source arXiv preprint without peer-reviewed validation.
